Screw Material Classification

HPT Fully Hardened Powder Alloy Screw

Made of tungsten-cobalt powder alloy tool steel with integral hardening. Overall hardness reaches HRC65°. Suitable for transparent products, precision items, 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°. Ideal 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 around 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 around HRC55°.

SKD61 Screw

Hitachi SKD61 material with special processing for excellent toughness and torsion resistance.

Ordinary Nitrided Screw

SACM645 and 38CrMoAlA base material 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 groove depth section responsible for preheating, conveying, and pushing plastic solids. Ensures plastic begins melting at the end of this section.

Compression Section

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

Homogenizing Section (Metering Section)

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