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.

Key Features & Advantages

High vacuum operation: Working in a high vacuum environment, significantly reducing the interference of gas molecules to ensure the quality of the film layer.
Flexible material selection: A variety of metal, alloy and ceramic materials can be used to adapt to different application requirements.
Superior film performance: The formed thin film layer exhibits excellent adhesion, wear resistance, and corrosion resistance.
Mature & cost-effective: Utilizes highly reliable technology with cost-effective equipment configuration and simple operational procedures.
Silicone oil protective device: Configured to achieve single-clamping completion of both aluminium plating and protective film plating, ensuring superior corrosion resistance. Ideal for automotive lampshades.

Frequently Asked Questions

How does the evaporative vacuum coating machine work?

The machine operates in a high vacuum environment where the coating material is heated to its melting or boiling point. Once evaporated into a gas phase, the material deposits uniformly onto the surface of the substrate to form a dense thin film.

What types of substrate materials can be coated?

This system is highly compatible with substrates like digital electronics covers, automobile lamp shades, and various plastic decorative parts.

What coating materials can be used in this equipment?

It supports a flexible selection of materials, including alloys such as Aluminium (Al), Indium Tin (InSn), Nickel-Chromium (NiCr), as well as other metals and ceramic materials.

What are the advantages of the silicone oil protective film coating device?

The configuration allows for single-clamping processing, completing both the aluminium plating and the protective film plating in one cycle. This significantly improves production efficiency and the corrosion resistance of the film layer.

Can the vacuum chamber size be customized?

Yes, the chamber size is fully customizable and can be designed and manufactured based on your specific production requirements and substrate dimensions.
