Recreate Chinese Designed Tooling

October 7, 2026

A customer needed USA made components for Buy American requirements.  After discussing their needs for a small reel to reel terminal made in a 2-Out Progressive die; the best solution wound up being just taking the tooling die design already proved out in China and building an exact duplicate in Milwaukee, WI.

Understanding Tolerances in Metal Stamping

September 21, 2026

What Engineers and Manufacturers Need to Know In metal stamping, precision is often critical to how a component performs in the finished assembly. A stamped metal part may need to fit around another component, maintain a precise electrical connection, accommodate a press-fit bushing, or meet specific dimensional requirements throughout high-volume production. Metal stamping tolerances define how much a finished part is allowed to vary from its specified dimensions while still meeting the requirements of the…

Deep Draw 1mm Wide x 3mm Deep

August 7, 2026

Deep Drawing a Tiny Brass part almost 3 times deeper than it is wide required more than10 Draw Stations.  This was a very challenging part that defied what most of our software told us would be required to produce.  Human trial and error is still required in a lot of instances.  The saying “More Art, Than Science” still applies to metal stamping in a lot of instances

Specifying Metal Inserts For Injection Molding

June 22, 2026

How Plastic and Rubber Injection Molders Should Choose Metal Inserts for Their Parts In plastic and rubber injection molding, the metal insert is often one of the most critical components in the finished assembly. Whether the insert is used for threading, electrical conductivity, structural reinforcement, wear resistance, grounding, or mounting, the wrong insert choice can lead to cracking, pull-out failures, corrosion, dimensional instability, or premature product failure. For OEMs and molders alike, selecting the correct…

How Material Stretches When Deep Drawn

May 14, 2026

Diagram of Material Thinning In Deep Draw   How Material Thins During Deep Drawing: What Engineers Need to Know Deep drawing is one of the most efficient and precise metal forming processes used in modern manufacturing. It allows flat sheet metal to be transformed into cups, cans, housings, shells, and complex cylindrical or rectangular shapes with excellent repeatability. At Acro Metal Stamping, deep drawing is a core capability used to produce tight-tolerance components for demanding…

More Dies Sent To Acro

January 28, 2026

When a Customer Sends “The Rest” of the Dies: What That Really Means   In metal stamping, trust isn’t built with promises. It’s built with parts. Recently, we had a customer send us the last of their remaining dies after we successfully took over production on their initial tool transfer. That moment says more than any sales pitch ever could – and it highlights what really matters when transferring customer-owned tooling. This wasn’t just a…

Pre-Tempered vs. Post-Heat-Treated Metal Stamping

January 20, 2026

Design & Manufacturing Expertise from Acro Metal Stamping Choosing whether to stamp parts from pre-tempered material or to heat treat after stamping is one of the most important decisions in precision metal stamping. The choice affects part performance, tooling cost, dimensional stability, lead time, and long-term quality. At Acro Metal Stamping, we help engineers and purchasing teams make the right decision early-avoiding unnecessary secondary operations, tooling issues, and redesigns. With decades of experience stamping spring…

Specialize In Customer Owed Tooling

January 19, 2026

Acro Metal Stamping: The Ideal Partner for Transferring Your Customer-Owned Tooling In the world of precision metal stamping, tooling ownership and performance are two of the most critical factors that determine production success. For manufacturers who rely on external stampers, the need to transfer dies-whether due to capacity constraints, quality challenges, or a stamper closing their doors-is a reality that demands a reliable partner. That’s exactly where Acro Metal Stamping shines. With over 80 years…

Do I Own My Tool?

December 19, 2025

Tooling Ownership in Metal Stamping: What Customers Should Know-and How We Handle It In metal stamping, tooling is everything. Progressive dies and form tools represent a major investment; and play a critical role in part quality, consistency, and long-term supply stability. Yet one of the most common-and most misunderstood-questions customers have is: “Do we own the tooling?” At Acro Metal Stamping, we believe tooling ownership should never be ambiguous. Clear expectations protect both the customer…

Updated Metal Part Costs Guide

December 11, 2025

Download PDF Below are the primary factors that influence the total cost of a metal component-from concept through production. Understanding these drivers helps identify opportunities for cost reduction without sacrificing performance or reliability. 1  Production Method – Often the Largest Cost Driver Production method is typically dictated by volume, but tolerances, material type, geometry, design complexity, and functional requirements also influence the choice. Approximate order of decreasing cost (highest → lowest): Machining Metal Fabrication (laser,…
