Product Overview
The screw is the main core component of the injection molding machine. The quality of the screw determines the quality of the final product. The plasticizing screw of the injection molding machine has the functions of conveying, melting, mixing, compressing, metering and exhausting, making it a key factor affecting the quality of plasticizing.
Screw Material Classification
- HPT Fully Hardened Powder Alloy Screw: Made of tungsten-cobalt powder alloy tool steel with overall hardening. Hardness: HRC65°. Suitable for transparent products, precision products, and high-temperature corrosive plastics like LCP, PES, PPA with fiber.
- Double Alloy Screw: Base material SACM645 and 38CrMoAlA with tungsten carbide nickel-based alloy spray. Hardness: HRC60°. Suitable for transparent products and engineering materials like PA6, PA66 with fiber.
- Electroplating Screw: Base material SACM645 and 38CrMoAlA with hard chromium, nickel, or titanium plating. Hardness: HRC60°. Suitable for PC, PMMA, PET transparent materials and corrosive U-PVC plastics.
- Stainless Steel Screw: Material 9Cr18MoV stainless tool steel with overall hardening. Hardness: HRC55°.
- SKD61 Screw: Made of Hitachi SKD61 material with special processing for enhanced toughness and torsion resistance.
- Ordinary Nitrided Screw: Base material SACM645 and 38CrMoAlA with nitride layer depth 0.5-0.8mm. Hardness: HV980~1080°. Suitable for ordinary plastics like PP, ABS, PS, AS, PVC.
Screw Segment Functions
Injection Molding Machine Screw Feeding Section
Fixed groove depth section responsible for preheating, conveying and pushing plastic solids. Ensures plastic begins melting at the end of the feed section.
Injection Molding Machine Screw Compression Section
Tapering groove depth section for melting, mixing, shearing compression and pressurized exhaust of plastic raw materials. Plastic completely dissolves here with volume shrinkage. Compression ratio design is critical.
Injection Molding Machine Screw Homogenization Section
Fixed groove depth section for mixing, melt transportation, and metering. Provides sufficient pressure to maintain uniform melt temperature and stabilize plastic flow rate.
