Guangdong alloy steel castingCompared with the traditional casting process, fine casting can obtain relatively accurate shapes and higher casting accuracy. The so-called fine casting process is simply to use fusible materials to make a fusible model, apply several layers of special refractory coatings on it, dry and harden to form an integral shell, and then use steam or hot water to mold it. Melt the model in the shell, then put the shell in the sand box, fill with dry sand around it, and finally put the mold in the roasting furnace for high-temperature roasting. After the mould or shell is roasted, it is poured and melted. Metal and get castings.

Lost-wax fine casting is now called investment fine casting. It is a fine casting process with little or no cutting. It is an excellent process technology in the fine casting profession and is widely used. It is not only suitable for fine casting of various types and alloys, but also produces castings with higher dimensional accuracy and surface quality than other fine casting methods, and even other fine casting methods are difficult to cast, high temperature, and difficult to cast. The processed castings can be cast by fine investment casting.

More and more mechanical products are selected finelyGuangdong carbon steel casting, Mainly inseparable from the two advantages of fine casting:

1. Fine casting makes messy castings of various alloys, especially capable of fine casting high-temperature alloy castings. For example, the blade of a jet engine, its streamlined profile and cooling cavity, can hardly be formed by machining technology. The use of fine casting technology can not only achieve mass production, but also ensure the consistency of castings, and avoid the stress concentration of residual knife marks after machining.

2. Fine casting. Because investment castings have high dimensional accuracy and surface finish, the machining work can be reduced, just leave a small amount of machining allowance on the parts that require higher parts, and even some castings only need to be polished, Polishing allowance can be used without mechanical processing. It can be seen that the use of fine casting methods can save a lot of machine tool equipment and processing man-hours, and greatly saveGuangdong Stainless Steel CastingMetal raw materials.
