Plastics Technology México: Tipos de bombas de vacío https://www.pt-mexico.com/rss/zones/tipos-de-bombas-de-vacio Tipos de bombas de vacío Las bombas regenerativas son bombas de transmisión directa cuya velocidad puede ajustarse solamente con una unidad variable de la velocidad del motor. La amplia variación de flujo de aire puede limitarse solamente con un control sofisticado o un limitador mecánico de flujo. Las bombas regenerativas de fase sencilla son las más pequeñas, más silenciosas y menos costosas. También tienen la capacidad de vacío más baja (un máximo de 6-9" Hg dependiendo del diámetro del tubo). Estas bombas son ideales para el transporte de cargas ligeras a través de distancias más cortas en los sistemas con tuberías de hasta 2,5 pulgadas de diámetro. Las bombas regenerativas de fase doble son físicamente similares a bombas regenerativas de fase sencilla. Los modelos equivalentes se una y dos etapas tienen el mismo diámetro de la carcasa, pero las carcasas de las bombas de fase doble tiene el doble de profundidad. También utilizan más caballos de fuerza que las bombas de fase sencilla para crear vacíos mayores, hasta de 12" Hg. Estas bombas son ideales para transportar los materiales en distancias y velocidades moderadas, con tuberías de hasta 2.5" de diámetro. Las bombas regenerativas, por la naturaleza de sus principios de funcionamiento y el motor de accionamiento directo, comienzan a una velocidad considerablemente mayor y experimentan una mayor velocidad a menor vacío, comparadas con otros tipos de bombas, que conducen a ramificaciones y que se discuten más adelante en el artículo.   Las bombas PD son típicamente impulsadas por poleas, por lo que su velocidad y flujo de aire es regulable para entregar la apropiada velocidad de transporte del sistema. Esto es particularmente importante con resinas de difícil de manejo y aire más fino en instalaciones de alta elevación. Las bombas de desplazamiento positivo (PD), consideradas por muchos estándar de la industria, proporcionan la más amplia gama del flujo de aire (por ejemplo, 55 a 470+ cfm) y niveles de vacío de hasta 14" Hg. Estas bombas se instalan a menudo para el transporte de resinas a través de largas distancias en sistemas con tuberías de hasta 4" de diámetro o más. Las bombas PD son más eficientes que las bombas regenerativas a un vacío y flujo de aire comparables. También ofrecen un flujo más consistente cuando el vacío varía a través de las aplicaciones típicas del sistema. Y las correas pueden ser configuradas para trabajar a menor velocidad desde el principio. La mayor desventaja de las bombas PD – hasta ahora – ha sido su nivel de ruido – a veces más de 90 dbA. NOVATEC ofrece bombas PD con niveles de ruido inferior a 80 dbA sin atenuación de sonido adicional, proporcionando una gran mejora para el ambiente de trabajo.     La bombas PD de alta eficiencia también puede configurarse y ajustar su velocidad para manejar materiales difícil de transportar y en instalaciones altas. Bombas PD de alta eficiencia Las bombas de PD de alta eficiencia ofrecen un 20% más de capacidad de vacío que las bombas PD estándar. Un mayor vacío produce mayores velocidades en distancias y transporte más grandes. Estas bombas funcionan con vacíos de hasta 14" Hg (máximo hasta 15" Hg) a través de una construcción robusta, que incluye una alta resistencia, un rotor y un cojinete de rodillos helicoidales de tres lóbulos, con modelos que van desde 7.5 hp a 20 hp. Son más eficientes energéticamente que las bombas regenerativas y más silenciosas que las bombas tradicionales de PD en el mismo nivel de vacío.       Bombas de garra se utilizan más a menudo cuando las distancias de transporte son tan largas que otras bombas no desarrollan suficiente nivel de vacío para transportar la cantidad de resina requerida. Bombas tipo garra La bomba de vacío tipo garra es un diseño único pensado para funcionar a niveles muy altos de vacío. El diseño de la garra comprime el aire mientras está dentro de la carcasa de la bomba, aumentando vacío operativo para el transporte hasta 15" Hg (vacío de alivio Hg 17"). Estas bombas vienen en modelos de 4 hp a 15 hp y también consumen menos energía, ya que requieren casi la mitad de energía que las bombas regenerativas y hasta a un 15% menos que las bombas PD estándar, para un vacío y un de flujo de aire determinados. También son más silenciosas que las bombas PD en rangos de vacío comparables. Las bombas de garra proporcionan velocidades de transporte más altas y una mejor capacidad de eliminar obstrucciones que cualquier otra bomba. Sin embargo, el alto costo relativo de estas bombas (tabla 1) generalmente limita su uso, excepto en condiciones inusuales que no pueden ser realizadas por otras bombas.   jue., 2 may. 2024 00:00:00 -0400 Expo Pack México 2024: sostenibilidad, innovación y networking Expo Pack México, la feria de envases más grande de la región, reúne a más de 700 expositores y ofrece soluciones innovadoras para diversos sectores.

jue., 2 may. 2024 00:30:00 -0400 Freeform: Binder Jetting Does Not Change the Basics of Manufacturing Rather than adapting production methodologies to additive manufacturing, this Pennsylvania contract manufacturer adapts AM to production methodologies. In general, this starts with conversation. Additive manufacturing is a digital manufacturing process, but that does not mean the digital part file is enough of a starting point to begin. Nate Higgins and Chris Aiello believe there ought to be much more: a detailed conversation around the aims for the part and the choices affecting it. That is, what are the important functions of the part, and can any features be adjusted for the sake of greater manufacturing speed or reduced cost? In this respect, they say, additive manufacturing is like manufacturing in general.

The muzzle brake is a former assembly, formerly joined through welding, now manufactured in one piece via binder jetting. This part has been cut in half to reveal the internal geometry. 

In fact, in a whole lot of ways, production AM is like industrial production as we have long understood it, they say. Or it should be. That insight is the principle underlying the manufacturing business these two men founded, and have led for four years. Freeform Technologies, headquartered in St. Mary’s, Pennsylvania, is a contract manufacturer launched to deliver part production via binder jetting, and has since expanded into other metal powder- and sinter-based production processes as well.

Higgins is the president. AM is a disruptor, he says, but it doesn’t disrupt the basics. “Just because we have additive, we shouldn’t be blowing up Kaizen, 5S and Lean Manufacturing,” he says. “The fundamentals are valuable.” What this means for Freeform, in practice, is that instead of adapting production methodology to additive, the company has adapted additive to production methodologies. For example, the binder jetting machines are serviced according to a predictive maintenance schedule the company devised itself, drawing on experience with PM schedules for longer-established equipment types such as molding presses. Also, the company’s very choice of binder jetting machines departs from what some would see as the machine type that would be ideal for production, because the Freeform team has come to a different view as to what type of machine fits the needs and pacing of how industrial production ought to flow.

Freeform's capabilities in St. Mary's include binder jetting, mostly on Desktop Metal Shop machines (seen in the background) and a Tritone MoldJet system delivering an alternate mode of sinter-based metal AM.

Recently, the company’s binder jetting capacity expanded considerably. The founders saw an opportunity to acquire the binder jetting part-making facility formerly run by ExOne (now part of Desktop Metal) and bring their industrial production methodology to this site. Thus, the headquarters site in St. Mary’s, which runs six binder jetting machines plus three metal injection molding (MIM) presses and a MoldJet sinter-based additive system from Tritone Technologies (more on this in a bit), has now been joined by a sister location in Pittsburgh running 16 binder jetting machines.

I went to St. Mary’s to walk through the company’s process and spend time on the production floor with the two cofounders. Freeform is in daily production with AM, now serving about 10 to 12 active customers at any given time that each rely on the company for AM part numbers in quantities of 100 to 1,000 pieces per month. About 50 upcoming part-production opportunities at this scale are also in development. As a result, even though the facility also does MIM for higher-quantity work, the sintering furnaces are typically filled with additive parts.

Walking the floor gave a sense of what this work is like. Compared to most other part-making processes, AM is quieter and lower in labor (save perhaps for depowdering, the one potentially labor-intensive step). Other than these differences, in terms of rhythm and repetition, the feel of production at Freeform is … well, like production.

Here is more on what the company set out to build, and on the system and procedures they have developed so far:

How to Adapt a Part to Binder Jetting

Aiello is the VP of business development. He and Higgins founded the business in 2020. Both came from working in MIM, and both were fascinated by the promise they saw in binder jetting. “No one was taking a traditional approach to this non-traditional process,” he says. The company began with two binder jetting machines: a P1 from Desktop Metal and an Innovent from ExOne. All later machines at St. Mary’s have been Desktop Metal’s “Shop” model.

Among other things, the “traditional approach” he refers to emphasizes interactions with customers. Nearly every prospective part offers opportunities for cost saving, he says, if only the designer and manufacturer can better understand one another’s needs. Conversation aims to get to this understanding.

The Freeform team engages in conversations with customers to understand the part's measure of success. If one of them is part consolidation, as in the case of the muzzle brake, then company president Nate Higgins says, “We can win.”

“Wall thicknesses, radii, chamfers — these are the kinds of things we ask about,” Aiello says. In binder jetting, initially printing any form or feature might be straightforward, but design modifications to any of these features might produce more controlled or consistent outcomes in sintering, which is a vital and generally underappreciated part of the binder jetting process. Similarly, if there are many critical features on the part, how these features interact with one another can be important to understand.

This, too, comes down to sintering. Higgins says, “We often ask: Can you give us a flat surface to sinter on?” If a part can rest on its own surface within the oven, this saves Freeform from creating a tool to support it, and this can deliver cost savings that are considerable.

He continues, “We always want to understand how we will measure success. If the aim is lightweighting, or assembly consolidation, or speed to market, then we can win.”

Binder jetting makes it possible to nest parts to 3D print batches of components at once, but there are limits. Company VP Chris Aiello explains: Because this is production, like parts are all oriented in the same direction. To do otherwise would introduce a variable that might make one production part different from another.

Parts With Fewer Pieces, More Variety

The industries the company now serves include defense, medical and industrial machinery, as well as various narrower markets. For example, one component I saw in production (details are proprietary) relates to a forthcoming new product for the food service industry.

Another sector is firearms. One production part the company runs that was redesigned for additive is a firearm muzzle brake. Formerly the part was an assembly consisting of the muzzle brake geometry plus a tube, cap and nut, all welded together. Binder jetting is not cheaper than any one of these pieces alone. However, binder jetting proved significantly cheaper than the assembly. 3D printing the former assembly as one solid unit saves the customer the cost of sourcing and assembling the components.

This surgical reamer was previously made through stamping. It still could be made that way, except the provider wants to offer many more size varieties. If the reamer proceeds to full production, which Freeform expects, parts will be 3D printed via binder jetting in mixed sizes, according to which sizes are needed. This kind of nimbleness favors AM, and it also speaks to why Freeform has built its AM process around smaller-capacity machines delivering production it can turn more quickly.

In addition to assembly consolidation, part variety is another reason additive wins. An example here is a surgical reamer used to prepare patients for acetabular hip implants. The reamer is traditionally made through stamping, in just a few different sizes for the tool, but the OEM wants to offer reamer size options in every 1-mm increment of diameter to better tailor the tool to each patient. That many reamer sizes would mean too many stamping dies to be economical, so binder jetting is the cost-effective choice. The tool has not yet entered production, but when it does, the goal is to produce 10,000 per year. The catch is this: Reamers will be made essentially on demand, so any build might contain any mix of different reamer sizes. This kind of variable production batching argues for additive, because a stamping process would have to run many identical pieces before changing the die.

Freeform says the desire to offer this kind of production nimbleness was one of the factors that informed its choice of binder jetting platform.

Sintering furnaces do not run every day. Capacity is larger than a day's additive production, large enough sometimes to run a month's quantity of multiple AM jobs at once.

Return on Turns: The Case for Smaller AM Build Volume

The St. Mary’s facility relies largely on the Desktop Metal “Shop” system, running five of these machines and dedicating different machines to different metals. The maker of this machine model introduced it with the idea that it might be a natural metal 3D printing option for CNC machine shops. Freeform’s leaders see it as something different: their preferred platform for additive production. While other binder jetting machines offer larger chambers able to produce more parts in a single build, Freeform sees the limited build size of its machines (the Shop system is available in sizes up to 16 liter, but Freeform does not use the largest model) as an advantage instead of an impediment.

“Eight- to 10-liter build size is the sweet spot for our work,” Higgins says. “For us, bigger build volume does not yield more return. More turns are what yield us more return.”

On the Shop machines, he says, one build — including 3D printing, curing, depowdering and sintering — can be turned in five days. A bigger build envelope would allow more pieces to be 3D printed in one batch. However, turn time would then be longer, and the chance to be responsive for make-to-order opportunities like the hip reamer would be compromised.

Plus, for jobs that call for a larger number of pieces in one run, the company has an option. Contrasted with MIM providers that have expanded into binder jetting as an extension of their capabilities, Freeform presents the very opposite picture. This additive provider expanded into MIM.

MIM, Plus Tritone as “Digital MIM”

Aiello says, “When we got started, we had no interest in providing metal injection molding.” There is a lot of competition, he notes. However, MIM is the right process for certain higher-volume parts. That became apparent almost at once, when one of the company’s very first successes with production binder jetting scaled in exponential steps. The first order for the part was five pieces, then after a design change came an order for 50, then after another design change was an order for 500 more. The product proved successful, so that the customer’s need soon rose to 50,000 per month — far too much for Freeform’s AM capacity to keep up with. The team knew someone would make the parts through MIM. Aiello says, “We have the furnaces and the sintering expertise,” and he notes that the company’s additive production jobs often specify MIM material standards, so this is the realm in which they were already working. “So we said OK to MIM,” he says. Today, there are six recurring MIM customers, enough to support three presses.

Higgins notes the value of the Tritone MoldJet system is in depowdering, sometimes a weakness of binder jetting. MoldJet 3D prints a mold for the powder metal as part of the process. The capability is relatively new for Freeform, but the company has already discovered some additive parts it can only produce on this machine because of the way part geometry inhibits powder removal.

Another important capability expansion has involved a process different from MIM, albeit not entirely: the “MoldJet” process from Tritone. Freeform has a Tritone machine in St. Mary’s running alongside its binder jetting systems. The process is, in a sense, “digital MIM,” says Higgins, because the multi-station carousel machine works by 3D printing a mold (in wax) into which it applies a blend of powder metal and binder during the same cycle. Each layer of wax plus binder plus metal is hardened as part of the sequence, with the complete wax mold later removed prior to sintering the part it helped to produce. Like MIM, this alternate method of sinter-based AM offers freedom from depowdering, an often-problematic step in binder jetting.

The capability is new for Freeform, but even so, Higgins says the company has already seen “two, maybe three parts that we can only make with the Tritone.” Plus, certain other parts that could be made through binder jetting have proven easier here.

The company runs metal injection molding on three lines. The company did not originally expect to offer MIM, but it proved valuable for supporting some customers scaling to higher volumes. (Unrelated: Freeform's neighbor in its facility is a maker of beer cans. That other company's inventory is visible here.)

In the past, Higgins says, “There were people we were saying no to because we could not see a way to depowder their geometry.” Here as well, conversation with prospects is valuable for identifying the best wins for additive — and having this additional AM capability allows conversations to arrive at yes more often.

More Years Than Weeks: The Ryerson Investment

The very biggest capability expansion came with the purchase of the ExOne part production facility. This also is still new. Higgins and Aiello are mindful of wanting to proceed slowly with integration, to more fully preserve and leverage the possibilities of this site, including the expertise here. The facility offers not just more binder jetting, but also knowledge base — related to multimaterial infiltrated binder jet parts, for example — that represents meaningful new offerings for the company. Yet over time, the two sites will come to operate more and more like one another, as they both are organized around the same fundamental philosophy of production. Freeform hopes the investment in more capacity will bring them more opportunities for conversation with customers that lead to production work.

The assurance of stability is one more foundational element of success in manufacturing that figures in here, the company leaders say — albeit not one that is as quantifiable in its impact as, say, Lean or Kaizen. But stability is a value Freeform has wanted to convey nonetheless. The acquisition and integration of the ExOne site helps with this, but the purchase was possible in part because of an investor that also responded to, and is now helping to reinforce, that stability. In 2022, metal distributor and processor Ryerson became an investor in Freeform. At the time of this investment, Aiello notes, the larger company had more years in business that Freeform had weeks. Ryerson, with about 100 locations and about 4,000 employees, was founded in 1842.

“They understood that we are not trying to flip this company in five years,” Aiello says. The investment brings capital and guidance, and helps convey the same point about long-term ownership to potential production customers. Thus, Freeform’s reward for looking and operating more like an industrial enterprise, and less like a technology startup, has been to win the validation and support of a larger and older industrial enterprise.

Higgins says, “During their first visit, they took a look around and said, ‘At least you guys don’t have a ping pong table.’”

jue., 2 may. 2024 00:00:00 -0400 Heule Spot Facing, Counterboring Tool Provides Flexible Machining The Solo L tooling system for spot facing and counterboring is well suited for a wide range machining applications.
SOLO L tooling for spot facing and counterboring
Source: Heule Precision Tools

Heule Precision Tools introduces Solo L tooling for spot facing and counterboring projects over 25 mm. Front and back counterbores up to 1.95-times bore diameter can be produced in bores ranging from 25.0 - 45.0 mm in diameter.

Solo L features a simple, reliable design which functions without an anti-rotation device, change in spindle rotation, coolant pressure or contact mechanism. This sealed system prevents coolant contamination, and the pin-driven cutting blade, which moves in and out radially, prevents chips from jamming the system. Solo L is designed to be customizable, with the tool’s blade housing, blade control and blades individually designed to meet specific project requirements. This specialized system cuts interruptions and difficult materials like nickel, titanium and other exotic alloys, making it well suited for a wide range of CNC, transfer, multi-spindle and conventional machining applications.

The Solo L uses two centrifugal weights installed in a sealed tool head. With an activation speed rate of 1,600 rpm or higher, the weights start moving outwards and turn the gearwheel, which drives the blade out by rotating the blade control. When the spindle is stopped and then actuated to cutting speeds, a pullback spring pushes the centrifugal weights back to the center and the blade extends to the cutting diameter. Maximum machining speed is 900 rpm.

In addition to the L model, three other Solo models are available, each is capable of counterboring two times the bore diameter minus 1 mm. Possible applications up to 40 mm through hole depending on the counterbore to bore ration and parameters. In most cases through-coolant is optional, with a 280-psi maximum.

Smart Control For Industry 4.0

Ewikon is also highlighting its previously introduced Smart Control product. The product is a measurement solution that integrates data from the hot runner system into networked injection molding production. By monitoring temperatures and residence times, and calculating shear rates at various positions, Smart Control provides data transparency that enables process optimization and quality management. The product also provides assistance with troubleshooting and can identify the need for maintenance tasks. All data can be exported via WLAN or ethernet.

Liquid Silicone Rubber

In addition to hot runner injection molding of thermoplastics, Ewikon also offers solutions for LSR. The company’s Coolshot product is a cold runner system featuring electric drive valve gate technology. According to Ewikon, the motors enable high precision valve pin positioning in steps of 0.01 mm, to fine-tune cavity filling.

jue., 2 may. 2024 00:00:00 -0400 NPE2024 and the Economy: What PLASTICS' Pineda Has to Say PLASTICS Chief Economist Perc Pineda shares his thoughts on the economic conditions that will shape the industry as we head into NPE2024.
Perc Pineda, the Plastics Industry Association's chief economist.

Perc Pineda, the Plastics Industry Association's chief economist.

The plastics economy retracted last year amid an economic turndown. What’s in store for this year, when NPE2024 takes place?

Plastics Technology’s Editorial Director Jim Callari asked Perc Pineda, the Plastics Industry Association’s chief economist, to polish his crystal ball and provide some insights.  

Q: How would you characterize 2023 for the plastics industry, and what are your expectations for the U.S. economy as we roll toward NPE2024?

Perc Pineda: Assessing the plastics industry landscape in 2023 reveals a year marked with nuanced shifts across various sectors. From the fluctuations in production levels and shipments to the intricate interplay between labor constraints and export dynamics, the plastics industry encountered challenges and opportunities. Notably, the year witnessed divergent trajectories. While certain segments, such as plastics material pricing and resin manufacturing, grappled with equilibrium adjustments, others, like the mold for plastics trade, mirrored global economic oscillations. For an industry that thrives on innovation, the forthcoming NPE, the largest gathering in the Western Hemisphere for the plastics industry, offers an avenue for post-COVID-19 in-person reconnection of the industry’s supply chain. And the net benefit of which should be positive.

Q: What about the global economy?

A: In early fall 2023, there was a consensus anticipating moderate global economic growth in 2024. At the annual meeting of the International Monetary Fund (IMF) held in Morocco in October 2023, where I was in attendance, the IMF projected a 2.9% growth rate for the year. The expectation was that advanced economies would experience a growth of 1.4%, while emerging and developing economies were forecasted to grow by 4.0%, maintaining the same rate as in 2023. The divergence among regions in this outlook implies potential variations in the performance of the plastic industries across countries.

For the U.S., the primary focus will be on three key countries: Mexico, Canada and China, as they represent the top three largest export markets for the U.S. plastics industry. The current outlook suggests growth rates of 2.1%, 1.6% and 4.2% for Mexico, Canada and China, respectively, in the current year.

However, this optimistic scenario is contingent on the global economy avoiding significant negative shocks, such as an escalation of ongoing geopolitical challenges that could disrupt the supply chain. In the absence of such disruptions, it is plausible that global trade in plastics could once again surpass the World Trade Organization's (WTO) forecast for merchandise trade volume, which currently stands at a projected growth rate of 3.3%. Monitoring potential risks and uncertainties in the geopolitical landscape will be crucial in assessing the resilience of the plastics industry in the face of evolving global economic conditions.

Q: Is the industry still impacted by supply chain issues?

A: The challenges within the supply chain landscape today have shifted from being directly attributed to the COVID-19 pandemic to encompassing broader structural issues within the economy. These challenges are notably linked to demographic shifts, a lower participation rate and a shortage of skilled workers. In November of the preceding year, the capacity utilization in plastics and rubber products manufacturing stood at 76.6%, marking a decline from the 80.4% reported a year earlier. This decrease can be attributed, in part, to a reduced workforce in plastics and rubber manufacturing, despite the unemployment rate in this sector remaining significantly lower than the overall civilian unemployment rate in the broader economy.

It is noteworthy that these supply chain issues are no longer as acute as they were two years ago. The current scenario, while still influenced by economic dynamics, is less directly impacted by the immediate challenges posed by the COVID-19 pandemic. The supply chain disruptions are now more entrenched in the structural aspects of the economy. However, it is important to acknowledge that the stability of the supply chain remains contingent on avoiding significant negative shocks to the global economy, particularly any escalation of ongoing geopolitical challenges that could potentially disrupt the supply chain. As of now, barring such unforeseen disruptions, the pressing nature of supply chain issues has diminished compared to the challenges faced two years ago.

It is noteworthy that these supply chain issues are no longer as acute as they were two years ago.

Q: Are you optimistic about the manufacturing economy in the U.S. in particular? Have you seen much evidence of reshoring?

A: Reshoring is inherently a medium- to long-term initiative, making it challenging to quantify in the short term. However, this does not mean it’s not happening. There’s data on reshoring and foreign direct investment (FDI) manufacturing job announcements. Despite efforts such as acquiring existing manufacturing facilities or transitioning to domestic suppliers, the pace of reshoring appears to be less conspicuous than policymakers might prefer.

Several factors contribute to the relocation of manufacturing to other countries, including labor supply and cost, energy and transportation costs, and the ease of doing business. An assessment of how the U.S. compares to other nations in these three aspects is essential to understanding the outlook for U.S. manufacturing. There’s also the attractiveness for foreign companies to manufacture in the U.S., considering we are the largest market in the world for manufactured goods.

Presently, the U.S. remains optimistic and any potential pullback in manufacturing activity in 2024 is anticipated to be less pronounced than what was observed in 2023. This optimism is grounded in the evaluation of factors influencing manufacturing dynamics and their alignment with the broader economic landscape.

Q: Processors spend most of their time at their plants making sure product is made on time at high quality. But when they are forecasting their business, can you provide some guidance on the indicators they should be tracking?

A: Those in the plastics industry generally comprehend that the sector is mature, and its expansion closely mirrors the overall economic growth, typically gauged by the increase in Gross Domestic Product (GDP). The monthly counterpart to GDP is the Industrial Production Index, serving as an economic indicator. However, it is crucial to note that both GDP and the Industrial Production Index are lagging indicators, reflecting changes after shifts in the macroeconomy have occurred.

Effective business forecasting necessitates the consideration of a blend of lagging, leading and coincident indicators to obtain a comprehensive understanding of economic trends. Building permits and housing starts, for instance, are a good leading indicator suggesting future construction and housing demand. It’s worth noting that business forecasts tend to be specific— sales forecast, expense forecast, new product launch forecast, for instance— have different dimensions. Within the realm of business forecasting, there’s no one size fits all, and forecast models need tweaking over time.

Effective business forecasting necessitates the consideration of a blend of lagging, leading and coincident indicators to obtain a comprehensive understanding of economic trends.

When it comes to thread rolling, having the right tools can significantly streamline the process, ensuring accuracy and minimizing downtime.

Unlike subtractive processes, thread rolling does not remove material but instead moves and molds ductile metals quickly and precisely into the thread form using a cold-forming process. Thread rolling is completed using a thread rolling attachment on a multi-spindle, Swiss-type or CNC lathe. During the process, the tooth form of the thread rolls protrudes into the outside diameter of a cylindrical blank workpiece to reform the surface. The extreme pressure from the thread rolls causes the blank material to flow outward into the cavity between the thread rolls. This produces thread geometry that mirrors that of the rolls.

CJWinter, a provider of thread rolling solutions, simplifies complex calculations for engineers and manufacturers with an array of thread rolling calculators. These calculators, which are available on the company’s website, are designed to optimize thread rolling operations. Here are four:

Pitch and Blank Diameter Calculator. Determining the pitch and blank diameter is crucial for achieving precise thread dimensions. By selecting the thread size and desired pitch, CJWinter’s Pitch and Blank Diameter Calculator instantly generates the required blank diameter, along with the minimum and maximum pitch diameter values. This saves users valuable time and ensures accuracy in setup specifications, enabling smoother attachment installation and operation.

This calculator indicates whether the material is suitable for thread rolling.

Material Thread Rollability Calculator. Choosing the right material for thread rolling can be challenging. The company’s Material Thread Rollability Calculator simplifies this decision-making process by evaluating material properties such as elongation, tensile strength and hardness. With a simple input of these parameters, the calculator indicates whether the material is suitable for thread rolling. The color-coded results provide a quick visual assessment, enabling manufacturers to make informed material selections for optimal thread rolling performance.

By providing load values at different rolling pressures, manufacturers can adjust parameters accordingly to achieve desired thread characteristics.

Thread Load Calculator. Understanding the load requirements for thread rolling is essential to preventing equipment damage and ensuring consistent thread quality. CJWinter’s Thread Load Calculator facilitates this by calculating the approximate load required based on material, blank diameter, thread length and the company’s attachment specifications. By providing load values at different rolling pressures, manufacturers can adjust parameters accordingly to achieve desired thread characteristics. The calculator’s interface and visual indicators are designed to simplify the process and enhance user experience.

This calculator considers factors such as thread per inch (TPI), material hardness and number of starts.

Penetration Rate CalculatorAchieving the right penetration rate is vital for thread forming and knurling operations. The company’s Penetration Rate Calculator streamlines this calculation by considering factors such as thread per inch (TPI), material hardness and number of starts. By inputting these parameters, the calculator computes recommended part revolutions and corresponding compensator revolutions, optimizing production efficiency while maintaining quality standards. This tool enables manufacturers to fine-tune their processes for optimal performance and productivity.

By providing accurate calculations and intuitive interfaces, these calculators simplify complex tasks, reduce errors and enhance overall efficiency. As CJWinter continues to expand its knowledge database, users can expect ongoing advancements and improvements with the manufacturing processes.
