What is double alloy barrel screw- Zhoushan Jiading Plastic Machinery Co., Ltd.

Imported tungsten carbide (Wc/Co) nickel-based alloy (Ni+B/Cr), self-fluxing alloy. Processing technology: high-speed ion spray welding double alloy technology. Film density: 98～99.9%, adhesion strength: above 10000psi. Alloy thickness: 0.8-2.5mm Surface hardness: HV1180-1480° double alloy screw (high temperature resistance, corrosion resistance, high wear resistance type)

Double alloy screw (bimetal) screw base is alloy structural steel, Jinxin double alloy screw is divided into two types:

(1) The edge-sprayed double-alloy screw means that a layer of wear-resistant and corrosion-resistant alloy is melted and sprayed on the surface of the screw edge.

(2) All-injection double-alloy screw means that a layer of wear-resistant, corrosion-resistant and high-temperature-resistant alloy is sprayed on the screw rib and screw groove as a whole;

The alloy hardness of the screw surface is higher than the hardness of the base material; the main component of the double-alloy screw is tungsten carbide (Wc/Co), nickel-based alloy (Ni+B/Cr) imported from the United States, and self-fluxing alloy;

product description

Using ion Bimetallic screw barrel spray welding double alloy process, the advantage is to improve the hardness and wear resistance, corrosion resistance and high temperature resistance of the screw surface. Jinxin screw-double alloy screw is mainly suitable for adding glass fiber plastic, VO fireproof material, PA, PC, PBT, PPO, PC+ABS and other glass fiber engineering materials, scope of application: double alloy screw is mainly suitable for adding glass fiber plastic , VO fireproof materials and, PA, PC, PBT, PPO, PC+ABS and other glass fiber engineering materials.
