Plating process on plastic surface of vacuum coating equipment
Plastic surface metallized craft method for vacuum coating equipment, vacuum coating equipment plastic surface metallized craft, in our daily life, can be made of a lot of plastic and plastic products products can replace metal hardware products in many cases have USES, but people's subconscious or prefer to use a metallic products. And because of this, our vacuum coating machine manufacturers generally requires a certain surface treatment method, the plastic surface plating processing, for the plating on a layer of metal (such as aluminum, zinc, copper, silver plated, gold plated, chrome plated) processing, and so on craft.
For producers to traffic is in the hands of a professional plastic electroplating factory or vacuum plating processing factory, processing method below two kinds: traditional electroplating processing method is to use similar chemical plating and electroplating water processing method for plastic or plastic products surface treatment to metal feeling. Another is to use the vacuum evaporating &coating equipment in the condition of vacuum, the metal melts, deposition in the plastic surface formation in atomic or molecular form of 5 to 10 microns of metal film.
Vacuum coating machine vacuum metallized need to cooperate well with the primer on the surface of the plastic and the thickness of the primer is usually 10-20 microns, the main role is to prevent the plastic water, organic solvents, plasticizer and other discharge affect metal attachment. It is required that the coating has a high hardness and can be used to modify the plastic defect. It can provide a smooth and flat surface for the performance of vacuum plating, and it is attached to the plastic base and the gold-plated ones. It is usually used for polyurethane and epoxy coatings with two-component room temperature curing, amino coatings for low temperature baking and thermoplastic acrylate coatings.
Mainly refers to a kind of vacuum plating equipment must be conducted under high vacuum coating equipment, it has many kinds, including vacuum ion evaporation, magnetron sputtering coating equipment, diamond film, PVD coating and so on. The main idea of vacuum electroplating equipment is divided into evaporation and sputtering.
