Profile Cutting and Frame Assembly Aluminum alloy door processing begins with the precise cutting of profiles. After the aluminum profiles are cut to the design dimensions using CNC equipment, the frame is assembled using corner bracket connections or welding processes.
Key points:
Cutting precision: Error must be controlled within 0.5mm
Corner assembly method: 45° bevel splicing requires the use of special corner adhesive
Strength test: Finished products must pass a 2000-cycle opening and closing durability test
Surface treatment process selection Different scenarios require different surface treatments:
Anodizing: Forms a 10-25μm oxide film, suitable for humid environments
Powder coating: Thickness 60-120μm, offering 20+ color options
Wood grain transfer: Imitates real wood grain; special coating is required in areas with large temperature differences
Hardware system integration solution Hardware components directly affect service life:
Hinge load-bearing capacity: Single-leaf doors require hinges with a load-bearing capacity of ≥80kg
Lock body installation: Pre-drilled hole position error must be <1mm
Sealing strip configuration: EPDM rubber strips have better weather resistance than PVC
