PPR pipe production process for the extrusion process, the first bucket of PPR raw materials by weight into the extruder, extruded in the extruder barrel by heating extrusion, fully plasticized from the extruder die extrusion, Into the stereotypes of Taiwan, after the stereotypes of the pipe by the traction machine, determined by the fixed length, cut by the cutting machine, pipe inspection after passing inspection. The corresponding tube is produced by injection molding.
Pipe production process: PPR raw materials → vacuum suction feeding → hopper storage → feed → extrusion → cooling stereotypes → traction → cutting → inspection → storage pipe fittings.
Production process: PPR raw materials → conveying materials → hopper storage → feed → heating and melting → extrusion injection → cooling stereotypes → open mold → inspection → storage.
Pipe extrusion parameters: (1) screw speed: 5 ~ 38r / min. (2) barrel temperature distribution: 1 ~ 2 area 180 ~ 190 ℃, 3 ~ 4 area 200 ~ 210 ℃, mold temperature 200 ℃, traction speed 2 ~ 20m / min.
Tube injection parameters: (1) barrel temperature distribution: the rear of the barrel 160 ~ 170 ℃, the middle of the barrel 200 ~ 230 ℃, the front of the barrel 180 ~ 200 ℃. (2) Nozzles: 170 to 190 ° C. (3) Mold: 40 to 80 ° C.

PPR pipe production process produced defective products, can be reused after use, which improves the utilization of raw materials, and can reduce production costs and improve economic efficiency.
