Metal accessories formed by stamping process are made of metal sheets such as carbon steel, stainless steel, and aluminum alloy. They are formed in one piece through stamping processes such as blanking, punching, bending, and stretching, relying on high-precision molds and presses. From precision brackets for electronic equipment to structural connectors for automobiles, to protective components for mechanical equipment, they cover a wide range of industries such as electronics, automobiles, machinery, and home appliances. With the efficiency and precision of the stamping process, metal sheets are transformed into functional components of various shapes and precise sizes, providing basic guarantees such as structural support, functional connection, and protective adaptation for equipment in various industries. They are core components that combine standardization and customization in modern industrial production.
II. Product Features
(I) Core Advantages
1. High precision and consistency: The mold accuracy is controlled at ±0.05mm, the dimensional tolerance of stamping parts is extremely small, and the consistency is high during mass production. It is suitable for automated assembly lines, such as connector accessories for electronic equipment, to ensure stable operation of the equipment.
2. High strength and lightweight: The metal sheet is hardened by stamping cold work, and the strength is increased by 10% - 30%. At the same time, lightweight is achieved by optimizing the structure (such as hollowing and thin-wall design), balancing equipment performance and weight reduction requirements, such as car seat frame accessories, taking into account both load-bearing and energy saving.
3. High efficiency and low cost: The stamping process is continuous and efficient, and a single device can complete dozens of forming times per minute. Compared with cutting and casting processes, the production cycle is shortened by more than 50%, greatly reducing unit costs, and is suitable for large-scale mass production.

III. Product Details
(I) Process Flow
1. Mold Design: Based on product requirements, the mold is designed using CAD/CAM technology, including punch, die, and unloading device. After CNC machining, EDM forming, and heat treatment (hardness reaches HRC58-62), the mold accuracy and life (≥500,000 stampings) are ensured.
2. Raw material pretreatment: The metal sheet is flattened, leveled, degreased and rusted to ensure the flatness (≤0.1mm) and cleanliness of the sheet, laying the foundation for precise stamping.
3. Stamping: On a 100-1000T press, the blanking, punching, bending and other processes are completed according to the mold. The servo system accurately controls the pressure and stroke to achieve one-time forming of complex shapes, such as the arc surface of the stretched part and the sharp angle of the bent part.
4. Post-processing: deburring, grinding, optional surface treatment (galvanizing, anodizing, painting), enhanced anti-corrosion and wear resistance, adapted to different working conditions, such as galvanizing of outdoor equipment accessories, salt spray test up to 480 hours.
(II) Applicable materials and scenarios
Carbon steel (Q235/Q345): high strength, low cost, suitable for automotive chassis brackets, mechanical equipment housings and other scenes with high strength requirements.
Stainless steel (304/316): corrosion-resistant, easy to clean, used for food machinery, medical equipment accessories, such as medical equipment connection components.
Aluminum alloy (6061/5052): light weight, good thermal conductivity, suitable for electronic equipment heat sinks, aerospace lightweight components.
(III) Quality Control
Build a "three-level quality inspection" system: first-piece inspection (full-size inspection + mechanical properties sampling), process inspection (monitoring mold wear and product size every 2 hours), and finished product final inspection (three-coordinate measuring machine + visual inspection system, 100% screening of size and appearance defects). Verify performance through tensile testing and salt spray testing to ensure that products comply with standards such as GB/T 13914, providing a reliable "metal foundation" for equipment in various industries.
