Mitsubishi Heavy Industries, Ltd. (MHI) has developed a large 3,000 ton class clamping force electric injection
molding machines, the 3000 em and 3500 em, the first in the world. While meeting the demands for the
world's fastest high-cycle production of large plastic parts such as bumpers for automobiles, the machine is
space conservative and energy efficient by incorporating MHI's unique 2-platen type mold clamping mechanism
and hybrid electric system. Furthermore, it is equipped with a newly developed center press platen and has
electric control of the internal mold pressure waveform, thus reducing flash on products to enable burr-less
molding, contributing to a reduction in customers' running costs.
