Die Science: Solving stretch flange problems
- By Art Hedrick
- Aug 30, 2017
- Article
One of the most valuable tools that I have used when processing or troubleshooting stamped parts, especially parts with difficult geometries or features such as long stretch flanges, is called a rubber skin. It is a simple rubber model of a part, constructed using readily available products and...

Die Science: Understanding, designing, and fitting draw pads (Part II)
- By Art Hedrick
- Aug 30, 2017
- Article
Draw Pad Shape Depending on the part shape, draw pads can be different shapes, sizes, and thickness. Parts with a great deal of contoured shape and curvature often use a pad that is curved with respect to the part shape; square or rectangular parts with flat bottoms usually use a flat pad (see...

Die Science: Carrier design for progressive dies, Part II
- By Art Hedrick
- Aug 29, 2017
- Article
One of the common problems associated with progressive dies is the inability to feed smoothy. Carrier strips often are too weak to support the weight of the strip, and this lack of strength is compounded when the strip begins to be fed through the die. Obviously, if the strip cannot be fed...

Die Science: Busting Myths (Part I)
- By Art Hedrick
- Aug 28, 2017
- Article
I love watching the show “MythBusters” on TV. In this reality show, two crazy guys go out an blow up stuff, burn stuff, and break and crash stuff, all in the interest of providing or disproving a myth. A lot of the information that we learn as toolmakers s passed down to us and, unfortunately,...

Die Science: Controlling metal flow with a blank holder
- By Art Hedrick
- Aug 28, 2017
- Article
The key to any successful metal drawing or stretching operation is the ability to control the metal’s flow. Numerous factors influence how much stretch and flow take place during a metal forming process, including the mechanical properties of the metal being formed, the geometry of the part being...

Die Science: Successful stamping: It's a 'we' thing
- By Art Hedrick
- Aug 25, 2017
- Article
As a consultant and educator, I travel to numerous die shops and stamping plants, and almost all of them have the same basic request: “Can you show these tooling guys how to make the dies run better?” I hear comments like “We sure have a lot of downtime and scrap, not to mention the usual...

Die Science: Circle grid analysis for diemakers
- By Art Hedrick
- Aug 25, 2017
- Article
In visits to numerous stamping and die building facilities, I’ve observed that most have circle grid analysis equipment on hand, usually confined to the metals laboratory. This is especially true for the stampers performing deep drawing or stretching. Circle grid analysis (CGA) has long been...

Die Science: Busting Myths (Part II)
- By Art Hedrick
- Aug 25, 2017
- Article
Myth 4—Tool and Die Designing and Building Are Art Forms When I think of art, I think of someone painting or sculpting a project that is a reflection of some feeling, event, or location. A painter, for instance, most likely is not concerned whether the painting will “work”, as it often is an...
Squaring up your next nonround bending application
- By Steve Parrow
- Aug 24, 2017
- Article
The use of square and rectangular tubing is on the increase. Fabricators who understand the processes, material, and tooling stand the best chance of success in bending these shapes, which are substantially more challenging than like-sized rounds.

Die Science: Listening to your parts
- By Art Hedrick
- Aug 24, 2017
- Article
I recently had the chance to engage in some very interesting conversation with the head of sheet metal formability lab for a very large automotive stamper. During our discussion, we looked at numerous parts and talked about common formability problems such as cracks,necking, wrinkles, loose metal,...

R&D Update: Sheet hydroforming
- Aug 24, 2017
- Article
Sheet hydroforming (SHF) was not considered for automotive manufacturing until recently because of its high cycle time. However, recent advancements in hydraulics, press design, and controls have reduced cycle time considerably, making SHF attractive to automakers. For example, General Motors...
