Resin is plasticated by an extruder and shaped into the form of a pipe by a die
The still soft pipe is fed into a calibrator which adjusts the dimensions of the pipe
The pipe then goes into the cooling system
After cooling, the pipe goes into the take-off system called a puller. The puller controls the speed of the extrusion line
Then the pipe is cut into a specified length by a cutter
Finally, the cut pipes are stacked (or wound up) by a stacker (or a coiler)
