The PPR pipe production line uses a special PPR high-efficiency extruder with German technology. The screw adopts a barrier and mixing head structure. The barrel adopts a new slotted barrel. The plasticization and mixing effect is good, and the extrusion volume is large and very stable.
The PPR pipe extrusion machine is a spiral die head designed for PPR pipes. The die has the characteristics of low melt temperature, good mixing performance, low cavity pressure and stable production. The proprietary sizing and cooling system adopts water film lubrication and water ring cooling to meet the requirements of PPR materials and ensure the stability of the diameter and roundness of thick-walled PPR pipes produced at high speed.
The PPR pipe making machine is specially designed with a multi-stage vacuum sizing box with vacuum control to ensure the dimensional stability and roundness of the PPR pipe. The extruder and tractor are driven and controlled by the frequency converter of Taiwan TECO, which has good stability, high precision and high reliability.
