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
