Important factors in the technology of zinc alloy die-casting

Today, Fu Shuai Xiaobian explains the important factors of zinc alloy die-casting technology:Zinc alloy die-casting parts will be widely used in aviation, aerospace, car, machinery and other occupations due to their excellent density, high specific strength and corrosion resistance. Praised by customers. Especially in the car industry, in order to reduce the fuel consumption and improve the power utilization rate, the replacement of steel and aluminum castings with aluminum and nickel alloy castings is a long-term development trend. In the meantime, it focuses on the treatment of non-polluting, high-efficiency, simple and concise technology, metamorphism technology, grain refinement technology and rapid detection technology before furnace.

In order to further utilize the material's potential and maximize the potential of the material, high-quality aluminum alloy materials can be developed, especially aluminum castings can meet the functional requirements of different working conditions; strengthen the research of aluminum alloy smelting process, continue aluminum alloy die-casting and kneading casting process and Development and research of related technologies to improve the development of aluminum alloy smelting equipment and related technologies and processes.

Zinc alloy die-casting is the process of applying a thin layer of other metals or alloys on some metal surfaces by electrolysis. It is a process of applying a metal film to the surface of metal or other materials by electrolysis. Corrosion, improve wear resistance, electrical conductivity, reflective properties and enhance beauty.

  Elements of electroplating:

  1. Cathode: The object to be plated refers to various connector terminals.

  2. Anode: If it is a soluble anode, it is intended to be metallized. If it is not a soluble anode, most of it is a precious metal (platinum, yttrium oxide).

  3. Electroplating solution: Contains electroplating solution to be plated with metal ions.

  4. Electroplating tank: Acceptable, storage tank for electroplating solution, generally considering strength, corrosion resistance, temperature resistance and other factors.

  5. Rectifier: A device that supplies DC power.

  The purpose of electroplating: In addition to the requirements of electroplating, electroplating has different purposes depending on various plating needs.

  1. Copper plating: used for bottoming, to improve the adhesion of the plating layer, and to resist the dry.

  2. Nickel plating: use the bottom or the appearance to improve the resistance and wear resistance. (In the process, the chemical nickel is the wear-resistant chrome in the modern process.)

  3. Gold plating: Improve the conductive contact resistance and improve signal transmission.

  4. Palladium-plated nickel: Improve the conductive contact resistance, improve signal transmission, and wear resistance is better than Jinjia. 5. Tin-plated lead: Improve the welding ability, and be replaced by other substitutes (because lead is mostly changed to bright tin and matte tin).
