1. Higher-effectiveness one screw extruder
—One screw is with barrier & mixing head new model barrel with slotting (channel), Equally make the security of good plasticization, large output and stable overall performance.


two. Die-Head
Die-head is mostly composed of mandril, neck mildew, spiral entire body, go over, die-head human body, bolts, and heating rings.
The within area touching with plastic resources is polished and chrome plated to make sure plastic supplies circulation effortlessly and to make sure no rusting. The uniformity of pipe wall thickness can be modified by bolts. The copper calibrating sleeve mounted in die-head is mostly utilised to awesome down the clean pipe and to calibrate the pipe outer diameter.
3. Vacuum Calibration Tank
Vacuum calibration tank is mostly composed of body, stainless metal tank, vacuum technique, spray cooling method, placement adjustment system. The vacuum pump exhausts the air from the sealed tank to pressurize the clean pipe cling to calibrating copper sleeve and to calibrate the outer diameter.  Spray nozzles spray cooling water from all directions on pipe area to amazing down the pipe immediately.

four. Caterpillar Haul-off CZPT
Haul-off device is mainly composed of driving system, caterpillar, clamping construction, modifying program, side plate and foundation bed. Haul-off caterpillars are driven by AC motor with frequency conversion control to adapt to distinct extrusion speed.
CZPT size measuring system realizes cutting at a set length.


5.  No-Dust Cutter
It adopts blade punching theory to recognize no-dust slicing. It is largely composed of slicing unit, clamping gadget, construction synchronous motion unit and frame.

six.Control system
The comprehensive line could be managed by PLC, with very good human-equipment interface, all technological parameters could be set and indicated by touching screen. Managing program can be designed according to customers’ requirements. 
7.Discharging Frame
The desk surface area is made of stainless metal. It adopts pneumatic overturn and discharging instantly.
