Precision castings have the characteristics of precise size, smooth surface, and complex shape, which can replace traditional processing methods, reduce production costs and processing difficulties. In the aerospace field, precision castings can manufacture complex aerodynamic components and structural parts, improving the performance and safety of aircraft. In the automotive industry, precision castings can produce high-strength and lightweight components, improving the fuel economy and handling performance of automobiles.

High precision castings: capable of producing castings with dimensional accuracy of ± 0.1mm or even higher, meeting the needs of various high-precision equipment. Low surface roughness can reduce subsequent processing steps and improve production efficiency. Complex shape: It can produce castings with complex inner cavities, thin walls, and irregular structures to meet the diverse needs of product design.

What are the precautions for selecting materials for precision castings?

Select appropriate materials according to product requirements. When selecting the material for precision castings, it is necessary to first determine the performance indicators such as hardness, strength, and toughness of the material according to the product's usage requirements, and then choose the appropriate material.

Pay attention to the corrosion resistance of the material. Some precision castings may be used in harsh environments, so when selecting materials, their corrosion resistance should be considered to ensure long-term stable operation of the product in harsh environments.

Pay attention to the processing performance of the material. The processing performance of different materials varies, some are easy to process, while others are difficult to process. When selecting materials, one should consider the production and manufacturing process of the product and choose materials with good processing performance.

Pay attention to the cost of materials. The selection of materials also needs to consider cost factors, choosing economical and practical materials to ensure product performance and quality while reducing production costs.

Pay attention to the reliability of the material. When selecting materials, their reliability should also be considered. Choose materials with stable performance and reliability to ensure the long-term reliable operation of the product.

Pay attention to material resources and environmental issues. In material selection, attention should be paid to the resource sustainability and environmental friendliness of the material, and materials that meet environmental requirements should be selected to reduce the impact on the environment during the production process.

The manufacturing process of precision castings includes multiple stages such as mold design, material selection, melting and casting, sand removal and cleaning, and heat treatment. Among them, mold design is a key link in precision casting, which directly affects the dimensional accuracy and surface quality of castings. Material selection is also crucial, usually choosing high-quality alloy materials to ensure the mechanical properties and corrosion resistance of castings.

Accurate mold design and high-quality mold manufacturing are key to ensuring the accuracy and quality of precision castings. The dimensional accuracy, surface smoothness, and cavity structure of the mold directly affect the quality of the casting. Strictly control the chemical composition and impurity content of metal materials, as well as the quality of refractory materials, to ensure that raw materials meet the requirements of precision casting.
