INJECTION SYSTEM 

  • The enhanced double-cylinder dual-extruding enjection structure will produce a lower back pressure in oil return during ejection. have a quicker injection speed and longer service life

     

  • The dual linear-guide , double displacement balanced stand can improve machine barrel accuracy

     

  • Precise screw design will dramatically improve the injection accuracy and effectively reduce the defective rate.  (38/42 Crmoal)

     

  • The optioncal pneumatic nozzle imported with orginal package has a flexible switch device and reliable seal

     

  • The cylinder with thicker wall and a high power heater can ensure a high plasticizing efficiency
