Automotive stamping parts have the following characteristics:

1. Process related characteristics

      High production efficiency: Automotive stamping parts are produced using stamping technology, relying on equipment and molds such as punching machines, which can complete the processing of a large number of parts in a short period of time. For example, in the production of automotive coverings, a large-scale stamping production line can complete the stamping of multiple parts per minute, which greatly improves production efficiency compared to other processing methods and meets the needs of large-scale automotive production.

     High precision: The precision of stamping molds is usually high, which can ensure the dimensional accuracy and shape accuracy of stamping parts. Generally speaking, the dimensional tolerance of stamped parts can be controlled within a small range, such as ± 0.05mm to ± 0.5mm. For some key automotive stamped parts, such as engine mounts, high precision can ensure their good assembly with other components, ensuring the overall performance and quality of the car.

     Good consistency: Under the same stamping process and mold conditions, the stamped parts produced have a high degree of consistency. Both the appearance shape and size specifications can be kept basically the same, which is beneficial for quality control and assembly operations in the automotive production process, reducing assembly problems and quality hazards caused by differences in parts, and improving the reliability and stability of automotive products.

2. Performance related characteristics 

     Good strength and stiffness: Automotive stamping parts are usually made of high-strength steel plates and other materials, which can achieve good strength and stiffness after stamping and forming. For example, the body structural components of a car, such as A-pillars and B-pillars, can be formed with reasonable stress distribution in specific directions through stamping technology, improving their collision resistance and ensuring the safety of passengers inside the car.

     Lightweight advantage: With the development trend of automotive lightweighting, stamping parts can achieve lightweight design while ensuring performance. By adopting advanced stamping technology and high-strength, low-density materials such as aluminum alloy and high-strength steel, the weight of the car can be effectively reduced, fuel consumption and exhaust emissions can be reduced, and the fuel economy and environmental performance of the car can be improved without reducing the strength and stiffness of the parts.

     Strong corrosion resistance: Some automotive stamping parts will undergo surface treatment, such as galvanizing, painting, etc., to improve their corrosion resistance. For example, the stamping parts of the car chassis, after galvanizing treatment, can effectively prevent rusting and corrosion in harsh environments such as humidity and mud, extend the service life of accessories, and ensure the stability and safety of the car chassis.

3. Characteristics related to cost and design

     High material utilization rate: Stamping technology can fully utilize sheet materials and reduce waste generation through reasonable layout design. Generally speaking, the material utilization rate of stamped parts can reach about 70% to 90%. Compared with other processing methods such as cutting, it can effectively reduce material costs and improve economic benefits.

     High design flexibility: Stamping technology can achieve the production of various complex shapes and structures of parts. Designers can flexibly design the shape, size, and structure of stamping parts according to the overall design requirements of the car. For example, car fenders, doors, and other coverings can achieve smooth lines and unique shapes through stamping technology, meeting the exterior design requirements of cars and enhancing their aesthetics and market competitiveness.

     Low overall cost: Although the initial investment in stamping molds is relatively large, in the case of large-scale production, the cost of a single stamping component will decrease with increasing output. Moreover, the stamping process has high production efficiency and material utilization, with relatively few subsequent processing steps. Overall, this makes automotive stamping parts have a lower cost advantage in large-scale production, which is conducive to reducing the overall production cost of automobiles.
