Metallic Film Reflector Coating
Silver was once the most prevalent metallic material until the mid-1930s, when it was the primary reflective film material for precision optical instruments, typically chemically plated in a liquid. The liquid chemical plating method was used to produce mirrors for use in architecture, and in thi...Read more -
Vacuum Evaporation Process
The vacuum vapor deposition process generally includes substrate surface cleaning, preparation before coating, vapor deposition, loading, after coating treatment, testing, and finished products. (1) Substrate surface cleaning. Vacuum chamber walls, substrate frame and other surface oil, rust, re...Read more -
Film Layer Evaporation Temperature and Vapor Pressure
Film layer in the evaporation source of heating evaporation can make the membrane particles in the form of atoms (or molecules) into the gas phase space. Under the high temperature of the evaporation source, the atoms or molecules on the surface of the membrane get enough energy to overcome the s...Read more -
PVD coatings: Thermal evaporation and sputtering
PVD (Physical Vapor Deposition) coatings are widely used techniques for creating thin films and surface coatings. Among the common methods, thermal evaporation and sputtering are two important PVD processes. Here’s a breakdown of each: 1. Thermal Evaporation Principle: Material is heated i...Read more -
E-beam Vacuum Voating
E-beam vacuum coating, or electron beam physical vapor deposition (EBPVD), is a process used to deposit thin films or coatings onto various surfaces. It involves using an electron beam to heat and vaporize a coating material (like metal or ceramic) in a high vacuum chamber. The vaporized material...Read more -
PVD coating technology in the mold application

Meaning of vacuum pumping
Vacuum obtaining is also known as “vacuum pumping”, which refers to the use of different vacuum pumps to remove the air inside the container, so that the pressure inside the space drops to below one atmosphere. At present, in order to get the vacuum and commonly used devices including rotary vane...Read more -
The vacuum vapor deposition process
The vacuum vapor deposition process generally includes steps such as substrate surface cleaning, preparation before coating, vapor deposition, picking up pieces, post-plating treatment, testing, and finished products. (1) Substrate surface cleaning. Vacuum chamber walls, substrate frame and other...Read more -
An Introduction to Vacuum Coating
Why Use a Vacuum? Preventing Contamination: In a vacuum, the absence of air and other gases prevents the deposition material from reacting with atmospheric gases, which could contaminate the film. Improved Adhesion: The lack of air means that the film adheres directly to the substrate without air...Read more -
Thin Film Deposition Technology
Thin film deposition is a fundamental process used in the semiconductor industry, as well as in many other areas of materials science and engineering. It involves the creation of a thin layer of material on a substrate. The deposited films can have a wide range of thicknesses, from just a few ato...Read more -
Various Optical Films Used in the Optical Industry
In the field of optics, in the optical glass or quartz surface plating a layer or several layers of different substances after the film, you can get a high reflection or non-reflective (i.e., increase the permeability of the film) or a certain proportion of the reflection or transmission of the m...Read more -
