Twin Screw Extruder

(1)conical twin screw extruder is efficient equipment for all kinds of PVC powder extrusion.Equipped with different screw moulds and auxiliary machine,it can produce plastic pipes, profiles, sheet, boards, granules ect.

(2) The motor is siemens,the main motor and feeding motor can respectively by means of variable frequency adjustify speed control system.

(3) In according with different requirements of the clients, we can equip the corresponding screw moulds and auxiliary machine

(4) Stable extrusion pressure, with high output, low cost, and simple production process
