Machine Brief Description

Evaporative vacuum coating machine is a highly efficient surface treatment machine specially designed to form thin films by heating evaporated materials in a high vacuum environment. The working principle is based on heating evaporation, which operates in a high vacuum and firstly heats the coated material to its melting or boiling point to evaporate it into a gas phase. The evaporated material is uniformly deposited on the surface of the substrate in a vacuum environment to form a dense thin film. Commonly used heating methods include resistance heating and induction heating to ensure the stability of the evaporation rate and the uniformity of the film layer, which is widely used in the fields of optics, electronics, decoration and so on, and can significantly enhance the performance and appearance of the substrate.

Machine Brief Description

1. High vacuum operation: Working in a high vacuum environment, significantly reduce the interference of gas molecules to ensure the quality of the film layer.
2. Flexible material selection: A variety of metal, alloy and ceramic materials can be used to adapt to different application requirements.
3. Superior performance of the film layer: The formed film layer has good adhesion, wear resistance and corrosion resistance.

Frequently Asked Questions

What is the working principle of the Evaporative Vacuum Coating Machine?

The machine operates in a high vacuum environment where it heats the coating material to its melting or boiling point. This causes the material to evaporate into a gas phase, which then deposits uniformly onto the substrate surface to form a dense thin film.

What heating methods are used in this equipment?

It commonly utilizes resistance heating and induction heating. These methods ensure the stability of the evaporation rate and the overall uniformity of the deposited film layer.

What are the primary advantages of using this coating system?

Key advantages include high vacuum operation to reduce gas interference, flexible material compatibility, superior film performance (excellent adhesion, wear, and corrosion resistance), and a mature, cost-effective, easy-to-operate technology.

Which substrate materials and coating films are compatible with this machine?

It is suitable for substrates like digital electronics covers, automobile lampshades, and plastic decorative parts. Compatible coating films include alloys such as Aluminium (Al), Indium-Tin (InSn), and Nickel-Chromium (NiCr).

How does the silicone oil protective film device benefit the production process?

The configuration allows for single-clamping to complete both the aluminium plating and the protective film plating processes. This significantly enhances the corrosion resistance of the film layer, making it ideal for automotive lampshades.

What components make up the vacuum system of the ZZM/ZZW series?

The vacuum system features high-quality configurations, selecting international or Chinese famous brand molecular pumps (or diffusion pumps), polycold systems, and mechanical pumps according to specific requirements.
