Servo Control System
Close loop Control
Automatic Mold Adjustment And Resin Replace
Five Pivots Toggle
Hard Chromium Plated

1. Hydraulic System  

• Close-loop control.  

• Increase injection pressure / speed resolution rate   

• High accuracy measurement control. Reduce the standard deviation to 1/3.

• High-pressured ratio of the injection pressure. Max increase 20%

• Increase response rate

• Sustantially improve the stable control of mold opening & clamping.

 

2. Clamping Unit

• Five pivots double toggle mould clamping mechanism.

• Finite element analysis on structure, the mould board is more logical, stronger and higher fatigue resistance.

• Low pressure protection function greatly prolongs the service life of the mould.

• High precision electron meter is used to control position, the control precision is 0.1 mm.

• Mechanical, electric and hydraulic (optional) safety protection are equipped

 

3. Injection Unit  

• Superior and efficient separating screw and high mixing screw increase the range of material used, and guarantee molten material to be uniform and stable.  

• Machine above BJ400 adopts double injection shift devices to prevent injection nozzle displacement and avoid material leakage.

 4. Controller

•  It can store injection material information for 120 setsof moulds 

•  Fuzzy temperature control is use. High and low temperature deviation alarm and thermocouple disconnection inspection functions are available. 

•   Function to prevent cold material start-up. 

•   Times of forming can be matched with automatic stop function for convenient production management.  

•   Computer controlled automatic lubrication devices. 

•   Automatic mould adjustion function.

 

5. Lubrication System

• Major friction parts are equipped with lubrication points. Central oil supply system is used for hinges.

• Intelligent volumetric centralized lubricating system, controlled by computer, sends quantitatively lubricating oil to wearing points.
