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 and integrally hardened by special process. Overall hardness reaches 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 ion spray weld. Surface hardness around HRC60°. Suitable for transparent products and engineering materials like PA6, PA66 with fiber.
Electroplating Screw: SACM645 and 38CrMoAlA base materials with hard chromium, nickel, titanium electroplating. Hardness around HRC60°. Suitable for PC, PMMA, PET transparent materials and corrosive U-PVC materials.
Stainless Steel Screw: 9Cr18MoV special stainless tool steel with overall quenching + hardening. Overall hardness around HRC55°.
SKD61 Screw: Hitachi SKD61 material with special processing for good toughness and strong torsion resistance.
Ordinary Nitrided Screw: SACM645 and 38CrMoAlA base material with special process. Nitride depth 0.5-0.8mm, overall hardness HV980~1080°. Suitable for PP, ABS, PS, AS, PVC and other ordinary plastics.

Injection Molding Machine Screw Segmentation

The screw of an injection molding machine is generally divided into feeding section, compression section, and homogenizing section (metering section). Different screws have varying proportions, screw groove depths, and bottom diameter transition forms.

Feeding Section: Fixed screw groove depth 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 for melting, mixing, shearing compression and pressurized exhaust. Plastic completely dissolves here with volume shrinkage. Compression ratio design is critical.
Homogenizing Section: Fixed screw groove depth for mixing, melt transportation, and metering. Provides sufficient pressure to maintain uniform melt temperature and stable flow rate.
