Some customers who are new to vacuum coating processing may worry that vacuum coating processing will cause changes in product dimensions. Will vacuum coating really cause changes in product size? Today, the editor of Senfeng Vacuum Coating will reveal it to everyone!
Vacuum coating is the process of depositing coating material onto the surface of a product in a high vacuum environment to form a thin film. Due to the relatively thin thickness of the coating, usually only a few micrometers or even thinner, for most ordinary sized products, this change can often only be detected under extremely fine measurements, and its size change can be ignored.
In practical applications, by precisely controlling the coating process parameters, the size changes can be controlled within an acceptable range to ensure that the quality and performance of the product are not affected. In short, the impact of vacuum coating on product size mainly depends on the properties of the product and the requirements of the coating, and needs to be analyzed on a case by case basis.
