Classification of Manufacturing Automotive Castings
Automotive castings refer to components processed through casting processes in automotive components. According to different casting processes, automotive castings can be divided into the following categories:
1. Sand casting parts
Sand casting is a common casting process that involves pouring casting materials into the sand mold, allowing the material to solidify, and then breaking the sand mold to remove the casting. This process produces a wide variety of automotive castings, including engine cylinder heads, crankcases, crankshafts, gears, etc.
2. Precision casting parts
Precision casting is a high-precision and high-quality casting process suitable for manufacturing high-precision and high-strength components in automotive components. The types of automotive castings manufactured by this process are limited, but the quality is extremely high, including wheels, brake discs, steering gears, etc.
3. Low pressure casting parts
Low pressure casting is a process of applying low pressure to fill a mold with casting material, and after the casting material solidifies, the mold is separated and the casting is taken out. There are not many types of automotive castings manufactured by this process, but the manufacturing efficiency is high and the quality is stable, including automotive chassis components, steering gears, hydraulic pump bodies, etc.
Automotive castings are an indispensable part of automotive components, widely used in automotive engines, transmissions, chassis, steering, braking, and other aspects. Among them, sand casting parts are widely used and have low manufacturing costs, making them suitable for mass production; High manufacturing cost of precision castings, suitable for vehicle models or high-precision components; Low pressure casting parts have high production efficiency and are suitable for mass production of components that require stable quality.
In short, automotive castings play an important role in automotive manufacturing, and the automotive castings produced by different casting processes have their own advantages in application, meeting the diverse needs of automotive manufacturing.
