Fastener feeding system
PennEngineering, Danboro, Pa.

A new free DVD available from the company profiles the Pemserter In-Die Fastener Feeding System. This portable equipment enables self-clinching nuts, studs, and standoffs to be installed in assemblies during the stamping process. Working in tandem with a stamping press to feed and install fasteners, the system eliminates secondary operations typically required for fastener insertions and can boost productivity, according to the company. The four-minute DVD covers key features of the system, including fastener feeder, quick-change die tools, online installation verification using sophisticated sensors, and controls. The system can be configured for multiple or single insertions, generally matching the rate of the stamping press. The DVD, which is free, can be ordered directly at www.pemnet.com by clicking on the "Free DVD" link.
