Application
PVC pipe is mainly used in the agricultural water supply and drainage,
water supply and drainage construction, cable supporting, thickness of
pvc plastic pipe, The lines have conical twin-screw extruder, vacuum calibration tank, haul-off machine, cutting machine, stacker or belling machine and so on.
Haul-off machine have two caterpillar, three caterpillar, and four caterpillar, six caterpillar, the cutter use knife-raised cutter or planetary cutter which support chamferring function. And the stacker take into account length,
production line is reliable performance, and high quality, we have exported to Egypt, Brazil, Syria, Uzbekistan etc.
Feature
1) Main machine uses PVC twin screw, and notch feeder with powerful water
cover cooler, which has greatly improved transmitting capability and ensured
extruding.
2) Adopting double pipe extrusion method, it can greatly increase productivity.
3) Adopting high efficiency double-cavity vacuum calibrating technology and spray-paint
cooler gullet, which improve the finished product passing rate, and meet
the requirements of high speed manufacturing. Vacuum calibrating platform and cooler
gullet are all made of stainless steel
4) Adopting multi-caterpillar haul-off, through the central motor to run all the caterpillar
to reach same height, and ensure roundness of pipes
5) Adopting fully automatic control system with high precision, reliable operation,
easy and convenient handling
6) Suitable pipe diameter: 20 - 630mm
System configuration:
(a) Feeding machine
(b) Conical twin-
screw extruder
(c) Mould
(d) Vacuum calibrating tank
(e) Hauling off machine
(f) Printing machine
(g) Pipe cutting machine
(h) Pipe pile-up frame
(i) Auxiliary machine such as mixer, water chiller,
belling machine and crushing machine.
We can make the production of different pipes with 16mm - 630mm diameter range.
