Full flow oil filtration
Imported advanced hydraulic valve
Plug-in spill valve adjust back pressure of molten material

PPR fitting Injection Molding Machine 

 

1. Clamping Unit

• 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

 

 

2. 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.

 

 

 

 

3. Hydraulic System

• High efficient proportional variable pump saves electricity by 25% - 50%.

• With full flow filtration oil circuit of high precision return oil filter, the oil filter effect is up to NAS - 7 levels. 

• Spiral flow cooler is high in heat transfer efficiency and less pressure loss.

 

 

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 is equiped.
