Features of 280Ton PVC Injection Molding Machine

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
