There are often some customers who don't know much about pvd coating machines and are more concerned about the price, so they often directly ask how much a pvd coating machine costs. In this case, I would hesitate a little and think about how to give customers a simple and quick introduction, so that customers can understand that there are many types of pvd coating machines, with different application fields, and the prices vary greatly. So this involves the classification of vacuum coating machines. Anyone who knows the vacuum coating equipment industry knows that there are many types of pvd coating machines, which can be divided according to application fields or coating processes.
According to the coating process, it can be divided into evaporation coating technology, ion coating technology and magnetron sputtering coating technology. In vacuum coating equipment, what needs to be coated is called the substrate, and the plated material is called the target. The substrate and target are in the vacuum chamber. Evaporation coating generally heats the target to evaporate the surface components in the form of atomic groups or ions, and settles on the surface of the substrate to form a thin film through the film formation process.
Ion plating technology uses a target to strike an arc, emitting atoms and argon gas molecules that are ionized into ions, which are deposited on a bias substrate to form a film layer. This is called ion plating technology. Coating equipment using ion plating technology can Become an ion coater.
For sputtering coating, the pvd coating machine can be simply understood as using electrons or high-energy laser to bombard the target, causing the surface components to be sputtered out in the form of atomic groups or ions, and finally deposited on the surface of the substrate, undergoing a film-forming process. Eventually a thin film is formed. The furnace body can choose a double-layer water-cooled structure made of stainless steel, carbon steel or their combination.
Choose different specifications and types of vacuum coating machines according to process requirements. The types include resistance evaporation vacuum coating equipment, electron beam evaporation pvd coating machine, magnetron sputtering pvd coating machine, ion plating pvd coating machine, and magnetron reactive sputtering pvd coating machine. , hollow cathode ion plating and multi-arc ion plating, etc. The clamp operation modes include rotation, revolution and revolution + rotation. Users can put forward corresponding requirements according to the size and shape of the piece. The rotation speed range and rotation accuracy: ordinary adjustable and variable frequency speed adjustment, etc.
