Precision castings are an indispensable and important component in modern manufacturing industry. Their manufacturing process requires support from precision casting equipment and process flow, as well as high-quality technical personnel for operation. Only under strict quality control can precision castings meet the needs of users and make greater contributions to the development of society.

Precision castings are an important form of casting technology, with stricter manufacturing process requirements. However, due to the high cost of mold manufacturing required, it is necessary to first design and plan the entire casting process and mold manufacturing in the production process to ensure that there are no deformation, defects, and other problems during the manufacturing process. For precision castings, it is necessary to ensure that their dimensional accuracy, surface smoothness, and performance indicators can meet the requirements of use.

What are the common materials in precision castings?

Alloy steel: Alloy steel is a material with high strength, high hardness, and wear resistance. It is widely used in the manufacturing of bearing seats, transmission wheels, cutting tools, and other precision castings.

Stainless steel: Stainless steel has corrosion resistance, high temperature resistance, and good machinability. It is commonly used in precision casting to manufacture pipeline connectors, valves, pump bodies, etc.

Aluminum alloy: Aluminum alloy has the characteristics of good thermal conductivity, lightweight, and easy processing. It is widely used in fields such as aerospace, automotive manufacturing, and electronic equipment.

Copper alloy: Copper alloy has good conductivity and thermal conductivity, as well as good mechanical properties. It is commonly used in the manufacturing of electrical components, ship components, automotive transmission components, etc.

Titanium alloy: Titanium alloy has low density, high strength, and good corrosion resistance. It is widely used in fields such as aerospace, chemical industry, medical equipment, etc.

Nickel alloy: Nickel alloy has the characteristics of high temperature resistance, corrosion resistance, and good thermal fatigue performance. It is widely used in fields such as aviation engines, nuclear industry, and chemical equipment.

Steel: Steel is a common metal material with excellent mechanical properties and processability. It is often used to manufacture mechanical parts, building structures, and other precision castings.

The manufacturing process of precision castings requires strict process flow. During the casting process, it is necessary to control parameters such as the temperature of the casting, the filling speed of the mold, and the cooling speed of the casting. These parameters directly affect the dimensional accuracy and physical properties of castings. Therefore, when formulating the process flow, it is necessary to conduct scientific design based on specific product requirements, and at the same time, experienced craftsmen are required to carry out practical operations.

In the process of sand mold preparation, precision castings are usually made of high-temperature and high hardness refractory materials to ensure the accuracy and surface smoothness of the castings. Sand molds can be prepared through two methods: manual molding and mechanical molding. Handmade shaping is a traditional preparation method with a simple process but a long preparation cycle; Mechanical modeling is a new type of preparation method developed in recent years, which has the advantages of fast preparation speed and low cost.
