Process flow:
1. Material selection:
Metal legs are usually made of materials such as stainless steel, aluminum alloy, iron alloy or cold-rolled steel. These metals have high strength, corrosion resistance and plasticity, and are suitable for making furniture legs.
2. Cutting and shaping:
Using techniques such as laser cutting, CNC stamping or precision die stamping, the metal sheet is precisely cut into the required shape and size to ensure a precise fit for each part of the leg.
3. Welding or assembly:
For metal legs with complex structures, it may be necessary to weld the various components together through argon arc welding, resistance welding or laser welding to ensure that the structure is strong and there are no obvious weld marks. For modularly designed metal legs, they are assembled through bolts, rivets or nested connections for easy disassembly, transportation and installation.
4. Surface treatment:
After welding or assembly is completed, the metal surface is ground and polished to remove burrs, welding slag and rough surfaces to improve the tactile and visual effects.
Then carry out surface protection treatment, such as electroplating (such as chromium plating, nickel plating, zinc plating, etc.), spraying (powder spraying or liquid spraying), anodizing, baking paint, wire drawing, polishing, etc., to enhance the anti-corrosion ability of the metal and at the same time give it Various colors and textures, such as glossy, matte, frosted, antique and other effects.
5. Quality inspection:
After completing all processes, the metal legs undergo strict quality inspections, including structural stability testing, load-bearing testing, surface coating adhesion testing, etc., to ensure the safety and durability of the product.
