vacuum pump vacuum system for Vacuum coating machine

Provide equipment and vacuum coating process for 3D parts used in automotive lamp or interior lighting industry. Such as headlights and taillights, rearview mirrors, interior lighting, etc. Reflective coating and hydrophobic coating (lotus effect) process are typically used in automotive headlights, taillights and interior lighting.
Plasma enhanced chemical vapor deposition (PECVD) is used for surface coating corrosion protection of reflective and decorative metal layers with combination of sputtering, thermal evaporation. Further application is through reactive magnetron sputtering, transparent layer surface engineering, such as wipe layer and easy to clean layer (with lotus effect), layer stack is the highest reflectivity of automobile rearview mirror and silver layer stack.
According to the type of vacuum chamber, the vacuum coating equipment of automatic lamp produced by our company can be divided into horizontal and vertical type. The main functions of the equipment include: high-pressure ion bombardment, one-time aluminum plating in the vacuum chamber and extra hard protective film (SIO). The superhard protective film improves the anti nitriding ability of the aluminum layer and keeps the long-term high reflectivity of the aluminum layer. The reflective film of the automobile lamps and lanterns has reached the national standard of automobile lamps and lanterns, and passed the experiments of acid resistance, alkali resistance and salt resistance. The equipment adopts computer to control and monitor the operation status and coating process of the equipment. It improves work efficiency, ensures the stability and consistency of product quality, and reduces the influence of human factors.
Coating machine (for lamp coating, in vacuum environment, evaporated aluminum wire covers the plastic surface with aluminum)
The reflective coating of automobile headlights and taillights made by injection molding in plastic mold is realized by Al (aluminum) with reflectivity of 90% and Ag (silver) with reflectivity of 95% – 98%. The reflective coating of vacuum equipment exceeds the specifications of all headlights, greatly exceeds the standard of NaOH test for 10 minutes in automobile industry. Our system is designed to have very fast work Cycle, can cooperate with injection molding machine production line operation. The following are four steps of high-speed, high-quality automobile lighting coating process:
