What is special casting

SpecialLost wax casting: Casting methods that use less sand or no sand, and use special process equipment for casting, such as investment casting, metal mold casting, pressure casting, low pressure casting, centrifugal casting, ceramic casting and solid casting. (Specific details are introduced in the next article)

Basic Features:

1. From the perspective of casting process, the dimensional accuracy and surface roughness of castings mainly depend on the nature of the casting mold;

2. The mechanical properties of castings under the same chemical composition mainly depend on the cooling rate. Change liquid metal filling and cooling conditions;

3. Reduce metal consumption and casting scrap rate;

4. Simplify the casting process (except investment casting), easy to realize mechanization and automation;

5. Improve working conditions and increase labor productivity.

Because of theGuangdong alloy steel castingAs the requirements for quality, casting accuracy, casting cost, and casting automation have increased, casting technology is developing towards precision, large-scale, high-quality, automation and cleanliness. For example, in recent years, my country’s The rapid development of casting technology, casting automation and casting molding simulation technology.

The molding method of pouring, injecting or sucking molten metal into a mold cavity and obtaining a blank or part with a certain shape, size and performance after solidification is called casting.

Since the casting adopts the next molding process in the liquid state, it has a wide adaptability to the type of material and the shape of the part, the size and the production batch. It is especially suitable for the gradual production of complex shapes, and the production cost is low.Guangdong carbon steel castingIt has an important position and role in mechanical manufacturing, but the characteristics of liquid forming also make casting have many shortcomings, such as gradually difficult quality control, and gradually lower mechanical properties.
