Bakelite screw and the general difference between the screw injection molding machine where?
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.
What is the full-alloy screw, what are the advantages?
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
What is the double-alloy screw, what are the advantages?
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.
What is the main component of SKD61 screw?
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.
