PE plastic pipe production line when a fault occurs, will lead directly to the plastic pipe surface roughness, internal jitter ring, without vacuum phenomenon, so in a timely manner to exclude the plastic pipe production line fault, in order to improve product quality.

Plastic pipe production line failure: plastic pipe outside surface roughness

Adjust the process temperature; decreasing the temperature of the cooling water, cooling water temperature is 20 best PE to 25 DEG C; check whether there is water, water pressure is insufficient or clogging phenomenon; check cylinder, die heating ring is damaged; adjust the diameter of sets of water flow; consulting raw material suppliers, this batch of raw material parameters; check mold core temperature. If the above die section temperature, lower core temperature of mold cleaning;

Plastic pipe production line failure: plastic pipe outside the surface of the ditch marks

Adjust the set of water pressure, the water demand balance; adjust the nozzle angle of the vacuum setting box, so that the pipe cooling uniform; check the mouth mold, set the diameter, cutting machine and other hardware whether there is debris, burr, etc.;

Plastic pipe production line failure: the inner surface of the ditch marks

Check the inner tube is water, such as the water will just exit the mold of the pipe die, so that the cavity closed; reduce the internal temperature of the mold; clean up and polishing the mold;

Plastic pipe production line failure: the inner ring of the pipe

Adjust the sleeve out of the water, the water evenly; adjust two vacuum, the vacuum chamber is slightly higher than that of vacuum; check the vacuum sealing pad is too tight; check whether there is any traction machine jitter phenomenon; check the discharge is uniform;
