The invention relates to the technical field of plastic film plating, and discloses a process for magnetron sputtering film plating on the surfaces of plastic parts. The process comprises the steps of(1) pretreatment of the plastic parts, (2) magnetron sputtering film plating of the plastic parts and (3) aftertreatment of the plastic parts, wherein the steps of pretreatment of the plastic parts,magnetron sputtering film plating of the plastic parts and aftertreatment of the plastic parts are all performed on the same magnetron sputtering vacuum film plating machine; the magnetron sputteringvacuum film plating machine comprises a vacuum cavity; and the vacuum cavity is provided with a heating device for preheating the plastic parts, a medium-frequency ion source module for vacuum plasmacleaning or surface modification of the surfaces of the plastic parts, a twin rotating magnetron target for magnetron sputtering film plating of the plastic parts, and an evaporation module for evaporation. The process overcomes the defects in a traditional plastic part surface spraying process, increases the adhesion of film layers of the plastic parts after film plating, and improves the film plating quality.

Description

technical field [0001] The invention relates to the technical field of plastic film coating, in particular to a process for magnetron sputtering film coating on the surface of plastic parts. Background technique [0002] Most of the traditional surface spraying process of plastic parts will directly involve environmental protection issues. In addition, the surface moisture after plastic molding and dust problems due to electrostatic adsorption will directly affect the quality of the film layer. [0003] Therefore, it is necessary to develop a new coating process for plastic parts to solve the above problems. Ion implantation technology is a major research direction, such as low-temperature magnetron sputtering coating technology (which uses the interaction of magnetic field and electric field to control the directional movement of electrons, and makes electrons hit argon gas to generate ions, and then the argon ions bombard the target material, so that sputtering occurs on ...
