Ask the Stamping Expert: What's the best-in-class process for developing a progressive-stamping die?

March 8, 2016 | By Thomas Vacca

Q: What is the best-in-class process for developing a new progressive-stamping die? A: Many tool builders think the process of progressive-die development is undefined and difficult to predict, and therefore takes way too long. Development is costly. It ties up engineering, design, toolroom...

Ask the Stamping Expert: What type of hydraulic clamps are best for quick-change setups?

March 8, 2016 | By Thomas Vacca

Q: What type of hydraulic clamps do you use in your stamping presses for quick-change setups? A: The type of clamp is insignificant; there are many suitable brands. How you use the clamp is the important thing. Before you get into a true lean die-change system, you need to do some homework....

Ask the Stamping Expert: Should light curtains stop a press even if it is traveling up?

January 8, 2016 | By Thomas Vacca

Q: We have some manual presses set up in a single part load-and-stamp production mode. The press is equipped with light curtains. When the operator activates the press buttons, he has to wait until the tool runs through the entire press cycle before he can reach into the work area. If he tries to...

Die Science: How to destroy a press

January 6, 2016 | By Art Hedrick

It’s amazing how many stampers and tool and die shops negate the importance of the press. Shops often “maintain” a press when it stops working. In other words, they repair the press, but they don’t maintain it regularly. I could have just as easily named this article “How to select...

R&D Update: Flow stress data and FE simulation

November 30, 2015 | By Ali Fallahiarezoodar, Taylan Altan, Ph.D., Zeming Yin

Finite element (FE)-based computer software commonly is used in the sheet metal forming and stamping industry for die design and for predicting metal flow and thinning in the formed part. It is a useful tool for predicting and preventing forming defects such as fracture and wrinkling. However,...

Ask the Stamping Expert: How do I calculate press tonnage for swaging?

November 30, 2015 | By Thomas Vacca

Q: We are in the process of quoting a new job for the swaging and stamping of copper rod. To do this job, we need to buy a hydraulic press. The goal is to deform copper rods into a flat form on one of the edges. How do we calculate how much press tonnage we need? A: Obviously I would need a...

3-D transfer die simulation eliminates transfer die headaches

November 11, 2015 | By Mark Hansen

Often, transfer dies are designed, built, and installed in a press, and then stamping manufacturers discover that they have crash interference problems. Then diemakers are sent to fix the problems, but the solutions slow down productivity. Running transfer dies through simulation software first can circumvent those problems.
