Hydrraulic 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.

Common problems and solving method of injection molding machine
Number of fronts: raw material drying and die in good state, reduce the first paragraph packing pressure and adjust the corresponding time shrink: product design has no obvious mistakes, before SP point, pressure and time on the deformation die not: phenomena of mold sticking, the deformation and deformation trend is the actual product shape, the corresponding in the arched bottom core to the low-temperature water stress mark: non pin or insert caused by loose, increase the mold temperature, adjusting the injection rate (pressure and speed coordination)
Injection molding machine, injection molding machine or injection machine. It is the main forming equipment plastic products, thermoplastic or thermosetting plastics using plastic molding into various shapes. Divided into vertical, horizontal, all electric. The function of heating plastic injection, high voltage is applied to the molten plastic, so that the injection and full of mold cavity
