Die Science: How to destroy a press

January 6, 2016

By:

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: , ,

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:

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:

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.

Servomechanical press makes foray into hot stamping

October 26, 2015

By: ,

As corporate average fuel economy (CAFE) standards require increasingly lighter vehicles, stamping manufacturers look for innovative ways, such as hot stamping, to form increasingly harder metals. Hydraulic presses have been the default technology for hot-stamping presses. Now servo-mechanical presses have entered the arena that hydraulic presses previously soloed, offering improved energy efficiency, cycle time, and reliability.

Ask the Stamping Expert: What is the best method for selectively removing burrs from stamped holes?

October 5, 2015

By:

Q: We receive high-volume, high-precision, low-cost stamped parts from a vendor. The oval-shaped parts come with burrs that we need to remove from the inner holes, but we cannot round the outside part edges. The cold-rolled steel parts have two sets of holes with different diameters stamped through...
