R&D Update: Multipoint-control die cushion systems for stamping complex parts - Part II

November 7, 2006 | By Taylan Altan, Ph.D.

In deep drawing of complex, asymmetrical parts such as stainless steel kitchen sinks, blank holder force (BHF) needs to be controlled locally to regulate the flow of the sheet metal. An MPC blank holder system allows this control by placing individually programmable cushion pins around the blank perimeter, with an appropriate BHF selected at each pin location.

Ask the Stamping Expert: Overcoming deformity by design

October 10, 2006 | By Thomas Vacca

Achieving typical goals in stamping, such as zero development and fewer labor requirements, is made easier when the progressive die strip is kept level through the entire progression. Keeping the strip level can eliminate wave problems caused by incorrect pilot/lifter use occurring in punch forming.
