The PPR pipe manufacturing process includes raw material mixing, single-screw extrusion, spiral die forming, and vacuum sizing. It employs a slotted feed barrel and a barrier screw design to improve plasticization, and is equipped with a secondary diversion type die and a water film sizing sleeve to achieve low-temperature, low-pressure extrusion and high-speed production.
The PPR pipe machine is equipped with a five-segment screw, a servo motor-driven traction machine, and a PLC control system to achieve closed-loop monitoring of parameters such as temperature and melt pressure. The high-speed production line reaches speeds of up to 35 m/min (for 20mm pipe), and its capacity ranges from 70-350 kg/h depending on the model. The product is economical, and the technology types are divided into semi-automatic and fully automatic. Related reports indicate that its capacity utilization and demand will continue to grow.
