Stainless Steel Screw
9Cr18MoV special stainless tool steel with overall hardness HRC55°.
SKD61 Screw
Hitachi SKD61 material with excellent toughness and torsion resistance.
Ordinary Nitrided Screw
Base materials SACM645 and 38CrMoAlA with nitride depth 0.5-0.8mm and hardness HV980~1080°, designed for processing PP, ABS, PS, AS, PVC and other standard plastics.
Screw Segment Functions
Feeding Section
Fixed groove depth section responsible for preheating, conveying, and pushing plastic solids, ensuring melting begins by section end.
Compression Section
Tapering groove depth section handling melting, mixing, shearing compression, and pressurized exhaust of plastic materials.
Homogenization Section
Fixed groove depth section providing mixing, melt transportation, metering, and maintaining consistent melt temperature and flow stability.
