Clamping Unit: 
By Computer Aided Design (CAD) clamping system, the clamp stroke and distance between tie bars have been enlarged for versatile usage. 
Machines are equipped with up-down toggle system for high speed molding. 
Linear potentiometer can reach 0.01mm high accuracy, and all position settings can be saved into the computer, suitable for high precision molding. 
Fully automatic lubrication device ensures excellent lubricating effect and assures machine's accuracy. 
Ring gear and hydraulic motor driving are for quick die height adjustment. 
Hydraulic ejector is time retaining, vibration, position retain functions, and an air blasting ejector can be added. 
Core pull and unscrewing device have multi-sequence design, suitable for all kinds of molds. 
Installed with sliding clamp system cover, easy for inspection and maintenance.

Injection Unit: 
Suitable for thermosetting plastic material, double-function for exchanging between thermo-plastic and thermosetting. 
By linear potentiometer for 0.01mm high precision position control for injection and clamping systems. 
Use of oil heating circulation and electric heating for barrel, ensures the stability of temperature control. 
Specialized screw & barrel for thermosetting, special treated steel of barrel set for anti-erosion when in use of thermosetting material.
