Cutting: The First Step to Precise Material Preparation
The first step in stainless steel processing is like a tailor taking measurements-using a laser cutter or waterjet cutter, the product outline is cut into a 3mm thick sheet with a precision of 0.1mm. This process is akin to surgery, requiring a smooth, burr-free cut while avoiding heat-affected zones that could deform the material. Interestingly, modern cutting equipment can process 10 layers of sheet metal simultaneously, making it 20 times more efficient than traditional shearing machines.
Shaping: Transforming Steel Sheets into Three-Dimensional Works of Art
The cut sheet metal then undergoes "shaping surgery": a hydraulic press with 2000 tons of pressure presses the flat steel sheet into complex curved surfaces within 5 seconds. This process is like sculpting clay, but stainless steel has a much lower springback rate, requiring precise calculations of compensation. Even more remarkably, some products require 3-5 progressive shaping processes, with each deformation controlled within 15% to ensure a final dimensional accuracy of ±0.2mm.
Welding and Surface Treatment: A Transformation from Rough to Refined The finished workpiece undergoes a "cosmetic surgery": first, argon arc welding is used to weld the various components into a whole, with the weld width controlled within 3 millimeters to avoid affecting the aesthetics. Then comes the surface treatment stage-first, welding marks are removed by grinding with 800-grit sandpaper, then electrolytic polishing technology is used to achieve a mirror-like finish, and finally, passivation treatment is performed to enhance corrosion resistance. The entire process is like giving stainless steel a spa treatment; the final product can withstand 1000 hours of salt spray testing without rusting.
