Vacuum coating machines and sanitary ware surface treatment

Vacuum coating machines and sanitary ware surface treatment

Vacuum coating machine manufacturers: sanitary ware products most commonly used methods of surface treatment of sanitary ware products after casting or machining still need to go through polished or finished and then after the addition of various surface treatments and for a while intact.
So, our sanitary ware products which most often surface approach adopted? For different pieces of sanitary ware in the end we need to adopt a surface approach and what is the most appropriate way of it? It requires a combination of products for different substrate materials, different customer requirements, different grades of positioning, different surface treatment process under production costs, among other factors, to make the right choice.
Vacuum coating machine manufacturers: Surface treatment approach sanitary ware products industry, the most commonly used generally have the following:
1, the painting process: This is one of the most well-known approach, low cost, simple treatment process, it is by means of air pressure through the gun, uniform and finely dispersed into droplets, are applied to the surface of sanitary ware pieces a method. It can be divided into air spray, airless spray, and electrostatic spray painting and other methods. Paint, usually there is a certain toxicity, have a certain influence on the body, different brands of paint toxicity due to the different ingredients are different. Use should pay special attention to safety and to avoid inhalation and skin contact.
2, the electroplating process: electroplating process is the use of electrochemical principles to sanitary ware products covered with a layer of metal approach. In addition to copper, iron, zinc alloy, aluminum and other conductive materials, ABS plastic sanitary ware pieces can also approach to the electroplating process. It includes water and vacuum plating processing electroplating process. Generally we are talking about is the water electroplating process plating, vacuum plating and coating called.
3, the electrophoresis process: that electrophoretic paint, electrophoretic coating electrophoresis is the Yin and Yang, the role of the applied voltage, charged ions paint sanitary ware products are moved to the surface, and the basic role of the surface of the product arising from the formation of insoluble thereof, these substances which is deposited on the surface of the product.
4. Spray: plastic powder coating spray is on sanitary ware products in a surface approach. It is often said of electrostatic powder spray coating, which is the use of electrostatic generator to make plastic powder charged, adsorbed on the surface of our sanitary ware products, then baked at high temperatures, melting the powder on the surface of the adhesion of a product's surface approach.

Domestic and vacuum equipment

Domestic and vacuum equipment

Some say the most durable German vacuum equipment, vacuum equipment, the most beautiful of Japan, South Korea, the most tangled vacuum equipment, vacuum equipment China's most ugly. In fact, many people do not find the same configuration for domestic and imported products at the same price or contrast ratio, the heart inside the moon always kind of feel more round. After China became the world's factory, foreign proc...essing equipment have been in China, of course, is that they use the technology.
In fact, whether imported or domestically produced equipment at the same price will not differ too much, do not own a lot of domestic R & D capabilities, without its own core technology manufacturers, buy a different quality of different brands of vacuum equipment parts are assembled into a finished (vacuum equipment contains components), the higher the price the better part quality, cheap quality parts using vacuum equipment is relatively poor, since the parts can do the same, technology, domestic equipment how there might be a difference than abroad? Some have their own R & D capabilities of equipment manufacturers, their equipment will be developed where there are some advantages. Of course, it is undeniable that the country's own technology to be worse than in some countries, if a vacuum device all with the domestic manufacturers developed their own brand products, in terms of quality and performance, but perhaps more than Germany, Japan's machine, but it has price advantage.
Now domestic vacuum coating machine is mainly imported from Germany, Japan, Korea equipment.
Germany is relatively expensive vacuum equipment, vacuum equipment with light control Japan's slightly more expensive, with only external crystal controlled in two hundred or so, with light control, crystal controlled, the ion source of about five million. Price Korea vacuum devices with light control, crystal controlled, the ion source of nearly two-thirds of Japan around.
In fact, many foreign brands of equipment are domestic procurement of hardware, domestic brands are foreign buyers a lot of hardware equipment, vacuum equipment, the best choice is based on the production of products to select the machine, such as the election computers in general, do not buy brand machine, assembly cost maybe higher.
