Vacuum coating machine coating principle

 

Widely used production equipment vacuum coating machine products but with the development of the electronics industry, vacuum coating machine coating to continuously improve quality, making our daily contact with plated products more and more.

Vacuum coating machine coating works:

From a sort of sense, vacuum coating is also determined by the vacuum coating of oil, in a vacuum coating process, the coating of oil referred to the role and firmly bonded plated metal film parts, both effects occur in the undercoat plated parts, effect also occurs in the surface coating of plating.

1. vacuum environment
  Vacuum environment affects the results and efficiency of vacuum coating, and we all know that the vacuum coating is coated in a high vacuum degree created by vacuum pumps, the unit is represented by Pa, there are higher vacuum gas the less, the lower the impact of plating .

2. The coating process
Vacuum coating technology with advances in technology, there is a vacuum vapor deposition, magnetron sputtering, vacuum ion plating and other advanced widely used process requires the use of different products differ, depending on the circumstances need to select cost-effective products high-coating process, which directly affects the price of vacuum coating machines, and cost.

Principle to distinguish between different coating process is very large, about evaporation deposition, ion plating, sputtering of the specific methods and parameters will be described later in this article will not elaborate. Related Information: PVD coating

Vacuum coating machine is complex, understanding the principles and structure of vacuum coating machine helps to analyze and enhance everyday productivity and troubleshooting, in actual use, the machine is often prone to this kind of problems, to improve the life of the machine and productivity in principle the need for proper maintenance of the machine.

PVD Magnetron vacuum Sputtering Deposition Line for ITO Glass

  Leading-Coating vacuum coating equipments is a professional company in all kinds of coating machines which has 30 years experience in field.
  The pvd magnetron sputtering coating machine is a vacuum deposition machine line uses two industrial computers and PLC systems. The production line can dynamically display and control the whole operation process with alarm and self-protective functions. The important processing parameters with several optical inspected systems connected to the computer, so the color and thickness of the film can be automatically controlled.
ITO Glass coating line:
  This machine are available to metalize transparent electric conductive film on glass, for example, LCD, PDP display or OLED display, etc.
  Using vacuum magnetron sputtering deposition technology, with dual cathodes, MF sputtering technology and international advanced control system, it is to deposit SiO2/ITO on the float glass. All the process is automatically controlled in series.

Resistance Evaporation Coating Equipment for Plastic, Glass, Ceramic

  Resistance Evaporation Coating Equipment for Plastic, Glass, Ceramic vacuum decorative coating
   Has a reasonable structure, even film, good-quality film forming, quick pumping speed, etc.
  The high vacuum coating e​quipment adopts the resistance heating in the vacuum chamber, to melt and vaporize the metal wire (aluminum wire) cling to the resistance wire. The vaporized metal molecule deposit on the substrates, to gain the smooth film as well as high reflectivity. Thus the surface of the items can be decorated and beautified.
  Characteristic: Reasonable structure, even film, good-quality film forming, quick vacuum pump speed, the cycle of short, high efficiency and easy operation, low energy consumption and performance advantages of stability.
   Applied industry: Widely used in automotive, audio and various small appliances, computers, clocks and watches, toys, cell phones, reflective Cup, cosmetics, toys, tableware, sanitary ware, shoe heel, ABS, PS, PP, PC, PVC, PET, nylon, metal, Boli, glass, ceramics, TPU, etc.

Germany has researched low emissivity coating method for architectural glass

       

   In Germany, building adopting energy-saving low-e glass coating has been a standard practice. As Germany BINE club's latest report, Germany has developed low emissivity coating again, which opened up a broader application prospect.
  The low-e glass, also called low radiation glass, which coat layers of metal or other compound film combination on the glass surface. This kind of glass can reduce the thermal radiation from the outside in the summer, thus reduce air condition usage. In winter reduced heat transfer to outdoor, achieve the ideal energy saving effect. Low-e glass is to coat metallic film layer on the inner surface of the double layer or three layers of glass, and under the good protection, light construction structure, weather proof.
   Under the German federal economic and technical support, Bavaria applied energy research center to develop polyurethane mixed aluminum pigment particles, which meet thin film of fabric coating methods, and achieve the ideal effect of low-e glass coating.
