Non-conductive vacuum metallization

Non-conductive vacuum metallization is a vacuum coating machine that coats the surface of the workpiece with a metal film to make the workpiece look metallic and shiny. This film, although plated from a metal material, is very thin and electrically conductive. The performance is so poor that the degree of insulation is usually applied to the plastic, because the plastic is also insulated, and some plastics can be used as a substitute for metal because of their unique properties, in some products that do not require electrical conductivity. The field plays an important role.

Since the melting point of the plastic itself is relatively low, for the metal film layer material with a relatively low melting point, a vacuum evaporation coating machine can be used for the coating, because the evaporation coating machine operates by heating the film material, and the temperature rise affects the metal. At the same time, the material also affects the plastic workpiece. The metal material commonly used in the vacuum evaporation coating machine is aluminum. For metal materials with a higher melting point than plastic, the evaporation method cannot be used, but a magnetron sputtering vacuum coating machine can be used, which operates by the principle of sputtering target ionization, and belongs to low temperature coating. The equipment does not affect the plastic, but the capital investment of the magnetron sputtering vacuum coating equipment is higher than that of the vacuum evaporation coating equipment, and the customer can select according to actual needs.

For the plastic after coating, the conductivity can be measured by a multimeter or zircon, and its resistance, RF characteristics and conventional reliability can be measured. Through these aspects, the electrical properties of the coated plastic can be obtained.

Non-conductive vacuum metallization of plastics by vacuum coating equipment is a decorative film for it. It is a production mode that many plastic manufacturers are already implementing, with the aim of improving the value of plastics.
