Main features of the EVOH barrier pexb pipe making machine:
1)The self-developed co-extrusion die head mold which has been vertified and improved for a long period of time has many advantages, such as easy operating, each layer thickness and high accuracy of the pipe sizes.
2) The special control system and extruders that are developed based on the multi-layer co-extrusion characteristics optimally guarantees the stable running of the whole production line.
3)The high precision PLC entire line control system can ensure the responsveness, reliability and stability of the line
4)The special designed EVOH extruder is suitable for extruding EVOH oxygen barrier resin with high melt pressure, ensuring the stability of the resin's extrusion
