Full hard screw, fully hardened screw
Japan's imports SKD61, DC53, SKH55 (YXM4 high speed steel), with the overall secondary hardening and tempering process. Particularly suitable for high-wear products processing requirements, to ensure wear resistance, corrosion product needs.
Technical indicators:
Application: injection molding machines, bakelite machines
Processing size: minimum diameter Ф14mm- maximum diameter Ф120mm
Effective length: 4000mm
Overall hardness: HRC62 ° -68 °
Applicable plastic: LCP, PBT, PET, PPC, PPS, PAR, etc., more than 30% glass fiber, or add other additives, such as magnetic powder, ceramic powder, aluminum and magnesium powder, iron and other engineering plastics.
Teflon screw
Material selection GH113 (zinc on the 3rd German steel), the special Teflon material extruded material, the higher the temperature, the better the wear resistance of the material, with other features of the screw can not compete.
EFZD entire hard screw
EFZD special materials screw, specially treated to make it a whole has a hardness, its excellent wear resistance and corrosion resistance are more than double metal screw.
