Product Overview
The screw is the main core component of the injection molding machine. The quality of the screw determines the quality of the product.
The plasticizing screw of the injection molding machine has the functions of conveying, melting, mixing, compressing, metering and exhausting, and is a key factor affecting the quality of plasticizing.
Injection Molding Machine Screw Material Classification
- HPT Fully Hardened Powder Alloy Screw: Made of tungsten-cobalt powder alloy tool steel with overall hardness of HRC65°. Suitable for transparent products, precision products, and high-temperature corrosive plastics like LCP, PES, PPA with fiber.
- Double Alloy Screw: Uses SACM645 and 38CrMoAlA base material with tungsten carbide nickel-based alloy spray weld. Surface hardness HRC60°. Suitable for transparent products and engineering materials like PA6, PA66 with fiber.
- 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 materials.
- Stainless Steel Screw: Made from 9Cr18MoV special stainless tool steel with overall quenching and hardening. Overall hardness HRC55°.
- SKD61 Screw: Made of Hitachi SKD61 material with special processing for excellent toughness and torsion resistance.
- Ordinary Nitrided Screw: Uses SACM645 and 38CrMoAlA base material with nitride layer depth 0.5-0.8mm and hardness HV980~1080°. Suitable for ordinary plastics like PP, ABS, PS, AS, PVC.
Injection Molding Machine Screw Segmentation
Feeding Section
Fixed screw groove depth section responsible for preheating, conveying and pushing plastic solids. Ensures plastic begins melting at the end of the feed section.
Compression Section
Tapering screw 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.
Homogenization Section
Fixed screw groove depth section for mixing, melt transportation, and metering. Provides sufficient pressure to maintain uniform melt temperature and stabilize plastic flow rate.
