The injection system is equipped with large diameter logic valves and precise flow control valves,improves injection response,decreases oil pressure vibration and provides precise 4-stage shot adjustment.




Adopts high and low pressure twin pump with high performance and low noise,saves energy consumption and improves production efficiency.



Adopts automatic concentrated lubrication system ,directly sets lubrication for times of machine operation and improves service life of the machine and decrease repair.




The planetary wheel system adopts oil motor to drive the gear mould adjusting machine structure which is easy to operate ;owns intelligent automatic mould adjusting program ,precisely calculates the mould locations ,which is convenient for mould replacing and improves efficiency.

The hydraulic main system adopts double proportional control ,which is convenient for adjusting the pressure and speed of every movement in the operation .The outlay precise suction filter ensures the hydraulic system of cleanness and decreases weariness of the hydraulic components.




The hydraulic ejector is convenient for control with adjustable ejecting speed.






Appliances control:
1.Adopts precise artificial intelligent computer control,can control and supervise the data and status of every movement,which is convenient for operation and maintenace.
2.The large screen LCD monitor can realize conversion between Chinese and English.
3.Its powerful memory can store 100 sets of moulding data, such as the time,times,speed,pressure,traveling distance,mould thickness,options,etc. 
4.Has self-check and alarm functions to failures of computer hardware,and display function of mechanical failures,which is convenient for mechanical failure removal .
5.Mould closing adopts high precision E-ruler positioning test,which can control the precise distance to 0.1mm.
