Automotive precision die-casting parts

Automotive precision die-casting parts usually refer to automotive components manufactured by the die-casting process with high precision requirements. These parts generally have complex shapes and strict dimensional tolerance requirements.

Die-casting is an efficient metal forming process that can produce thin-walled, complex-shaped parts with high dimensional accuracy. Common materials for automotive precision die-casting parts mainly include aluminum alloys, zinc alloys, etc.

Aluminum alloys have been widely used under the trend of automotive lightweighting due to their advantages such as low density, high strength, and good corrosion resistance. It can be used to manufacture various structural parts, shell parts, engine components of automobiles, such as the shells of batteries, motors and electronic control systems, as well as aluminum alloy die-castings of fuel vehicle power and transmission systems, automotive lightweight structural parts (body and chassis), interior parts (seat frames, center consoles, instrument panels), etc. For example, the main products of Dalian Yaming Automotive Components Co., Ltd. cover aluminum alloy die-castings of new energy vehicle three-electric systems, fuel vehicle power and transmission systems, etc. The company's customers include global top vehicle or component enterprises such as Toyota, Mercedes-Benz, Volkswagen, and Ford.

Zinc alloy die-casting parts have good die-casting performance, high dimensional accuracy and surface quality, and are often used in some automotive parts with high requirements for appearance and accuracy, such as bases of automotive spare parts and automotive door lock parts.

When choosing automotive precision die-casting parts, the following factors need to be considered:

Application location: Choose the appropriate die-casting parts according to the specific automotive location and functional requirements.

Material characteristics: Such as the lightweight and corrosion resistance of aluminum alloys, the die-casting performance and surface quality of zinc alloys, etc.

Dimensional accuracy: Ensure that the dimensions of the parts meet the design requirements to ensure the assembly accuracy with other components.

Mechanical properties: Including strength, hardness, toughness, etc., to meet the usage requirements of the vehicle under various working conditions.

Surface treatment: Conduct corresponding surface treatments as needed, such as electroplating, polishing, anodic oxidation, etc., to improve the corrosion resistance and appearance quality of the parts.

Supplier qualifications: Choose suppliers with good reputation and production capacity to ensure product quality and delivery cycle.
