Mainframe use 2 sets of dou-ble screw extruder with ad-vanced technical formula can extrude the pipe in specific gravity below 0.9, its froth spread equality and has high intensity.
Special designed mix extrude mold can produce solid wall pipe and frothed inner spiral pipe at the same machine, only to change its core is ok.
Change mold, the machine can produce anti-bacterium PVC water pipe, hollow inner spiral muffler pipe and multi-layer compound pipe, for example PVC/ABS etc
