Low pressure molding under inside-mold pressure waveform control

Achieved stable and high-cycle molding using a molding method that controls resin pressure inside a mold in real-time extending over the entire injection process. This makes it possible to eliminate the occurrence of mold internal pressure overshoot (surge pressure), restrict the unevenness of the fill quantity (mass) to a small quantity, and obtain a molded part without burrs or shorts.
