Raw Material Inspection: Chemical composition analysis and mechanical property testing are performed on raw materials such as aluminum alloy castings to ensure they meet relevant standards and design requirements. Chemical composition analysis generally employs methods such as spectral analysis, while mechanical property testing includes tensile testing and hardness testing.
Finished Product Inspection: Finished aluminum profiles for curtain walls undergo visual inspection, dimensional measurement, and surface treatment quality inspection. Visual inspection primarily checks for defects such as scratches, cracks, and deformation on the profile surface; dimensional measurement ensures the profile's dimensional accuracy meets design requirements; surface treatment quality inspection includes testing indicators such as oxide film thickness, coating thickness, and adhesion.
Furthermore, the mechanical properties, thermal insulation performance, and airtightness of the profiles also need to be tested to ensure the overall performance of the curtain wall meets requirements.
