                                                                     The coatings of aluminum casting manufacturers give the appearance a beautiful appearance, and can also isolate the surface of the aluminum casting from the outside world. In the casting process of aluminum casting manufacturers, the coating plays an important role, not only to make the appearance beautiful, but also to make the surface of the aluminum casting isolated from the outside. In the aluminum casting process, the coating is also applied and applied to the surface of the aluminum casting manufacturer to make it better. However, this influence is also related to aluminum castings. Under the excellent coating and reasonable coating process, the aluminum casting process will change greatly. Under normal circumstances, most of the coatings used in aluminum castings are graphite powder. Since graphite powder has good releasability, it will produce carbon monoxide gas and bright carbon film in the

                                        Casting temperature and mechanical properties of stainless steel precision casting Stainless steel precision casting is made in the process of making it because of the small size of the transition zone, which will make it have good mechanical properties. Stainless steel precision casting can effectively meet the fluidity and the formation of bright crystals to a certain extent. The temperature is 715~740 ° C. The stainless steel precision cast round ingot has a relatively low crack tendency, so that it can be effectively guaranteed to a certain extent that its alloy has its good exhaust gas filling ability, and can effectively create its sequence close condition when used. The density can be effectively increased, and the casting temperature is generally relatively high. The manufacturing temperature of stainless steel precision casting can effectively ensure that the melt has good fluidity during the transfer process, a

Generally, a sand mold or a metal mold is used to pour aluminum or aluminum alloy heated to a liquid state into a cavity, and the obtained aluminum parts or aluminum alloy parts of various shapes and sizes are generally referred to as aluminum die castings. Aluminum casting is a kind of pressure casting part. It is a pressure casting mechanical die casting machine with a mold. The aluminum or aluminum alloy heated to liquid is poured into the inlet of the die casting machine, and die-cast by die casting machine to cast the mold limit. Aluminum parts or aluminum alloy parts of a shape and size, such parts are often referred to as aluminum die castings. Aluminum castings are used in a wide rang

                          Aluminum castings solve various technical problems of automobile engine cylinder heads Aluminium castings are used in many parts of the car. This article focuses on the cylinder head of the car engine. It has only recently been noticed that almost all car engine cylinder heads are cast from aluminum alloy, and the cylinder head is also a typical aluminum casting. For aluminum castings, the engine cylinder head is a very important automotive component product. But it is a complex and important casting part, because many of the core components of the car engine are installed here, such as the combustion chamber, intake pipe, exhaust pipe and so on. Since the cylinder head will operate at a high temperature in the engine, and the thermal shock it is subjected to is also very large, it is easy to cause a problem of stress concentration. It is precisely because of this that the requirements for the material of the cylinder head are relatively high, and

                                                              How to aluminum castings pour? When aluminum casting pour, the over-thick sprue is prone to wrap-around pores. How do you cast aluminum castings? Let's get to know it! 1. Large aluminum castings can be poured with one or two sets of sprues. Each set of sprues consists of several thin sprues. 2. When using the semi-metal casting top injection process, it is possible to set the funnel-shaped runner in the key part when it is not convenient to set enough riser, and carry out multiple refilling as the liquid level of the runner continues to sink. Achieve full complementation. 3. For large aluminum castings with many partitions, it is important to avoid the occurrence of insufficient casting defects. The exhaust of the casting itself is also very important.
