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,...

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...

I must get two or three calls a week from companies needing tool- and diemakers, die maintenance specialists, or die repair specialists. The demand for skilled labor has skyrocketed in the last year or so. Unfortunately, most of the time I can’t help them. The Dwindling Talent Pool...

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.

Quality Industries made a U-turn on its decision to let its stamping department stall and has reignited the department’s restart with a press retrofit, quick die change (QDC) equipment, and a new press.
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.

In a few years Performance Stamping may well be a very different company. It recently cleared away inventory to free space not for more stamping, but for metal fabrication.

Zigzag feeds are being used increasingly for some applications. Stampers can achieve multi-out results using a one-out die.
In the sheet metal forming industry, finite element (FE) simulation is an important tool for fabricators predicting metal flow, optimizing geometry, and selecting process variables before developing new dies. The accuracy of the simulation results depends highly on the accuracy of the input...

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...

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...

Kenmode Precision Metal Stamping, Algonquin, Ill., displays strong design and manufacturing skills in the creation of a cardboard catamaran for the 31st America’s Cardboard Cup Regatta at Crystal Lake, Ill., earlier this summer.
Elevated-temperature (ET) forming of aluminum can be accomplished isothermally or nonisothermally. In isothermal warm forming, the die, blank holder, and punch are heated. In nonisothermal deep drawing, the die and blank holder are heated, and the punch may or may not be cooled. The die and punch...
