In order to make the aluminum alloy material have high corrosion resistance, it also needs to have many advantages such as diversified colors and good surface texture, so the surface needs to be painted and decorated. In addition, spray paint on the surface of aluminum alloy is difficult to adhere to, and the phenomenon of paint drop often occurs. Aluminum alloy has low density but relatively high strength, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry.
So how should the spray paint on the surface of aluminum die-cast auto parts be handled and the problem of poor adhesion and paint drop? Many users of aluminum alloy spray paint will encounter a problem. The sprayed paint will easily fall off and the adhesion is very poor. So what is the reason? This is mainly because the surface of light metal such as aluminum alloy is extremely smooth, which is very different from steel material. Similar materials include stainless steel, aluminum plate, galvanized steel, etc. The smooth surface is difficult for ordinary paint to adhere to, so It is necessary to use Jiongsheng metal adhesion promoter to improve the adhesion performance between the substrate and the coating to solve the problem of paint falling.
Die-casting parts can be manufactured into automobile die-casting parts, automobile die-casting engine pipe fittings, die-casting air-conditioning parts, die-casting gasoline engine cylinder heads, die-casting valve rocker arms, die-casting valve seats, casting power accessories, die-casting motor end covers, die-casting shells, Die-casting pump housings, die-casting construction accessories, die-casting decorative accessories, die-casting guardrail accessories, die-casting wheels and other parts. With the continuous improvement of the development level of the domestic manufacturing equipment industry, the equipment level of the die-casting machine has also been significantly improved, and the types of parts that can be manufactured are also With continuous expansion, the precision and complexity of die-cast parts have also been greatly improved. I believe that in the near future, die-casting parts will better serve our production and life!
