Magnetron sputtering coating machine for plastic disposable cutleries

Short Description:

Magnetron sputtering is a widely used thin film deposition technology at present. With the continuous development of sputtering technology and the exploration of new functional films, the application of magnetron sputtering has been extended to many fields of production and scientific research. As a non-thermal coating technology in the field of microelectronics, it is mainly used in chemical vapor deposition (CVD) or metal organic chemical vapor deposition (MOCVD) to deposit thin films of materials that are difficult to grow and unsuitable, and can obtain very uniform thin films in large areas.

Advantages of sputter coating

  • First, the range of plating materials is wide.
  • Unlike evaporation coating, which is limited by the melting point and can only use the coating material with relatively low melting point, sputtering film is sputtered by high-speed bombardment of argon ions, and almost all solid substances can become the coating material.
  • Second, the film thickness has good stability.
  • Because the thickness of the sputtering coating layer has a very large relationship with the target current and the discharge current, the higher the current, the greater the sputtering efficiency, and in the same time, the thickness of the coating layer is relatively large. Because as long as the current value is well controlled, it can be plated as thin and as thick as you want within the allowable range. And as long as the current is well controlled, no matter how many times the plating is repeated, the thickness of the film will not change, which also shows its stability.
  • Thirdly, the binding force of the film is strong.
  • In that sputter process, a part of electron can impact the surface of a base material to activate surface atoms and generate a cleaning effect, the energy obtained by sputtering the plate material is 1 to 2 orders of magnitude higher than the energy obtained by evaporation, and when the atoms of the plating material with such high energy impact the surface of the base material, more energy can be transferred to the base material to generate more heat energy, The atoms activated by the electrons are accelerated to move and are mutually fused with part of the plating material atoms earlier,
  • The atoms of other plating materials are successively deposited to form a film, thereby strengthening the bonding force between the film layer and the substrate.
  • The reason why magnetron sputtering is recommended for coating plastic disposable tableware is that stainless steel can be used as the raw material for coating. Compared with vacuum resistance evaporation coating, which uses aluminum as raw material, magnetron sputtering coating is healthier and can pass the FDA standard certification for tableware.
