Splitting and Layout: Complex, monolithic shapes are broken down into several machinable components, and the sheet metal layout is performed simultaneously to optimize material utilization and minimize waste.
2. Substrate Processing and Forming: Shaping the Basic Form
Sheet Cutting: A CNC cutting machine is used to precisely cut the aluminum alloy sheet metal according to the split dimensions, ensuring a dimensional error within ±0.5mm, laying the foundation for subsequent forming.
Bending and Forming: For regular curved or angled shapes, a CNC press brake is used. Multiple, step-by-step bending allows for precise control of the bending angle to prevent cracking caused by excessive force applied simultaneously.
For complex curved or wavy shapes, a CNC stretch bending machine or hydraulic forming machine is used. The sheet metal is stretched or pressed into the desired curve using a mold, ensuring a smooth and natural curve.
Welding and Splicing: For complex shapes that cannot be formed in one piece, multiple components are joined together using argon arc welding. The weld seams are then polished and polished to ensure a smooth surface with no visible weld marks. 3. Sanding and Repair: Optimizing Surface Texture
Rough Sanding: Initial sanding is performed to remove weld marks, burrs, and bend marks, ensuring a generally smooth surface.
Fine Sanding: Fine sanding is performed using fine sandpaper or a grinder to improve surface smoothness and ensure even adhesion of subsequent coatings.
Defect Repair: Minor dents, scratches, and other defects that occur during the molding process should be repaired using filler putty and additional sanding to ensure a flawless finished surface.
4. Surface Treatment: Improving Decorative and Weather Resistance
Pre-treatment: Degreasing, rust removal, and chroming are performed on the molded panels to remove surface oil and impurities and enhance coating adhesion.
Coating: Fluorocarbon spraying, powder coating, or wood grain transfer printing can be selected based on design requirements. Fluorocarbon spraying is preferred for outdoor applications to ensure weather resistance. Powder coating or transfer printing can be used to create a variety of colors and textures depending on the style of the interior. Finished Product Inspection: Surface coating uniformity, color variation, and adhesion are tested, while also verifying the conformity of the design dimensions with the design model to ensure the finished product is qualified.
