What is sheet metal fabrication? | Sheet metal processing technology is a comprehensive cold processing technique for thin metal sheets (with a thickness usually not exceeding 6 millimeters). Its core feature is to maintain uniform thickness of the parts throughout the processing. This process transforms flat metal sheets into the desired three-dimensional shapes and structures through a series of procedures. It is widely applied in fields such as car exteriors, computer cases and cabinets, ventilation ducts, architectural decorations, and mechanical equipment exteriors. |
Commonly Used Materials in sheet metal fabrication products | 1. Common Cold-rolled Sheet SPCC 2. Galvanized Sheet SECC 3. Hot-dip Galvanized Sheet SGCC 4. Stainless Steel SUS301 5. Stainless Steel SUS304 |
Advantages of precise stamping products | Lightweight: Utilizing thin metal plates, the overall structure is lightweight. High strength: Through cold processing techniques, the material strength is maintained or enhanced. Good conductivity: The metal material endows it with excellent conductivity, suitable for electronic applications. Low cost: Suitable for large-scale production, with high material utilization rate and relatively low overall manufacturing cost. Good mass production performance: High degree of process standardization, easy to achieve automation and mass production. |
Key Steps of Sheet Metal Fabrication Process | Cutting and Trimming: The modern techniques often employ numerical control technology, such as laser cutting , plasma cutting , and water jet cutting. Forming processing: The main process is bending, where a CNC bending machine is used to precisely control the angle. Connection and Assembly: The most commonly used connection method is welding, including arc welding, laser welding, resistance spot welding, etc. Surface treatment: Common methods include spraying, electroplating , anodizing, as well as polishing, sandblasting, etc. |
Accuracy of sheet metal fabrication parts | Laser cutting: The precision is usually around ±0.1 mm, which is the foundation for ensuring the accuracy of subsequent processing. Bending: The tolerance is generally in the range of ±0.2 mm to ±0.5 mm, depending on the material's springback and process control. Welding: The tolerance range is relatively wide, typically ranging from ±0.3 mm to ±0.5 mm |
General material thickness range for sheet metal fabrication products | Thin plate : 0.5mm - 1.5mm (most commonly used, such as automotive sheet metal, electronic chassis) Medium plate: 1.5mm - 6mm (balances strength and machinability) Thick plate: Above 6mm (requires specialized equipment, used for heavy structures) |
