An electromagnetically driven metalworking press
A small press operated by electromagnetic repulsion and driven by a pulse power supply was
constructed at The Ohio State University. This design that applies kinetic energy rather than
static force to do work on materials is much lighter and potentially much less expensive than
traditional hydraulic, mechanical or servo presses. Performance of the kinetic press is
compared to traditional presses in the applications of powder compaction and forming. The
results tend to indicate that modest impact speeds of 3 to 18 m/s can improve performance in
these manufacturing operations as compared to traditional low-speed machines
