Understanding Metal Stamping Spring Washers: Design, Function, and Manufacturing Advantages Spring washers-sometimes called disc springs, Belleville washers, or simply spring lock washers-are essential components in mechanical assemblies that require controlled tension, vibration resistance, or load distribution. While they may appear small and simple compared to the larger parts they support, their performance is often critical to the reliability and safety of the entire system. One of the most efficient and scalable ways to produce spring…

Why an OEM Might Move Their Stamping Dies from One Stamper to Another In the world of precision metal stamping, relationships between OEMs (original equipment manufacturers) and their contract stampers often span years or even decades. Yet despite the long-standing nature of these partnerships, situations arise where an OEM decides to relocate its tooling-sometimes dozens of dies-from one stamper to another. This decision is never taken lightly. It carries implications for production continuity, quality, cost,…

In today’s electronics-driven world, electromagnetic interference (EMI) and radio frequency interference (RFI) are major design concerns across industries-from automotive control modules to medical instruments and telecommunications. Metal enclosures play a critical role in shielding sensitive circuits from unwanted electromagnetic noise. Among the various manufacturing methods available, metal stamping has emerged as one of the most efficient, precise, and scalable processes for producing RFI enclosures. This article explores the stamping process, material selection, design considerations, and…

Copper electrical terminals are fundamental components in electrical and electronic systems, providing the interface between conductors and devices. High-volume production of these terminals requires precision, repeatability, and cost efficiency, all of which are achieved through progressive die stamping. This article details the materials, tooling design, process flow, quality control, and post-processing steps involved in the stamping of copper terminals, with emphasis on the factors that influence electrical and mechanical performance. 1. Introduction Electrical terminals must…

During the stamping process metal is not so much cut as it is broken out.  This means that a clean edge only exists for a portion of that edge; and a rougher broken edge shows for the rest.  With traditional punch presses, a good standard was about 1/3 of the material thickness would be cut sheer and the other 2/3 would be broken. The “sheer” or “land” portion of the cut can be improved upon…

We at Acro were so fortunate to add a new designer to our Famiy this year; who brought a fresh understanding of the latest technology.  We’ve now been able to utilize some of the capabilties build into the specifically for metal stamping plug in for solidwards called Lgogpress that we use.  Most beneficially recently; we’ve been able to utilize the “Die Debugger”; which allows us to virtually run the die in one of our presses. …

“Convert our old, 4-slide tooling into standard vertical punch press tooling and deliver parts to us in just two weeks.” At Acro, we welcome challenges. Solving tough problems is what we do best. We had a buyer approach us as a new customer in dire need of parts to keep their supply chain intact. Their previous metal stamper had unexpectedly closed its doors, creating a production emergency. Even before the purchase order was finalized, we…

At Acro, we have a lot of experience with deep drawing a wide variety of materials; but they are usually annealed or soft temper.   Recently a customer came to us with a challenge to do a 2 steep deep draw out of Half Hard Brass (the temper and Tin Content, make this difficult).  As, a matter of fact, HH Brass is more difficult to draw than annealed stainless steeel. Our stamping specific modeling software calculated…

Stamping to a sharp point presents a unique challenge in our industry. The finer the point, the more quickly tooling wears down-and the higher the risk of issues like part distortion, burr formation, and inconsistent tolerances. At ACRO, we specialize in overcoming exactly these kinds of challenges. Recently, we completed a project involving a series of precision parts that not only had to taper to exceptionally fine points but also required a precise radius profile.…

Do you want to impress a toolmaker from another stamper? Show them a part with a hole so small they can’t see it with their name eye! We recently took on production of a washer so small. it pushed the boundaries of what our tooling can do — and we’re proud to say, challenge accepted and conquered. This washer had an incredibly small inside hole — so small, in fact, that none of the commercially…

Whether it as it was in this case, where the previous stamper had to close their doors, or you are just looking for savings via efficiency; Acro can retrofit your old tools to run in our state of the art servo presses. These series of parts are a perfect fit for Acro, as they encompass both deep drawing and they have tight tolerances. Our In-House toolroom, is able to optimize all kinds of older dies.…
