Product Overview
The screw is the core component of injection molding machines, with quality directly impacting final product outcomes. Our plasticizing screws perform essential functions including conveying, melting, mixing, compressing, metering, and exhausting - making them critical factors in plasticizing quality.
Screw Material Classification
HPT Fully Hardened Powder Alloy Screw
Manufactured from tungsten-cobalt powder alloy tool steel with integral hardening. Uniform internal and external hardness of HRC65° suitable for transparent products, precision components, and high-temperature corrosive plastics including LCP, PES, and PPA with fiber additives.
Double Alloy Screw
Base materials SACM645 and 38CrMoAlA with tungsten carbide nickel-based alloy ion spray welding. Surface hardness HRC60° ideal for transparent products and engineering materials like PA6 and PA66 with fiber reinforcement.
Electroplating Screw
SACM645 and 38CrMoAlA base materials with hard chromium, nickel, or titanium electroplating. Hardness HRC60° suitable for PC, PMMA, PET transparent materials and corrosive U-PVC plastics.
Stainless Steel Screw
9Cr18MoV special stainless tool steel with complete quenching and hardening. Overall hardness HRC55° for specialized applications.
SKD61 Screw
Hitachi SKD61 material processed for exceptional toughness and torsion resistance.
Ordinary Nitrided Screw
SACM645 and 38CrMoAlA base materials with nitride layer depth 0.5-0.8mm and hardness HV980~1080°. Designed for standard plastics including PP, ABS, PS, AS, and PVC.
Screw Segment Functions
Feeding Section
Fixed groove depth section responsible for preheating, conveying, and pushing plastic solids. Ensures plastic begins melting by section end.
Compression Section
Tapering groove depth design for melting, mixing, shear compression, and pressurized exhaust. Complete plastic dissolution occurs here with critical compression ratio design.
Homogenization Section
Fixed groove depth for mixing, melt transportation, and metering. Maintains consistent pressure for uniform melt temperature and stable plastic flow.
