Precious metal refining technology

R & D

    It is necessary to consider the properties of electricity, magnetism, reflection rate, external color, etc. Our Company researches and develops appropriate materials and production processes according to any specific customer’s request, such as metallic materials requiring technologies of melting, casting, forging, rolling and machining. Ceramic material may need techniques of powder grinding, hot press and sintering, hot isotropic press, sintering with oxygen-rich and forging processing. Some special alloys may need a powder spreading technique since it requires higher uniformity in gradient in order to control the micro-structure of materials, such as size of grain, control of texture and phase s to fulfill customers’ demands on products.

    Conductive paste is a customized product. It needs research and development process and designing individual formulas according to different printing parameters and firing conditions required by various customers in order to reach the mass production scale requested by the clients.

  • Research and development equipment:
    • Metal target: VIM (Vacuum Induction Melting Furnace) and forging and rolling instrument.
    • Hard-to-melt metals and ceramic target: VIGA (Vacuum Induction Gas atomization), HP (Hot press and sintering instrument), HIP (Hot Isotropic Press instrument), Sintering with oxygen-rich instrument, etc.
    • Conductive paste manufacturing equipment and the pilot production line for the solar cell is essential for developing conductive paste (Ag-Al paste) for silicon-based solar cells. All the performances of the products can be examined at any time to provide customized products swiftly and satisfy various demands. 


Production process

Target melting, casting and forging process

It basically is a production approach by utilizing a high frequency induction melting furnace for casting into ingots, then forging into target with high speed forging machine and finalizing the product according customers’ demands by the micro-computerized numerical control lathe or mill.

Major competitive leverages:

  • A completed refining system that may effectively reduce the material cost.
  • Low gas content in final product, and no impure residue.
  • High purity import raw material that may assure the sputtering effectiveness.
  • Good uniformity for the grain tissue.
  • Diversified forms for products.
Process for hot press

Ceramic and metal alloy powder put into a certain shape by a prior press process, then adopting high temperature and high pressure to refine the final product.
