¿Qué herramientas son cruciales para la fabricación de chapa?
The following are the basic tools and techniques of sheet metal processing, combining the guidance of the sheet metal gauge Gráfico:
1. herramientas de corte
- Laser Cutting Machine: Suitable for thin plates (≤6mm) with accuracy ±0.02mm. See thickness chart for power and focus selection.
- CNC punch: For medium thickness plates (1-8mm), the thickness map parameters (e.g. punch spacing, plate thickness ratio, etc.) are matched through the mold library.
- Plasma/waterjet cutting: applies to thick plates (>8mm), adjusting cutting speed and air pressure through thickness chart to reduce thermal deformation.
2.Bend tools
- Bend machine: Adjust the opening angle of the V-shaped groove according to the sheet metal gauge chart (e.g. 1.5mm aluminum plate requires an opening angle of 88° for V-shaped groove).
- The gap between the lower molds should be set according to the formula (gap= thickness * coefficient) to prevent the galvanizing layer from peeling or aluminum from cracking.
- Roll bending machine: For cylindrical/curved parts, choose roller spacing and feed speed according to thickness diagram.
3.Forming mold
- Stretch molds: For deep presses (such as car coverings), mold fillet radius (≥1.5T is selected based on thickness diagram).
- Round rolling die: When rolling a sheet (≤2mm), pre-lubricating oil is needed to reduce friction coefficient.
Metal plate connection tools and techniques
MIG/TIG welding machine:
- Thin plates (≤3mm) are welded with pulses to avoid burnout (current range 50-150A).
- The thickness plate (>3mm) is welded in several layers and the temperature and weld spacing between the layers are determined in accordance with the thickness diagram.
Laser welding: Precision components,such as electronic components, require adjustment of spot diameter and focus.
2.Riveting tools
- Rivet gun: Select rivet diameter to match plate thickness.
- Hydraulic riveters: Calibration pressure values (≥8 tons for 3mm plates) are required for heavy duty plates (e.g. stainless steel).
3.Adhesive technology
- Epoxy resin adhesives: For sheet adhesives (such as electronic device casings), the thickness of the adhesive layer (0.1-0.3mm) should be controlled.
- Structural adhesive: When splicing thick plate, it must be combined with the curing schedule.

How do global and local factors affect sheet metal fabrication?
1.Global drivers
- Technological innovation: Automation (robotic bending), promotion of new materials (aluminium/titanium alloy), improvement of accuracy and efficiency.
- Economic volatility: Raw material prices and tariff policies,such as the U.S.-China trade friction that has caused North American sheet metal companies to turn to local or Southeast Asian suppliers, have forced supply chain localization to localize.
- Environmental pressure: Global carbon reduction targets promote green manufacturing, such as requiring sheet metal companies in the Los Angeles area to adopt solar powered equipment and waste recycling systems. The rental for sale model, which requires manufacturers to design detachable and recyclable sheet metal components, is being promoted in the European market.
2.Key local elements
- Cost and skills: Developed countries tend to automate (Los Angeles has higher labor costs), while developing countries,such as Southeast Asia, rely on low-cost labor.
- Industry clusters: Los Angeles's automotive and aviation industry clusters driving sheet metal manufacturing toward precision and customization, such as rapid mass production of Tesla panels.
- Policy and logistics: California's strict air pollution control regulations restrict traditional welding processes and promote laser welding. As a major global hub, Port of Los Angeles has shortened the import and export cycles for raw materials and products, but also faces the risk of delivery delays caused by port congestion.
3.Industry Future Trends
