Common Stamped Metal Sheet Materials

1. Carbon Steel Sheets (Best Cost-Effectiveness)

Cold-rolled steel sheet (SPCC): Smooth and flat surface, good toughness, suitable for stretching and bending; mainstream material for home appliance housings and chassis housings.

Hot-rolled steel sheet (SPHC): Thicker, with an oxide scale on the surface; mostly used for structural supports and thick-part stamping.

Galvanized steel sheet (SGCC): Galvanized surface for rust prevention; used for air conditioner housings, distribution boxes, and outdoor hardware.

2. Stainless Steel Sheets Rust-proof and Corrosion-resistant

304, 201, and 316 stainless steel sheets, acid and alkali resistant, rust-free, used in kitchenware, equipment housings, medical devices, and decorative stamping parts.

316 is suitable for seawater and chemically corrosive environments.

3. Aluminum Alloy Sheets (Lightweight)

1-series pure aluminum, 3-series rust-resistant aluminum, and 5-series aluminum-magnesium alloy sheets, lightweight and easy to stamp, used in new energy vehicle housings, automotive body panels, and electronic product housings.

4. Other Metal Sheets

Copper Sheets (Brass, Copper): Conductive stamping parts and terminals;

Tin-plated Sheets: Food packaging and precision electronic components.

Core Process Classification of Stamped Metal Sheets

Separation Process (Sheet Cutting and Splitting)

Punching, blanking, edge trimming, cutting, and grooving remove excess material from the sheet, separating the part outlines.

Forming Process (Plastic Deformation of Sheet Metal, Without Cutting)

Bending: Bending flat sheets into L-shaped and U-shaped supports;

Stretching Deep Drawing: Pressing flat sheets into bowl shapes, shells, and deep boxes (water cups, car fuel tank shells);

Ribing Embossing: Increasing the rigidity of sheet metal and preventing deformation of thin sheets;

Flanging: Flanging the edges of holes for screw assembly;

Embossing Relief: Surface texture decoration stamping.

Advantages of Stamping Process

High Efficiency and Low Cost: Stamping processes are fast (high-speed presses can reach hundreds or even thousands of times per minute), easily mechanized and automated, and have low unit production costs.

High Precision and Consistency: Precision molds ensure the dimensional accuracy (down to the micron level) and shape consistency of stamped parts, providing identical interchangeability.

High Strength and Lightweight: Stamped parts are thin, uniform, light, and strong. The cold work hardening effect gives stamped parts high strength and rigidity, and allows for the manufacture of complex structures with reinforcing ribs.

Wide material adaptability: It can process parts with a wide range of sizes and complex shapes, from small watch hands to large automotive longitudinal beams and body panels.

Today, sheet metal stamping technology has deeply penetrated multiple industries. Automotive body panels and chassis components, home appliance equipment housings and internal supports, electronic and electrical chassis and heat dissipation components, as well as new energy storage housings and medical device hardware accessories, all commonly utilize stamping processes. Combined with subsequent surface treatments such as painting, galvanizing, wire drawing, and anodizing, stamped metal parts can meet structural requirements as well as diverse functional requirements such as corrosion resistance, aesthetics, and conductivity.

Overall, sheet metal stamping is a mature process that balances efficiency, precision, and practicality. While lacking complex processing steps, it supports most of the sheet metal manufacturing needs of modern light and heavy industries. With its stable and reliable performance, it has become a long-standing core process in industrial manufacturing, continuously empowering production across various industries.
