Features of vacuum coating machine
1.The film of vacuum coating is very thin (normally 0.01-0.1um)| 2.Vacuum coating can use for many plastic, such as ABS﹑PE﹑PP﹑PVC﹑PA﹑PC﹑PMMA, etc. 3. The film forming temperature is low. In the iron and steel industry, the coating temperature of hot galvanizing is generally between 400 ℃ a...Read more -
Introduction to solar photovoltaic thin film technology
After the discovery of the photovoltaic effect in Europe in 1863, the United States made the first photovoltaic cell with (Se) in 1883. In the early days, photovoltaic cells were mainly used in aerospace, military and other fields. In the past 20 years, the sharp decline in the cost of photovolta...Read more -
Process Flow of Sputtering Coating Machine
1. Bombardment cleaning substrate 1.1) Sputtering coating machine use glow discharge to clean the substrate. That is to say, charge the argon gas into the chamber,discharge voltage is around 1000V, After turning on the power supply, a glow discharge is generated, and the substrate is cleaned by ...Read more -

Vacuum ion coating and its classification
Vacuum ion plating (ion plating for short) is a new surface treatment technology which is developed rapidly in the 1970s, which was proposed by D.M. Mattox of Somdia Company in the United States in 1963. It refers to the process of using evaporation source or sputtering target to evaporate or spu...Read more -
The optical coating machine can be used for coating multiple optical films
① Anti-reflection film. For example, cameras, slide projectors, projectors, movie projectors, telescopes, sight glasses, and single-layer MgF films coated on lenses and prisms of various optical instruments, and double-layer or multi-layer broadband antireflection films composed of SiOFrO2, AlO, ...Read more -
Characteristics of sputtering coating films
① Good controllability and repeatability of film thickness Whether the film thickness can be controlled at a predetermined value is called film thickness controllability. The required film thickness can be repeated for many times, which is called film thickness repeatability.Because the discharge...Read more -
Brief introduction of chemical vapor deposition (CVD) technology
Chemical Vapor Deposition (CVD) technology is a film-forming technology that uses heating, plasma enhancement, photo-assisted and other means to make gaseous substances produce solid films on the substrate surface through chemical reaction under normal or low pressure. Generally, the reaction in...Read more -
Factors affecting the performance of vacuum evaporation plating
1. Evaporation rate will effect on properties of evaporated coating The evaporation rate has a great influence on the deposited film. Because the coating structure formed by low deposition rate is loose and easy to produce large particle deposition, it is very safe to choose a higher evaporation ...Read more -
What are the pollution sources of vacuum coating equipment
The vacuum coating equipment is composed of many precise parts, which are made through many processes, such as welding, grinding, turning, planing, boring, milling and so on. Because of these works, the surface of equipment parts will inevitably be contaminated with some pollutants such as grease...Read more
