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

CLAMPING SYSTEM

  • SK Series adopts outwards toggle and excellent design ideal . with quite large bar space between four column. Which is required by different industries.

     

  • Super large open stroke is 10%-20% bigger than normal one.  More suitable for deep cavity product

     

  • QT500-7 Mold board is much strong for long time service .

     

  • Adopting gear-adjusting ring with high-precision, large-scale transfer and compact structure to facilitate customer adjusting the mold thickness
