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

HYDRAULIC SYSTEM

• With international High Speed Storage motor and Hydraulic Components ensure fast , effcient and long life operation

   

• Modualr design for High-Response oil circult and hydraulic valve plate Which have a large oil circule and free of damp effectively reduce pressure loss , speed up system response ability

   

• Original germany oil pipe and seals avoid oil leak. 

ELECTRONIC CONTROL

• The whole electrionic control system is design for full electric and high speed injection molding machine

   

• Apply Up-To-Date System,  New hardware design,  intelligent interactive interface ,  A CPU for fast arithmetic speed

   

• Using EtherCAT/CAN  All-Date Communication technology Show clear iprovement in all technical indexes. Actsmore accurately in pressure and flow rate control

   

• Reserves an internet management systen and energy consumpition display which enables advantanced control modes.

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
