When the pvd coating machine is coating glass, defective products are sometimes plated. One of the common undesirable phenomena is that the vacuum coating machine will drop the film when it is coating glass. Since I have been engaged in the vacuum industry, customers have asked me such questions from time to time. Today, I will give you a detailed introduction to the reasons for this situation, and what are the benefits of irregular maintenance of the machine? The reasons for glass plating in vacuum coating machine are as follows:?

1、 It is necessary to clean the surface of the parts of the vacuum coating machine, because if affected by the external environment, the vacuum system can not be used normally and can not reach a high vacuum degree. In addition, the connection and airtightness of vacuum components are affected in the presence of impurities.
2、 Contaminants and impurities are totally useless to vacuum. Multi arc ion plating can divide impurities into solid impurities, gaseous impurities and liquid impurities according to their state. They exist in the form of particles. From a chemical point of view, they can be ionic or covalent, organic or inorganic.
3、 The surface layer exposed outside is most likely to be polluted. There are many kinds of pollution situations, which are generally formed by its own operation at the beginning.
4、 Attention shall be paid to surface adsorption, chemical action, cleaning and air drying, etc. The machine may produce stains during various operation processes, which may increase surface pollutants.
5、 Attention to the maintenance and cleaning of the machine in the early stage can reduce many troubles in the later stage, prevent the occurrence of various small conditions of the sputtering coater, and improve the work efficiency. Of course, the quality of the pvd coating machine coating also plays a very important role in this process. It can maximize the stability of the vacuum system wall and other various machine accessories under different conditions.
Experienced customers know that once the equipment has problems, the production cost will increase. Therefore, the unscheduled maintenance of the pvd coating machine is particularly important. What are the benefits of unscheduled maintenance for the machine?
1、 It is conducive to energy conservation and consumption reduction. Poor operation of equipment will increase friction and energy consumption. Preventive maintenance can ensure good operation of equipment, effectively reduce energy consumption, and maintain the energy conservation effect of equipment.
2、 Reduce and avoid unplanned downtime
3、 It can reduce equipment damage and prolong service life
4、 Reduce maintenance costs
5、 Avoid and reduce quality defects and scrap in mass production
6、 Reduce the risk of environmental damage
