The production process of PA sheet extruder is basically the same as that of our ordinary sheet. The machine includes extruder, mold, cooling bracket, traction machine, winder. PA sheet has higher requirements for machine. The screw and barrel are both made of alloy steel, which requires us to control the temperature more accurately. Too high or too low will not produce qualified products.
