Fixed groove depth design for preheating, conveying, and pushing plastic solids. Ensures plastic begins melting at section end.
Tapering screw groove depth for melting, mixing, shearing compression, and pressurized exhaust.
Fixed groove depth for mixing, melt transportation, and metering. Maintains uniform temperature and stable flow.
Advanced processing methods including vacuum nitriding, high frequency quenching, alloy spraying, and electroplating hard chromium layer. Quality indicators include 72H conditioning time, HB260-290 tempering hardness, and 168H gas vacuum nitriding time.
1-year warranty included. All products securely packaged in wooden boxes for international shipping protection.
