Castings are parts that are primarily used to manufacture a wide variety of industrial equipment, electronics, vehicles, aerospace engineering, and other major industrial products. Castings not only in plastics and rubber have some not easy to achieve the type of structure, but also in certain reaction conditions, aluminum, zinc, copper and other alloy products can be created with other forging process is different from the superior performance.

There are many factors that make casting surface treatment good, including the common ones: casting surface has out of air holes, loose and other uneven phenomena, surface roughness greatly reduces the quality of the surface coating; casting forging will have a certain state of rust, according to the spraying will cause secondary pollution; casting surface will have grease, dust and other stains. If not cleaned, after spraying can not achieve the actual effect of the purpose. Generally speaking, better surface treatment of castings needs to overcome these shortcomings.

At the level of spraying, castings with a high success rate of both package coating (topcoat) also includes passivation fluid, topcoat and other architectural coatings, especially spray paint drying technology, the coating can be changed from liquid to solid, can effectively avoid the surface spraying failure due to weathering layer and corrosion, reduce the frequency of coating and spraying corrosion concerns.

Aluminum immersion These early treatment processes reduce the corrosive effects of spraying and ensure a clean casting surface. However, these techniques also have some adverse effects. For example, dipping aluminum can reduce the adhesion of surface spraying, and surface additives can seriously affect the performance and material density of castings. Therefore, when choosing the early treatment process, it needs to be improved and selected according to the actual situation.

In order to achieve good results, techniques to improve early solutions and the use of sustainable coatings have become an indispensable stage in the coating technology of most companies. In order to ensure the quality, smoothness and stability of the coating, the use of this high-quality surface coating technology necessitates a more detailed analysis and manipulation of the data.
