Hydraykuc System

Rexroth valves are to ensure quick response and high precision.Plus optional MOOG or Rexroth servo valve,your desire of perfect molding becomes true.

Injection Unit

The intergrated double drive cylinder injection system with symmetrical oil circuit can ensure the injection stable and precise.weldless oil circuit provides high speed and high pressure.Linear guide bearings control friction within the minimum resistance.

Direct Clamping System

Patented direct clamping system,distinguished as high pressure,efficient,and energy saving,can realize 680 mm/sec.fast mould close/open and perfect low pressure mould protection.

Platen Design

Advanced platen design,big platen space&stroke and European standard platen screw hole,can satisfy your various needs.Mininal platen distortion tolerance ensures perfect molding.
