We are specialized in producing conical twin screw and barrel or conical thermomental twin screw and barrel for conical extrusion, whcih apply to glass reinforced plastics, modified engineering plastics filled with calcium carbonate, U-PVC(Tubular, Sheet product), PVC rubber tube. 

As per your requirements, the screw can be made with whole alloy or partial alloy, and the barrel can be made with inner bore whole alloy or partial alloy.

Nitriding steel material:38CrMoAlA, 31CrMoV9(Abroad)

Thermomental barrel material: Base mental 38CrMoAlA, 40Cr, 4CrMo

Thermomental screw material: Base mental 38CrMoAlA, 31CrMoV9(Abroad)

As per your requirements, the screw can be made with whole alloy or partial alloy, and the barrel can be made with inner bore whole alloy or partial alloy.

Conical twin screw is different with conical single screw,  the channel depth of conical single screw is constant in the whole length, however, the channel depth of conical twin screw is upward sooth from the screw head to feeding section. Hence, we nearly only use conical twin screw.

Due to the channel depth of metering section is much deeper, short screw pitch also can realize big channel volume, lead to material can stay much longer time, so that the material can be warmed up well. What is more, the screw is compressed continuously from feeding section to compression section, so the material is compressed in every section because of the conical construction.

Short diameter conical twin screw can realize the fusant more welldistributed by enlarging the middle section and the wind land gap of metering section edge.

We adopt advanced technology at home and abroad and keep improving. In the mean time, we also repair various used screw and barrel, maintain various used machines, to make the highest value at lowest cost.

With abovetenyearexperience, we have our own professional service department, to satisfy different customers. Your inquiry will be replied soonest as we can, and we can give you an advice on choosing the machine, please give us an opportunity to cooperate with you.
