PVC FITTING PLASTIC INJECTION MOLDING MACHINES 
 
 
PVC SERIES 
 
 
Bona new type PVC fitting injection molding machine are specialized for different sizes of PVC fitting. Saving 30%~50% of energy by using servo motor and more device options are available to fulfill customer requirements. 
 
 
 
 
 
FEATURES 
 
 
 
 
 
Specialized PVC Process – Standard TECHMATION control system, the control procedure is special designed for PVC fitting.
 
 
 
Widened Door – Widened safe door makes easier for removal of PVC fitting .
 
 
 
PVC Screw – Specialized PVC Screw solve the problems of drawing and yellowing of PVC products effectively.
 
 
 
Air Cooling – Excellent air cooling control improve the stability of PVC heat-sensitivity molding process. 
 
 
Plasticization Precision – The charge adopts high torque and low speed motor, which improves the plasticization precision. 
 
 
Servo & Variable Drives – Servo and Variable pump are available according to every production conditions. 
 
 
Core Pulling – Standard two sets of core pulling, more sets of core pulling are available. 
 
 
Temperature Control – Solid state replays for temperature control is used to ensure that the barrel temperature is controlled within a reasonable range.
