Why Should We Cool The Hopper’s Base Part When Extruding LDPE Pipe?

Apr 16, 2018


There are two purposes for cooling the hopper base part during the extrusion process.

1, in order to prevent the raw material's temperature too high, it will cause uneven material and unstable extrusion.

2, in order to prevent the heat of the extrusion system from transmitting to the gearbox, it will affect the normal operation of the gearbox.
