MHI introduces press with lower power use

MHI Injection Molding Machinery, which sells Mitsubishi injection molding machines, announced the new MMX press, featuring Mitsubishi's smart hybrid hydraulic system, which greatly reduces power consumption.

The hybrid design features a three-phase induction motor and a variable-capacity piston pump, so the system consumes less energy than other hybrids, and up to 40 percent less power than conventional hydraulic systems, according to MHI.

A servomotor stabilizes hydraulic oil flow and pressure, to save energy. An enclosed pumping system reduces noise.

The two-platen MMX features four-point, tiebar clamping, which easily tolerates unbalanced loads. The mechanism that supports the gearing housing uses a linear rail. Hydraulic cylinders are positioned at both sides of the screw, reducing the size of the injection unit.

Also, MHI said, the machine offers fast mold open/close, fast ejector retraction, fast mold-close pressurization, and a high-capacity hydraulic pump for core-pull.

MHI is based in Bensenville, Ill.
