Notice befor coating

Huasheng coating process needs high temperature and high vacuun enviornment, so does tools be coated. Please check followed annoucement to fulfill our PVD coating performance:

  • [ Workpiece able to be coated ] Close

    To provide perfect process for tools Huasheng needs some basic information about coating tools like substrate material, hardness and temper temperature. Here are materials can be coated:

    1. Alloy steel, HSS and stainless steel

    2. Cement carbide

    3. Titanium alloy

    4. Nickle alloy


    For chisel steel it has to be tempered twice or more over 500 degree centigrade and keep its hardness and electrical conductivity. Because whole tools would be coated inside chamber in PVD process so make sure the whole tool can meet these requirements.

  • [ Coating area ] Close
    Please note coating area of a tool with an area for clamping, it is not likely to full coating cover a whole tool. If there is somewhere should not be coated, please annoce us in advance.
  • [ Limits on tool surface ] Close

    1. Tools for coating cannot be: electroplated, nitriding, carburized, parkerising, oxidized, TD, CVD or other surface treatment.

    2. There should not be rust, corrosion, oil paint, glue on tool surface.

    3. Surface roughness: with reach requirement of using, workpiece surface should be as much as smooth, surface Ra<0.2μm is better; for special mirror plastic mold, etched die it depends on product standard.

    4. Assembling die or mosaic tool must be disassembled.

    5. Welding ool surface should be completely clean without oxidation layer or hole on top.

  • [ Package and shipping ] Close

    1. HSS and tool steel parts should be oiled before transferred.

    2. Tool should be packed individualy.

    3. After coating HSS and tool steel we will also oiled surface (except special requirement).

  • [ Dimensional accuracy ] Close

    1. Husheng PVD coating range from 0.5μm to 30μm, with precisely controlled of process.

    2. If you have high requirement of dimensional accuracy of product please leave the space and announce us in advande.

  • [ Largest coating size ] Close
    Huasheng coating has a largest area of no more than φ900*1000mm.
  • [ PVD coating limit ] Close
    PVD coating can cover complex surface, but only can coat hole with pit-depth ratio no smaller than 1:1 and with coating thickness is thinner with depth.
  • [ Recoating ] Close
    Huasheng provides decoating service for customer (except some carbide tools).
  • [ What customer should provide ] Close

    1. Materials and code of coating tools.

    2. Tempered teamperature and hardness.

    3. Note us surface needed coating.

    4. Dimensional accuracy smaller than 5μm tools need dimensional accuracy requirement.

    5. Cutting data and workpiece for us to provide perfecr coating.
