The materials used in the electroplating machine are divided into two groups, namely the primer surface coating. The requirements for these two coatings are different, for example, the requirements for the primer coating,
It is necessary to choose a good vacuum performance, a good contact performance for the plated parts and the coating layer, and strict requirements for moldability, compatibility, and application properties.
The surface coating of the electroplating machine is required to have good contact performance, compatibility, corrosion resistance, and aging resistance.
Advantages of vacuum coating machine
With the development of the times, modern people pay more and more attention to the appearance of objects. Such as our mobile phone shells, car coatings, etc., The surface of these products are covered with a thin film, which not only enhances the beauty and other functions, but also has many functions that we don't know.
For example, vacuum coating can increase the anti-oxidation and anti-aging effects of some products. This is because the film can be closely attached to the surface of the product to prevent contact with the air.
The use of vacuum coating can effectively resist corrosion, and can effectively prevent some corrosive things and objects from contacting outside, thereby greatly reducing the harm of corrosion.
High temperature resistance, some vacuum wear-resistant materials can effectively reflect some external radiation and prevent high temperature exposure.
Anti-scratch, some coating media are very thick, which can effectively prevent scratches while protecting the surface of the article from damage.
Easy to clean, the surface of the coated product is very smooth, which is more convenient when cleaning. Two forms of vacuum coating machine
There are various types of vacuum electroplating machines, including multi-arc ion vacuum coating machine, winding coating machine, resistance evaporation vacuum coating machine,
Super-hard tool coating machines and other spare parts, superb technology and new materials have greatly improved the quality of craft products.
The commonly used methods in vacuum coating are vacuum evaporation and ion sputtering, both of which can be plated into corresponding colors. Vacuum evaporation coating is more extensive, commonly used resistance heating method,
Simple and convenient, low cost, but not suitable for difficult metals and high temperature resistant dielectric materials; but as abrasion resistance, sputtering coating has a better prospect. Different sputtering technologies use different glow discharge methods,
Any substance can be sputtered, especially elements and compounds with high melting point and low vapor pressure, but the equipment is more complicated and requires high-pressure equipment. If the two sputtering methods are combined,
That is, ion plating, the film obtained in this way has strong adhesion, high deposition rate, and high film density between the film and the substrate, which greatly improves the disadvantages of their respective technologies.
