After the solar frame aluminum profile is produced, it needs acceptance inspection, and the inspection can only enter the next process after passing the inspection. Today we will learn the methods and standards of solar frame aluminum profile inspection.
1. Flatness: Place the aluminum profile working surface on the full-length testing platform (length greater than 3200mm), use a 0.15mm feeler gauge, and insert it between the aluminum profile working surface and the testing platform from both sides of the aluminum profile, section by section. Detection (detection length is less than 100mm). If the feeler gauge cannot be inserted, it is not qualified.
2. Straightness: Place the four edges and corners of the aluminum profile obliquely on the full-length inspection platform (length greater than 3200mm), use a 0.5mm feeler gauge, and insert it between the edges and corners of the aluminum profile and the inspection platform from one side of the aluminum profile, section by section (detection length is less than 100mm). If the feeler gauge cannot be inserted, it is not qualified.
3. Distortion: place the two aluminum profiles side by side on the full-length inspection platform (length greater than 3200mm), use a 0.5mm feeler gauge, insert them from the middle of the two aluminum profiles, and test section by section (the detection length is less than 100mm). If the feeler gauge cannot be inserted, it is not qualified
4. Appearance dimensions: Use vernier calipers to measure each dimension. Complies with drawing tolerance standards.
5. The thickness of the surface coating is measured with a thickness gauge, and five points are evenly distributed on each side for measurement. Coating thickness >10.
6. Surface hardness: Use a hardness tester to measure, and measure at five points evenly distributed on each surface. HW≧15.
7. All aluminum profiles must be fully inspected. After meeting the requirements, they should be individually packaged, and then packaged in groups of 4. Finally, protective packaging should be done in wooden boxes. Damaged or damaged during transportation.
