SUMITOMO ALL-ELECTRIC INJECTION MOLDING MACHINE for PRECISE MICRO PARTSThe most advanced technology for compact molding systems is realized
by the Sumitomo All-Electric Molding Machine for Precise Micro Parts.

Most micro parts require extremely high quality,
where product mass consistency of less than
1mg and dimension tolerance of just a few
microns. Higher yields and high productivity
with multiple cavitation are also required.
To meet these needs, Sumitomo recommends
the new SE7M, the machine dedicated forthese applications.

The Second Generation Direct Drive (DD) Mechanism

High Precision Center Press Platen (CPP)

PatentpendingStandardEquipment

The compact machine with enhanced frame rigidity has its platen parallelism improvedby 2 times that of conventional compact machines. The CPP developed for the SE-D
series has been improved to meet the size of small molds.
Analysis of mold clamp force distribution

Frame rigidity 1.5 times
higher than that ofconventional machines
The uniform distribution of the mold clamp force prevents burrs, short shots and ensuring longerservice life of molds. The platen parallelism is improved by 2 times that of conventional machines.
4Fast Cycle Mold Clamp Unit
The industry’s highest platen speed of1000mm/sec. reduces the mold opening/closing
time to less than 1 sec. at full stroke.
