Production Flow

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
