The application of plastic occupies a large proportion in daily life, and people pay more and more attention to improving the performance of plastic. The coating of plastic can affect various properties of plastic. Of course, it is affected by different processes and structures in the plating process. The impact will have different performances on the performance of plastics. The following focuses on the coating process of plastic pvd coating machine.

      pvd coating machine coating is to put the pretreated plastic substrate into a vacuum chamber, evacuate the equipment to achieve a high vacuum state, and use plasma bombardment to evaporate the film layer to make the film adhere to the plastic surface. The more stable the bonding; the so-called adhesion, also known as the bonding force, is how strongly the film is bonded or attached to the substrate. There are two types of adhesion, one is the basic adhesion, and the other is the actual adhesion.
       For the coating of plastic pvd coating machine, in the industry, it is widely used in optical thin films. Optical thin film technology has developed into an independent technology. Some countries have independent research institutes and production plants. The current optical thin film technology is theoretically based. A complete system has been formed in terms of design, measurement, process, and calculation. Optical plastics are treated in the pre-coating process and use a certain energy of plasma for surface bombardment and plasma-assisted coating, which can penetrate deep into the plastic surface to form chemical bonds and improve the film. The physical bonding and chemical adsorption of the layer on the plastic substrate improves the adhesion of the film layer.
       Modern vacuum coating technology has been applied in industry for nearly half a century. plastic pvd coating machine has developed from bell-jar type equipment to box-type fully automatic equipment, and has adopted advanced testing and control technology. technology.
