Plastic pipe production line groove marks of the solution: adjust the angle of the nozzle in the vacuum sizing box, so that the pipe cooling average; check the sizing set, cutting machine, molds and other hardware can there be burrs, debris, etc.; the amount of water request balance;

Plastic pipe production line outer surface roughness of the solution: adjust the calibrating set of water inlet flow; adjust the process temperature: reduce the cooling water temperature (PE pipe best cooling water temperature of 20-25 ℃); check whether the water line is clogged or water pressure is insufficient; check the barrel, the head, and other heating ring is damaged; consult the supplier of raw materials, the raw material parameters of this batch; check the mold core temperature, if higher than the temperature of the mold section, reduce core temperature; clean the mold;

(1) Take a sample and step on the edge of the plastic pipe production line pipe to see if it can be cracked or the elongation at break after cracking.

(2) Look at the surface whiteness and finish.

(3) It is very troublesome in terms of weather resistance. The direct way is to put it in a place with high temperature and strong light for a few days to see the rate of change of the surface, but it is a waste of time.

(4) Take a sample and put it down. The ones that break easily are usually high calcium products. Of course, plastic pipe production line can meet your requirements and the price is right.
