Cross-linked PEXb Pipe Making Machine High Speed Extrusion
Below Pipe Production line is used to make cross-linked PEXb pipes. The production speed is up to 30m/min.
The extruder screw and die head are special designed as per PEX cross-linking features. The line can achieve high speed production, and also prevent over crosslinking or degeneration problem of PEX material while extrusion.
Difference with PEXa pipe, the PEXb is made using silane or moisture cure method of cross-linking. The links between molecules of HDPE form after extrusion process using a catalyst and exposing the PEX pipe to hot water or hot steam container.

PEX pipes are made of HDPE and cross linking accessories. According to the difference of techniques, it has four types, PEXa, PEXb, PEXc and PEXd. Our company provide PEXa and PEXb pipe production line. We have focused on plastic pipe extrusion technology for more than 20 years, with advanced technology and high quality.
1)The high speed PE-Xb extruder adopts special structured cross-linking reaction type screw, to realize the stability and good plasticizing quality of high speed extrusion.
2)The special designed pressure-storage reaction type die head has overcome the stress orientation of polymer molecular chain during the pipe formatting, realizing the constant pressure extrusion of the pipe. The stability of extrusion pressure is the essential condition for high speed production.
3)Vacuum calibrators are special designed multi-sheet water bath type, with our company independent intellectual property rights, which realize the even and effective calibrating & cooling effects.
4)It adopts multi-group roller clamping type belt haul-off machine, with high & stable pulling speed, which completely overcomes the vibration or slipping problem of traditional rubber block haul-off machine.
5) It adopts original imported new generation PLC control system which ensures the high speed synchronous control and reliable operating of the whole production line.
