High Speed Injection Moulding Technology
 
 
 
   
5 POINT DOUBLE TOGGLE SYSTEM
 
 
   


INJECTION CLOSE LOOP TECHNOLOGY
 

Short Cycle times
Optimum velocity profile. Due to the electronic generation of differential values, the pump output is accurately controlled.
The closing and injection units can thus be moved in accordance with preset velocity and pressure profiles to a very high drgee of repeat accuracy. Command value-pressure Actual value-pressure Movement of injection cylinder Velocity of injection cylinder

Energy saving
No throttling losses. All actuators are directly operated. Velocity and pressure are controled directly from the pump. Compared with normal hydraulic flow control systems, energy savings of up to 20% can be made often leading to a 'Zero' requirement for cooling water.
