The production process comprises three main stages: melting and casting, extrusion, and surface treatment.
Melting and Casting: Aluminum ingots are melted with elements such as magnesium and silicon in a specific ratio to form alloy grade billets such as 6063-T5.
Extrusion: Forming is performed using a 3500-ton extruder, with high-precision products having dimensional tolerances controlled within ±0.08mm.
Surface Treatment: Oxide film thickness ≥10μm, powder coating thickness 40-120μm, and wood grain transfer requires passing a 2000-hour neutral salt spray test.
Key technical indicators include:
Wind Pressure Resistance: No structural deformation under level 9 wind pressure (≥5.0kPa).
Repeated Opening and Closing Durability: Window products pass 30,000 opening and closing cycles.
Thermal Insulation Coefficient: The thermal conductivity of the thermally broken profile is ≤2.5W/(m²·K).
