Pores are a common phenomenon in the production process of Aluminum Casting Parts, especially in the manufacturing process of Die Casting parts and powder metallurgy, due to the residual pores, crystal shrinkage and other reasons, a large number of micropores, sand holes, cracks, etc. are inevitably formed, and microporous penetration Leakage will bring hidden dangers to the use of machinery and equipment.

Even if it is used for applications without pressure requirements, the electroplating, painting and surface treatment electroplating solution, acid solution, etc. may enter the interior of the casting, causing internal corrosion and shortening the service life of the parts. Due to the existence of micropores, the surface is sprayed and electroplated. Bubbles or bumps. However, the scrapping of Aluminum alloy castings through impregnation is almost zero, which greatly saves costs and makes full use of limited resources, and the manufactured products are more in line with standards.

The purpose and function of impregnating Aluminum Casting parts are obvious. On the one hand, through such treatment, aluminum castings can be endowed with pressure resistance, sealing, and corrosion resistance. Or non-communicating micropores, which can prevent internal corrosion.

On the other hand, it can be used as a pretreatment for synthetic treatment, filling the recessed seam, preventing discoloration, corrosion, peeling and expansion; improving cutting performance, and the impregnating liquid filled inside the metal can act as a lubricant to extend the life of the tool Extended and reduce machining costs.

At the same time, it also helps to improve the physical strength and insulation of Aluminum Alloy Investment Castings. The impregnating liquid fills and blocks the internal gaps of the micropores, reduces the physical strength, and can make the product design thinner; plugging the internal cavity can improve protection. The effective resistance value.
