What is the manufacturing process of Dongguan precision casting

Dongguan precision casting is to pour molten metal liquid into the mold, and obtain parts with the required shape and function through cooling and condensation. Manufacturing process. Casting is a common manufacturing method.

Advantages of Dongguan precision casting: low manufacturing cost, high process sensitivity, messy shapes and large castings, and occupy a large proportion in mechanical manufacturing, such as machine tools accounted for 60-80%, automobiles accounted for 25%, and tractors accounted for 50-60 %.

Dongguan precision casting is an ancient manufacturing method that can be traced back to 6000 years ago in our country. With the development of industrial skills, the quality of large castings directly affects the quality of products. Therefore, Dongguan precision casting occupies an important position in the machinery manufacturing industry. The development of casting technology is also very fast, especially in the late 19th century and the first half of the 20th century, many new Dongguan precision casting methods appeared, such as low pressure Dongguan precision casting, ceramic Dongguan precision casting, continuous Dongguan precision casting, etc. , Was perfected and applied in the second half of the 20th century.

With the improvement of the quality of Dongguan precision casting, the precision of Dongguan precision casting, the cost of Dongguan precision casting and the automation of Dongguan precision casting, the precision casting technology of Dongguan is developing in the direction of refinement, scale, high quality, automation and cleanliness. For example, in recent years, China has developed flexibility in precision Dongguan precision casting skills, continuous Dongguan precision casting skills, special Dongguan precision casting skills, Dongguan precision casting automation, and Dongguan precision casting component imitation skills. The main technological processes of Dongguan precision casting include: metal smelting, model manufacturing, pouring coagulation and demolding finishing. The primary materials used in Dongguan precision casting are cast steel, cast iron, and Dongguan precision casting non-ferrous alloys (copper, aluminum, zinc, lead, etc.).
Dongguan precision casting process can be divided into:

1. Gravity Dongguan Precision Casting,

2. Pressure Dongguan Precision Casting

3. Dongguan precision casting of sand mold.
The Dongguan precision casting method is usually sand mold Dongguan precision casting, followed by special Dongguan precision casting methods, such as metal precision casting, investment Dongguan precision casting, plaster Dongguan precision casting, etc. The sand mold Dongguan precision casting can be divided into clay sand mold Dongguan precision casting, organic binder sand mold Dongguan precision casting, resin self-hardening sand mold Dongguan precision casting, lost foam Dongguan precision casting and so on.
Dongguan precision casting refers to the process of injecting molten metal into the mold under the effect of the earth's gravity, also called casting.

Precision casting includes sand casting, metal casting, investment Dongguan precision casting, mud mold Dongguan precision casting, etc. The narrow definition of gravity Dongguan precision casting refers to metal casting. Pressure Dongguan precision casting is a process of injecting molten metal into the mold under the action of other external forces (not including gravity). The broad sense of pressure Dongguan precision casting includes the pressure of the die casting machine, low pressure Dongguan precision casting, and centrifugal Dongguan precision casting, etc.; the narrow meaning of pressure Dongguan precision casting refers to the metal mold pressure of the die casting machine, referred to as die casting. These kinds of Dongguan precision casting processes are the most commonly used in non-ferrous metal precision casting in Dongguan, and they are also the cheapest. Dongguan precision casting is a traditional Dongguan precision casting process that uses sand as the primary modeling material to make molds.
