Non conductive vacuum metallization is to coat a metal film on the surface of the workpiece through a vacuum deposition device to make the workpiece look like it has the texture and luster of metal. Although the film is coated with metal materials, it is very thin and has poor conductivity, so that it is usually coated on plastic to the extent of insulation, because plastic is also insulated, and some plastics can become substitutes for metal because of their unique properties, It plays an important role in the field of products that do not require conductivity.

Due to the low melting point of plastic itself, vacuum evaporation coating equipment can be used for coating metal film materials with low melting points. The evaporation coating machine operates by heating and vaporizing the film material. Temperature rise not only affects the metal material, but also affects the plastic workpiece. The commonly used metal material for vacuum evaporation coating machine is aluminum. For metal materials whose melting point is higher than that of plastic, the evaporation method cannot be used, but the Magnetron sputtering vacuum deposition machine can be used. It is operated by the principle of sputtering target ionization, and belongs to the equipment for low-temperature coating, which does not affect the plastic. However, the capital investment of Magnetron sputtering vacuum coating machine is higher than that of vacuum evaporation coating machine, so customers can choose according to actual needs.
For the conductivity of coated plastic, we can measure its resistance, RF characteristics, and conventional reliability using a multimeter or zircon. Through these aspects, we can obtain the electrical properties of the coated plastic.
The non-conductive vacuum metallization of plastics by using vacuum coating machine is the plating of decorative films, which is a production mode that many plastic manufacturers are already implementing, with the purpose of better improving the value of plastics.
