Production process

Process

Cutting

According to the size of the drawing with a shearing machine or laser cutting machine to cut aluminum plate, special shape or ventilation holes, using CNC punch or engraving machine processing.

Forming process

The aluminum sheet is folded into the design shape (such as arc, right Angle, etc.) by CNC bending machine.

Arc rolling: The arc rolling machine into a cylindrical or curved shape.

Welding and strengthening

Group welding: Complex structures need to be welded and spliced, and argon arc welding is used to ensure strength.

Reinforcement reinforcement: back welded reinforcement (corner code or keel) to improve deformation resistance.

Surface treatment

Cleaning: alkali washing to remove oil, pickling (chromified/chromium-free passivation) to enhance adhesion.

Drying: Ensure that the surface is dry and free of impurities.

Coating process

Spraying: electrostatic spraying primer → fluorocarbon top paint → varnish (strong weather resistance).

Anodizing: electrolysis to form an oxide film to improve wear resistance.

High temperature curing: After spraying, enter the baking oven (180~250℃) to cure the coating.

Quality inspection

Size inspection: Check whether the length, width and bending Angle conform to the drawing.

Coating test: film thickness (≥30μm), color difference, adhesion (grid test), corrosion resistance (salt spray test).

Strength test: Check the stability of welding points and stiffeners.

Packing and Transportation

Protection treatment: Stick protective film to prevent scratching, and install corner protection on the edge.

Packing: fixed in wooden cases or pallets according to specifications, marked with moisture-proof and anti-collision marks.
