Background technique

Extrusion molding is to mold the polymer melt (or viscous fluid) through a die of a certain shape under the extrusion of the extruder screw. The product is a continuous profile with a constant cross-sectional shape. During the extrusion process, After the polymer is mixed with various additives, it is sent to the extruder to be melted and further mixed evenly. It passes through a multi-hole die to form multiple strips, which are then cut into pellets. Cutting can be divided into hot pelletizing and cold cutting. In the former, after the strips leave the die, they are cooled with air or water and immediately cut off with a rotating knife. In the latter, the strips are completely cooled and then sent to the pelletizer for pelletizing.
