What may be considered a highspeed stamping operation at your company may not be considered high speed at other companies or in other industries. In the electronics, fastener and lamination industries, 500 to 1200 strokes/min. (SPM) are not uncommon. High-speed progressive dies for automotive or general-purpose stampings may run at 50 to 120 SPM, and high-speed transfer dies producing large, complex deep-drawn automotive parts may run at 15 to 40 SPM. Although it can be difficult to find agreement based on strokes-per-minute, we can generally agree that high-speed stamping operations will require special attention. For example, forming and cutting more quickly requires greater stress and increased forces that can pose significant challenges for progressive and transfer tooling. These challenges include stock feeding and scrap removal, excessive tool defections, damaging tipping-moments and increased snapthrough forces that can shock and break stamping tools and damage press equipment.
