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 multiple functions including conveying, melting, mixing, compressing, metering and exhausting, making it a critical factor affecting plasticizing quality.
Screw Material Classification
- HPT Fully Hardened Powder Alloy Screw: Made of tungsten-cobalt powder alloy tool steel with overall hardening. 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 ion spray welding. Suitable for transparent products and engineering materials like PA6, PA66 with fiber.
- Electroplating Screw: Base materials SACM645 and 38CrMoAlA with hard chromium, nickel, or titanium electroplating. Suitable for PC, PMMA, PET transparent materials and corrosive U-PVC plastics.
- Stainless Steel Screw: 9Cr18MoV special stainless tool steel with overall quenching and hardening. Suitable for various applications requiring corrosion resistance.
- SKD61 Screw: Hitachi SKD61 material with special processing for excellent toughness and torsion resistance.
- Ordinary Nitrided Screw: Base materials SACM645 and 38CrMoAlA with nitride layer depth 0.5-0.8mm. Suitable for ordinary plastics like PP, ABS, PS, AS, PVC.
Screw Segment Functions
Feeding Section
Fixed screw groove depth responsible for preheating, conveying and pushing plastic solids. Ensures plastic begins melting at the end of this section.
Compression Section
Tapering screw groove depth for melting, mixing, shearing compression and pressurized exhaust. Plastic completely dissolves here with volume shrinkage. Compression ratio design is critical.
Homogenizing Section (Metering Section)
Fixed screw groove depth for mixing, melt transportation, and metering. Provides sufficient pressure to maintain uniform melt temperature and stable flow rate.
