Colored glass magnetron sputtering coating production line for tinted glass

Introduction to the production line

1.Its core characteristics:continuity, high precision and automation.

2.It mainly consists of four parts: the substrate pretreatment unit, the vacuum coating unit, the post-treatment unit and the control system.

3.It can realize the full-process production from raw sheet glass to finished colored coated glass.

4.The core equipment:a magnetron sputtering target gun, which can be configured with different target materials (such as titanium, chromium, silicon, indium tin oxide, etc.) according to color requirements.

Core production process

The production process follows a continuous logic of "pretreatment → coating → post-treatment", with each link closely connected to ensure the quality of the film layer.

Substrate pretreatment

Cleaning: Remove oil stains, dust and oxidized impurities on the glass surface through "alkali washing → acid washing → pure water rinsing → hot air drying" to avoid affecting the adhesion of the film layer.

Preheating: Heat the cleaned glass to 50-80℃ to reduce the temperature difference between the glass and the vacuum chamber and prevent water vapor condensation during coating.

Vacuum coating

Vacuum pumping: After the glass enters the continuous vacuum chamber, it is pumped by a combination of a molecular pump and a Roots pump to quickly reach the target vacuum degree.

Magnetron sputtering: In a vacuum environment, inert gases (such as argon) are ionized to generate plasma. The plasma bombards the surface of the target material, causing the atoms/molecules of the target material to separate and deposit on the glass surface, forming multiple layers of films (usually 3-5 layers). By controlling the sputtering power and speed of different targets and adjusting the composition ratio of the film, specific colors and functions can be achieved.

Post-processing and inspection

Cooling: The coated glass enters the cooling chamber and is slowly cooled to room temperature to prevent the coating layer from cracking due to thermal stress.

Testing: The color uniformity and film thickness are tested by an online optical detector (with an accuracy of up to the nanometer level), and at the same time, the wear resistance and corrosion resistance are sampled and tested. Qualified products are wound up or cut, and unqualified products are marked and removed.
