Product Overview
The screw serves as the core component of injection molding machines, with its quality directly determining final product quality. 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: Tungsten-cobalt powder alloy tool steel with overall hardening to HRC65°. Ideal for transparent products, precision items, and high-temperature corrosive plastics like LCP, PES, PPA with fiber.
- Double Alloy Screw: SACM645 and 38CrMoAlA base with tungsten carbide nickel-based alloy spray welding. Surface hardness HRC60°. Suitable for transparent products and engineering materials like PA6, PA66 with fiber.
- Electroplating Screw: SACM645 and 38CrMoAlA base with hard chromium, nickel, or titanium electroplating. Hardness HRC60°. Perfect for PC, PMMA, PET transparent materials and corrosive U-PVC plastics.
- Stainless Steel Screw: 9Cr18MoV special stainless tool steel with overall quenching and hardening to HRC55°.
- SKD61 Screw: Hitachi SKD61 material with special processing for enhanced toughness and torsion resistance.
- Ordinary Nitrided Screw: SACM645 and 38CrMoAlA base with nitride layer depth 0.5-0.8mm and overall hardness HV980~1080°. Designed for standard plastics like PP, ABS, PS, AS, PVC.
Screw Segment Functions
Injection molding machine screws are typically divided into three segments: feeding section, compression section, and homogenizing section (metering section).
- Feeding Section: Fixed groove depth for preheating, conveying, and pushing plastic solids. Ensures plastic begins melting by section end.
- Compression Section: Tapering groove depth for melting, mixing, shear compression, and pressurized exhaust. Complete plastic dissolution occurs here with volume shrinkage. Compression ratio design is critical.
- Homogenizing Section: Fixed groove depth for mixing, melt transportation, and metering. Maintains consistent melt temperature and stable plastic flow rates.
