B) Composition introduction
1, Clamping Unit
Arrange obliquely five -point and elbow type structure. Optimization design on parameter of the computer. Finite -element analysis is applied to design the plates.
The unit also functions of low pressure mold protection with extra sensitivity. Machinery,Eiectric pair of safe protection function to insure the safety.
Oil motor drive the gear to adjust mould. The moving ahead simultaneously is good, and can adjusting the mould automatically according to the pressure set up, very convenient and reliable
2, Computer Controlled
Adopt imported computer which special for injection machine .The Function is powerful and controlled by CPU ,improve the speed in control system and the alarm on over-tempreture. lmprove the working speed of machine
3, Injection Unit
Double guid ing rod supporting.Dual-cylinder balance injection system,Single-cyl inder push and draw back setting. Multi -stage pressure & speed injection, One-str ing hydraulic motor setting. Super quality steel screw stem mixed with chrome, molybdenum and aluminium and barrel disposed by nitrogen .Su itable for every kinds of plastic raw material.
4,Hydraulic Unit
Adopt imported advanced hydraulic components.
