Product Overview
The screw is the core component of injection molding machines, directly determining product quality. Our plasticizing screws perform essential functions including conveying, melting, mixing, compressing, metering, and exhausting - all critical factors affecting plasticizing quality.
Screw Material Classification
HPT Fully Hardened Powder Alloy Screw
Manufactured from tungsten-cobalt powder alloy tool steel with specialized hardening processes. Features 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
Utilizes SACM645 and 38CrMoAlA base materials with tungsten carbide nickel-based alloy ion spray welding on crests or grooves. Surface hardness around HRC60°. Suitable for transparent products and engineering materials like PA6 and PA66 with fiber reinforcement.
Electroplating Screw
Base materials of SACM645 and 38CrMoAlA 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
Constructed from 9Cr18MoV special stainless tool steel with complete quenching and hardening. Overall hardness around HRC55°.
SKD61 Screw
Manufactured from Hitachi SKD61 material using specialized processes for exceptional toughness and torsion resistance.
Ordinary Nitrided Screw
Base materials of SACM645 and 38CrMoAlA with specialized processing. Nitride depth 0.5-0.8mm with overall hardness HV980~1080°. Designed for standard plastics including PP, ABS, PS, AS, PVC.
Screw Segment Functions
Injection molding screws are typically divided into three segments with varying proportions, groove depths, and transition forms depending on application requirements.
Feeding Section
Fixed groove depth section responsible for preheating, conveying, and pushing plastic solids. Ensures plastic begins melting by the end of this segment.
Compression Section
Tapering groove depth section performing melting, mixing, shear compression, and pressurized exhaust functions. Complete plastic dissolution occurs here with volume reduction. Compression ratio design is critical for performance.
Homogenizing Section (Metering Section)
Fixed groove depth section providing mixing, melt transportation, and metering. Maintains consistent pressure for uniform melt temperature and stable plastic flow rates.
