Editor’s Note: Regular readers of this column might recognize that Mr. Cattell answered a similar question in the May/June 2010 issue of STAMPING Journal®. Since this question reflects a common concern among stampers—and is asked of Mr. Cattell quite frequently in his work—we felt it would be beneficial to address the issue again.

Q: We are getting more and more inquiries for components made of titanium. We have never worked with this material. Any advice? A: Titanium can be cold- or hot-formed on standard equipment using techniques similar to those used on stainless steels, but you need to consider two main issues: The...
Fabricating operations interested in taking on more complex projects now have additional motivation: The R&D Tax Credit is permanent and could pay off for those companies involved in solving manufacturing problems.

Four areas to consider when bending include (1) formability; (2) thickness and bend radius; (3) tensile, yield, and elongation; and (4) how to deal with bending tempered materials. This month, Steven Benson applies these to forming 6061 aluminum.
This year’s FMA Annual Meeting, held in San Diego in February, celebrated the technology companies need to compete and the worker skill shops need to sustain that success through the generations.

In the past, lighting manufacturers introduced product designs that might last 10 years. Because of the lengthy product lifetime and volumes, these manufacturers didn't think twice about relying on hard tooling. Today product designs change regularly, and the constant evolution of LED technology means a manufacturer has to react quickly. For TAMCO, Port St. Lucie, Fla., that meant it needed its own laser cutting capability.

Q: When I move a die from one press to another, the die runs fine in the first press but will not run in the second press. The presses are the same size, stroke, and speed range, although one is a few years older than the other. What can I do to ensure the die runs in both presses. A: There are...

Q: We are new to die setting. Do you have a check list that could help us with different progressive dies? Can you recommend any literature on the subject? A: First, I do not know of any comprehensive literature. Most literature tends to focus on an individual subject rather than cover the overall...

Q: I’m a diemaker for a Detroit Three automaker. We have a job on which we have to change punches halfway through the run. Changing the punches is a lengthy operation and involves quite a bit of downtime. Does anyone in the industry make an automatic or semiautomatic punch removal system that we...

Q: To improve efficiency and reduce cost in our newly acquired high-speed blanking operation, we have increased press speeds from 225 SPM to 450 SPM. After several successful months, we are experiencing a high number of new press and die problems. The presses are capable of speeds higher than 500...
