STAMPING Journal

STAMPING Journal is the only industrial publication dedicated solely to serving the needs of the metal stamping market. In 1987 the American Metal Stamping Association broadened its horizons and renamed itself and its publication, known then as Metal Stamping.

Die Science: What really makes a press shop work?

February 24, 2017 | By Art Hedrick

As stampers, we often believe that purchasing new machines and investing in new technology are key to remaining competitive in the global market. Although keeping up with the latest equipment and techniques is very important, it’s not the only answer for having a successful stamping company....

Die Science: Opportunity knocks

February 24, 2017 | By Art Hedrick

When you think of the tool and die industry, you often think first of tool- and diemakers—people grinding die sections, reading engineered drawings, assembling dies, and trying out tooling. Although tool- and diemakers are critical to the diemaking process, many jobs are equally important to the...

Die Science: The influence of product design

February 24, 2017 | By Art Hedrick

I find it somewhat disheartening how often product designers fail to see the downstream effect of the decisions they make regarding the design of a stamped product. Poor tolerencing and part feature decisions cost the stampers and die builders any profit they may have realized. While I don’t want...

Die Science: Die costing and estimating

February 24, 2017 | By Art Hedrick

One of the common complaints I hear from stampers is that tooling cost estimates differ significantly when they are requesting quotes. One would think that if every shop were quoting to the same die design standards, the tooling cost would be similar from each shop quoting, but that’s not the...

Safe-to-sewer solutions simplify disposal

February 23, 2017 | By Kate Bachman

he type of cleaning solutions and lubricants a stamping manufacturer uses during and after forming determines whether it must dispose of them as hazardous waste, which requires transporting them to an off-site haz waste facility or simply discharge them to on-site sewering systems. Here is what to look for in ecofriendly metalworking fluids.

Auto stamper gets two coil feed lines for the size of one

February 23, 2017 | By Kate Bachman

The Adient Co., automotive seating, stamping, and assembly plant in Athens, TN was struggling with material damage and accuracy feeding thin material handling on its current compact feed system. It resolved the problems by installing two compact Dallas LoopSelect SpaceSaver™ dual loop/feed systems that allow it to run very thin materials in the front loop, and then switch to a back loop for thick materials.

Advancements in furnace design improve hot stamping

February 16, 2017 | By Borek Dvorak, Jad Tawk

New roller furnaces for hot stamping have been designed using finite element method (FEM) analysis for numerical simulations of heating processes and heating power distribution. The advanced designs focus on optimal heating, modern roller drives, a new approach to the furnace’s input and output without movable parts, and other items with respect to the optimal technological and technical aspects to enhance the ability to perform nonuniform (Taylor) tempering and hardening.

Die Science: What makes a topnotch metal stamping plant?

January 11, 2017 | By Art Hedrick

Some stamping plants and die-building facilities are far more productive and efficient than others. Each shop typically has its own niche, as well as its own strengths and weaknesses. So what are the key decisions managers make that result in a successful stamping or die-building shop? Staffing...

Ask the Expert: How do we fix our slug pulling problem?

January 11, 2017 | By Thomas Vacca

Q: We are developing what we thought would be a fairly straightforward stamping. We are blanking a rectangular shape, 2.15 by 2.35 inches and 0.004 in. thick, from 301 stainless steel. A simple, single punch blanks the part through the die chase in one shot. But as we brought up the stamping speed...

Auto Suppliers Partnership for the Environment builds strong companies 5 ways

December 15, 2016

Considering the competitive state of the automotive industry, any kind of best practices sharing and collaboration among automotive OEMs would seem counter-intuitive. Yet, on the important topic of the environment, major automakers and top suppliers have been doing just that since they formed the...

R&D Update: Predicting springback when bending AHSS and aluminum alloys, Part 1

December 5, 2016 | By Aanandita Katre, Ali Fallahiarezoodar, Taylan Altan, Ph.D.

Editor’s Note: Part II of this article, which will appear in the January/February 2017 issue, will discuss the results and case studies of the newly introduced inverse analysis method for improving springback prediction. In the automotive industry, the use of advanced high-strength steels (AHSS)...

Die Science: Estimating die cost

December 2, 2016 | By Art Hedrick

Before receiving a contract to design and build a die, the building shop must quote a price to the customer. Because every die usually is a one-of-a-kind tool, the process of quoting tooling cost is not always easy. The person estimating this cost must have a good understanding of sheet metal...
