The production line for center
hollow wall developed by Fangli by taking in the latest foreign technology can
produce quality drain tubing DIAf200-f3000.This kind of tubing has become the
mainstream of city used drain tubing and will gradually substitute the steel
tubing, cement tubing, and other plastic tubing.
This production line consists of extrusion machine for special section pipe,
melting extrusion machine, twisting machine, cutting machine and related
accessory machine. It features large output, high efficiency, steady operation,
high circular stiffness for tubing, light weight per meter, good creep resisting
performance, easy connection and economical construction.
We use specially designed high efficiency single screw extrusion machine, the
screw and machine barrel are in unique design which helps to have low energy
consumption, fine plastification and reasonable mold structure. Rotational
molding after combined feed by two machines is perfect and unique in design.
By using advanced PLC computer control system, you can convenient operation and
