Die Science: The top 5 drawing die violations
- By Art Hedrick
- Oct 6, 2015
- Bending and Forming
- Article
Deep-drawing failures—from splitting to scoring to shock lines—often are a result of common engineering mistakes. These problems can occur whether you are using a single-station drawing die, multiple drawing stations, or drawing reductions. Let’s take a look at the five most common...

Die Science: Drawing and stretching
- By Art Hedrick
- Jul 1, 2015
- Bending and Forming
- Article
When I conduct training seminars on drawing and stretching, I usually bring with me a variety of unusual parts made using those processes. Often, attendees ask how to stretch the metal into a shape such as a deep can or deeply formed part without splitting the metal. I simply answer: “We don’t....

Die Science: Slug pulling—Causes and solutions
- By Art Hedrick
- Jun 11, 2015
- Bending and Forming
- Article
Slug pulling in a stamping die can be costly and frustrating. One pulled slug can cripple production. What Is Slug Pulling? When a pierce punch creates a hole, it also produces scrap, called the slug. When the slug sticks to the face of the punch during withdrawal or comes out of the button...

Die Science: Step-by-step troubleshooting of stamping dies, Part I
- By Art Hedrick
- Mar 6, 2015
- Bending and Forming
- Article
Opinions on how to troubleshoot a stamping operation are not in short supply at any production stamping or die-building shop. I’m not trying to stereotype diemakers, designers, or technicians, but their decisions often are made based on insufficient data. Statistically speaking, if I...

Die Science: Step-by-step troubleshooting of stamping dies, Part II
- By Art Hedrick
- Mar 6, 2015
- Bending and Forming
- Article
In Part I of this article, which appeared in the January/February 2015 issue, I discussed the first two basic steps in troubleshooting: Identify problems with the part and verify the die and press setup parameters. Following are the remaining seven steps in the process. Step 3—Reassess and...

Die Science: Attempting to defy the laws of physics, Part II
- By Art Hedrick
- May 10, 2011
- Bending and Forming
- Article
It is almost unrealistic to expect some stamped part part features, such as hole position and flatness, to remain within a small tolerancing zone.

Die Science: Attempting to defy the laws of physics, Part I
- By Art Hedrick
- Mar 11, 2011
- Bending and Forming
- Article
The forms and positional tolerances called out on product designs often defy the physical abilities of the product's material. Proper product and process design, as well as pressure clamping, can help maintain strict tolerances.

- By Art Hedrick
- Dec 13, 2010
- Bending and Forming
- Article
This article continues the discussion of deep-drawing and stretching variables begun in Part I by describing friction, thermal expansion, metal topography, and forming speeds and how they affect metal forming operations.

Deep-drawing and stretching variables – Part I
- By Art Hedrick
- Oct 21, 2010
- Bending and Forming
- Article
Ever wonder why one out of every 500 or so of your deep-drawn or stretched parts splits? Why you can’t make a part consistently? The answer lies in the variables of these operations—variables all metal formers must deal with.

DIEVESTIGATION: Important considerations when designing deep-drawn parts
- By Art Hedrick
- Jun 16, 2010
- Bending and Forming
- Article
What is deep drawing? What part parameters require the process? What must you consider when designing a deep-drawn part, and when should you consider an alternate process, such as spinning?

DIEVESTIGATION: Draw or stretch? That is the question
- By Art Hedrick
- Apr 13, 2010
- Bending and Forming
- Article
When designing a part, you must decide which is the best way to form it. Should you draw it or stretch it? That depends on several factors, including forming depth.

Preventing oil canning problems
- By Art Hedrick
- Mar 9, 2010
- Bending and Forming
- Article
Oil canning cannot be cured by coining, beating, or reshaping the metal. Instead, it must be prevented by ensuring the sidewalls are not subjected to radial compression.
