Die Science: Understanding and calculating draw reductions
- By Art Hedrick
- Sep 1, 2017
- Article
Splitting, wrinkling, and surface defects are common problems in drawing, a process in which metal flows into a die cavity. Often these problems result from incorrect performance of the draw reduction process. A draw reduction is a multistep process in which the surface area of the original blank...

Die Science: Successful extruding techniques
- By Art Hedrick
- Sep 1, 2017
- Article
Attempting to produce an extrusion or flanged hole often can be a frustrating process. You must constantly battle geometric features such as roundness, flange height, and diameter. In fact, preventing the flange from tearing is one of the most common problems associated with extruding. Numerous...

R&D Update: Sheet hydroforming (part II)
- Sep 1, 2017
- Article
Sheet hydroforming (SHF) can be conducted using a punch and a pressure pot (SHF-P) or female die (SHF-D) with a pressure medium such as water or oil. In either case, process parameters, specifically the blank holder force and the pressure medium, simnifically influence part quality in the forming...

R&D Update: Analyzing springback in double-curved autobody panels
- Aug 31, 2017
- Article
Springback is the elastic recovery of nonunifomrly distributed stresses in a deformed part after the forming load is removed. Predicting springback and modifying the tool geometry accordingly are essential for stamping precessions parts and controlling tolerances. The magnitude of springback is...

Die Science: Preventive die maintenance procedures
- By Art Hedrick
- Aug 31, 2017
- Article
Die maintenance. Die repair. What’s the difference? If you find your daily activities include task such as fixing broken pads, welding a damaged die section after a dowel falls out of the upper half, digging two parts out of a draw die, or replacing pilots that have pierce holes in a progressive...

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...

Custom stampings produced from customer CAD drawings
- Aug 29, 2017
- Product Release
Lee Spring works from customer CAD drawings to develop short-run and prototype stampings and assemblies through a complete process validation procedure including first articles and production part approval processes. Typical products include latches, retainers, bridging parts, special conductors,...

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...
