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 performs essential functions including conveying, melting, mixing, compressing, metering and exhausting, making it a critical factor in plasticizing quality.

Screw Material Classification

HPT Fully Hardened Powder Alloy Screw: Made of tungsten-cobalt powder alloy tool steel with overall hardening. Uniform hardness of HRC65° throughout. Suitable for transparent products, precision items, 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 weld. Surface hardness HRC60°. Ideal 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. Hardness HRC60°. 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. Overall hardness HRC55°.
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 and overall hardness HV980~1080°. Suitable for PP, ABS, PS, AS, PVC and other standard plastics.

Screw Segment Functions

Feeding Section

Fixed screw groove depth section responsible for preheating, conveying and pushing plastic solids. Ensures plastic begins melting at the end of this section.

Compression Section

Tapering screw groove depth section handling melting, mixing, shear compression and pressurized exhaust. Plastic completely dissolves here with volume shrinkage. Compression ratio design is critical.

Homogenizing Section (Metering Section)

Fixed screw groove depth section for mixing, melt transportation and metering. Provides sufficient pressure to maintain uniform melt temperature and stable plastic flow rate.
