Bimetallic Screw Barrel For Plastic Extruder Machine

1. Descriptions

Twin screw extruder replacement parts in segment design wear-resistant material
Screw kneading block built on modular principle allows various L/D ratio of screw easily be changed to suit different material.
Screw component made of W6Mo5Cr4V2 (it's a kind of high-speed too-steel), the hardness of screw elements is HRC58-62, and able to be changed according to process requirements.

Screw Process:

Blanking ->Punching ->Rough turning ->Hardening & Tempering ->Finish turning ->Rough Milling ->Finish Milling ->Make grooves for bimetallic ->Bimetallic by PTA ->Rough Grinding ->Rough polishing ->Make splines or Keys ->Nitriding ->Finish Grinding ->Polishing ->Packing & Delivery

Barrel Process:

Blanking ->Punching ->Rough turning ->Rough Boring ->Hardening&Tempering ->Finish Boring(0.4-0.8mm) ->Make grooves for bimetallic ->Bimetallic by PTA ->Finish Grinding ->Finish turning ->Milling the feeding hole & exhausting holes ->Nitriding ->Make other small holes,thermometer hole,location hole->Grinding surface of feeding hole & exhausting hole ->Polishing ->Packing & Delivery
