High Pressure injection molding machine The HP-series are composed of machines designed for reliability, stability, and precision. For that purpose, the series’ machines offer the precise clamping unit designed to assure uniform clamp-up pressure and minimize platen deflection and deformation, and the hydraulic circuit design for the security and precision test. The development of the injection unit is fulfilled by particular consideration of precision and stability.   It includes injection choices of high-pressure/high-speed or high-pressure/low-speed, and offers Bosch P/Q proportional system. The double-fly High-efficiency screw designed for engineering plastics will increase the speed of material-charging and quality of material-mixing.
