In general, the injection molding material belongs to the [thermoplastic material] - is in the screw barrel inside the high temperature plasticization - in the mold inside the low temperature to cool down in the mold inside the high temperature solidification, forming. The biggest difference between the two is the injection molding material properties, thermosetting and thermoplastic difference, so the screw design is also based on this feature to design, Bakelite screw - small aspect ratio, low compression, no reverse ring, Meson, the use of the overall style, the general choice of material JY Yang JY wear-resistant corrosion-resistant alloy.

Full-alloy screw is the whole screw is the whole hardening alloy, screw from the inside out to the outside material and hardness are the same; Jin Yang's full-alloy screw is the main component of tungsten cobalt-based powder alloy (imported from Germany); using the whole hardening process , The advantages of both hardness and toughness (super wear-resistant, corrosion-resistant, high-speed, high temperature 600

Double alloy screw (bimetallic) screw base material for the alloy structural steel, gold foreign double-alloy screw is divided into two types: (1) edge spray double-alloy screw refers to the surface of the spirally spray welding wear-resistant corrosion-resistant alloy, (2) all-spray double-alloy screw means that the spiral edge and groove as a whole spray a layer of wear-resistant, corrosion-resistant, high temperature alloy; screw surface alloy hardness is higher than the substrate; Jin Yang's double alloy screw is the main component of the United States (Ni / B / Cr), self-fluxing alloy; the use of ion spray welding double alloy process, the advantage is to improve the hardness of the screw surface and wear, corrosion resistance, high temperature performance. Golden foreign screw - double-alloy screw is mainly applied to add glass fiber plastic, VO fire material and, PA, PC, PBT, PPO, PC + ABS and other fiberglass engineering materials.

SKD61 screw using SKD61 hot work die steel, Jinyang SKD61 screw (imported from Hitachi Metals). SDK61 alloy steel is the main component of carbon high chromium alloy tool steel quenched and tempered, quenching + overall hardening treatment. The main advantage is good toughness, with wear-resistant high temperature performance; Jin Yang screw SKD61 screw suitable for general engineering plastics production, add a small amount of filler PC, PA, POM, PBT and a small amount of glass fiber plastic.

Stainless steel screw with special stainless steel tool. The main ingredients are chromium, molybdenum, nickel, silicon, carbon. Jinyang screw - stainless steel screw for processing PC, PMMA, PET transparent material and the general level of U-PVC and other corrosive plastics.

Plating screw means the surface of the screw in a layer of electrical coating. Screw substrate optional SKD61 / SACM645 / 38CrMoAla, the surface can choose a chrome-plated, titanium, nickel. It is suitable for processing U-PVC corrosive plastics, PFA and acid corrosion materials, and PC, PMMA, PET general transparent material.

Bimetallic barrel (bimetallic), the barrel base alloy structure steel, the hole centrifugal casting 2-3mm thick alloy layer. Jinyang double alloy barrel alloy composition of tungsten carbide alloy, nickel-based alloy, cobalt-based alloy, with wear-resistant, corrosion-resistant, high temperature, high-speed high-pressure-resistant performance. POM, PBT, PEEK, halogen-free materials, magnetic powder and other special, high temperature, high corrosive plastic; and PC, PMMA transparent material.

Nitriding barrel is the most common barrel, the material composition: SACM645 alloy steel; 38CrMoAla alloy structural steel, Jinyang nitride barrel by quenching, molding, ion nitriding, stereotypes, soft nitriding (secondary nitriding) . The barrel bore surface hardness and wear resistance, Jinyang screw - nitrogen barrel for processing ordinary plastic, PP, ABS, PS, PE, EVA, PVC, PO, PU and other general plastic
