Screw Material Classification
HPT Fully Hardened Powder Alloy Screw
Made from tungsten-cobalt powder alloy tool steel with integral hardening process. Uniform internal and external hardness of approximately HRC65°. Ideal for transparent products, precision components, and high-temperature corrosive plastics including LCP, PES, PPA with fiber additives.
Double Alloy Screw
Base materials SACM645 and 38CrMoAlA with tungsten carbide nickel-based alloy ion spray welding on crest or groove. Surface hardness approximately HRC60°. Suitable for transparent products and engineering materials like PA6, PA66 with fiber additives.
Electroplating Screw
SACM645 and 38CrMoAlA base materials with hard chromium, nickel, or titanium electroplating. Hardness approximately HRC60°. Recommended for PC, PMMA, PET transparent materials and corrosive U-PVC plastics.
Stainless Steel Screw
9Cr18MoV special stainless tool steel with overall quenching and hardening treatment. Overall hardness approximately HRC55°.
SKD61 Screw
Hitachi SKD61 material processed with specialized techniques for enhanced toughness and superior torsion resistance.
Ordinary Nitrided Screw
Base materials SACM645 and 38CrMoAlA with specialized processing. Nitride depth 0.5-0.8mm, overall hardness HV980~1080°. Designed for standard plastics including PP, ABS, PS, AS, PVC.
Screw Segment Functions
Feeding Section
Fixed screw groove depth responsible for preheating, conveying, and pushing plastic solids. Ensures plastic begins melting by the end of the feed section.
Compression Section
Tapering screw groove depth for melting, mixing, shear compression, and pressurized exhaust. Complete plastic dissolution occurs here with volume reduction. Compression ratio design is critical for performance.
Homogenizing Section
Fixed screw groove depth for mixing, melt transportation, and metering. Maintains consistent melt temperature and stable plastic flow rates under pressure.
