Screw head group 2

Nitriding screw: Made of Fushun material, the special screw and sol cylinder required for injection molding machines, extruders, rubber machines and other special products have been redesigned and manufactured to ensure that end users improve product quality while reducing production costs and creating greater value.

High temperature resistance below 350 degrees Celsius

Depth of nitride layer: 0.5-0.8mm

Nitriding hardness: HRC50-53 degrees

Surface roughness: Ra0.4um

Screw straightness: 0.015mm/1000mm

After nitriding, the surface is plated with hard chromium. Hardness: chromium plating thickness: 0.03-0.08mm

Applicable plastic range: injection molding of various plastics such as PP, PE, PVC, ABS, PBT, PET, PC, PA, PPS, acrylic, electric wood powder, etc.

Stainless steel screw: Stainless steel screw is made of 9Cr18MoV stainless steel material, which has undergone overall quenching treatment and is particularly suitable for processing PC, PMMA, PET transparent products, as well as corrosion-resistant U-PAV, ABS, PP fire-resistant plastics. Completely solving the problem of chrome plated screws often peeling off the chrome layer for end users, while fully ensuring the environmental protection requirements of the product, it is your ideal helper.

Overall hardness: HRC55 ° -58 °

Depth of nitride layer: 0.5-1.0mm

Nitriding hardness: HRC48 degrees -50 degrees

Surface roughness: Ra0.4um

Double alloy screw: The double alloy contains 25% tungsten carbide content (nickel, chromium, carbon, tungsten, cobalt), and can withstand high temperatures below 550 degrees Celsius. The screw is fully coated with alloy with a thickness of 1.5-1.8mm, with an overall hardness of HRC58-60 degrees and a smoothness of Ra0.4um; The barrel is embedded with double alloy, with an alloy layer of 3.0-4.0mm, using engineering materials+30% fiberglass;

Full hard screw: wear-resistant, corrosion-resistant, suitable for high wear product processing requirements.

Material and process: Imported from Japan SKD61SKH-9 (YXMI high-speed steel) using integral quenching and secondary tempering process. Effective length: 4000mm

Overall hardness: HRC62 ° -68 °

Usage differentiation: injection molding machine/electric wood machine

Processing size: minimum diameter of Ø 14mm

Maximum diameter of 120mm

Applicable plastics: LCP, PBT, PET, PPC, PPS, PAR, etc., with the addition of more than 30% glass fiber or other additives such as magnetic powder, ceramic powder, aluminum magnesium powder, iron powder and other engineering plastics
