PEX-AL-PEX Composite Pipe Extrusion Line


The aluminum-plastic composite pipe is five layer structure: plastic layer (can be PEX, PERT, PE, PP or PPR) - adhesive layer - aluminum layer - adhesive layer - plastic layer (can be PEX, PE or PERT). Our machine can form five layer in one step, to save machine space and increase stability, production yield can reach 98%, line speed is also higher.

In addition pipe made by one step has higher quality, as all material are extruded and integrated at one time, no need to reheat material again. In this way, adhesion between each layer is much better.

Our aluminum layer is made by ultrasonic overlap welding.
