Product Details
I. Principles of Sheet Metal Manufacturing
Sheet metal manufacturing is a technology that involves shaping parts by processing thin metal sheets (typically 0.5-6mm thick) through processes such as cutting, stamping, bending, welding, and surface treatment. Its core characteristics are lightweight design, high precision, low cost, and ease of mass production, making it widely used in industries such as automotive, electronics, home appliances, aerospace, and medical devices.
II. Core Process Flow of Jiesen Sheet Metal Manufacturing
| 1. Design and Engineering | CAD Design: Creating 3D models of sheet metal parts using computer-aided design (CAD) software. Unfolding: Unfolding the 3D model into a 2D flat pattern for cutting and forming. |
|||||||||||
| 2. Material Selection | Commonly used materials include stainless steel, aluminum, copper, cold-rolled steel, and galvanized steel. The choice of material depends on the product's application scenario, strength requirements, and corrosion resistance. |

3. Cutting |
Common techniques/purposes |
Cutting the metal sheet into blanks of the required shape. | ||||||||||
| Laser Cutting | Uses a high-energy laser beam to melt the material, offering high precision (±0.1mm) and suitability for complex contours (such as intricate patterns). | |||||||||||
| CNC Punching Machine | Uses die cutting, offering high efficiency and suitability for mass production of standard shapes (such as square holes and round holes). | |||||||||||

| 4. Forming | Key technologies/objectives |
Transforming flat sheet metal into a three-dimensional shape through plastic deformation. | ||||||||||
| Bending | Using a bending machine and dies, pressure is applied to the sheet metal to form V-shaped, U-shaped, and other angles. Process key points: Bending coefficients (K-factor) and springback compensation must be calculated to ensure angle accuracy. |
|||||||||||
| Stamping | Uses dies to perform processes such as punching, stretching, and flanging, suitable for precise features (e.g., bosses, louvers). Progressive dies/compound dies: Efficient production of complex parts (e.g., connector terminals). |
|||||||||||
| Roll Forming | A process that gradually bends long, strip-shaped parts (such as guide rails and metal tubes) using multiple sets of rollers. | |||||||||||
| Spinning | Used for forming curved surfaces of axially symmetrical parts (such as lampshades and conical parts). | |||||||||||
| 5. Joining | Welding/Purpose |
To assemble multiple sheet metal parts into a complete structure. | ||||||||||
| TIG/MIG welding | Suitable for precision welding of materials such as stainless steel and aluminum. | |||||||||||
| Spot welding | Efficiently connects thin sheets (such as car body panels). | |||||||||||
| Riveting | Uses rivets or self-tapping screws to avoid thermal deformation (e.g., aircraft skin). | |||||||||||
| Bonding | Structural adhesive bonding, suitable for applications requiring high lightweighting (such as electronic product casings). | |||||||||||
6. Surface Treatment |
Common Processes/Purposes | To improve corrosion resistance, aesthetics, or functionality. | ||||||||||
| Coating | Electrostatic powder coating (appliance casings), baked enamel (automotive parts). | |||||||||||
| Electroplating | Zinc plating (corrosion resistance), nickel plating (wear resistance), chromium plating (decorative). | |||||||||||
| Anodizing | A protective oxide film is formed on the surface of aluminum (e.g., in mobile phone frames). | |||||||||||
| Brushing/Polishing | Improves surface texture (e.g., stainless steel signs). | |||||||||||
| 7. Quality Control | Dimensional Inspection | Dimensional accuracy is checked using tools such as calipers, micrometers, and coordinate measuring machines. | ||||||||||
