As the words say: Good quality cannot be separated from strict quality control; strict quality control makes good aluminum profiles. As for quality control, we need to start from preparation before production, focus on production and processing, self-testing, a selective inspection of every product, and a full inspection of complex products.
Before production, we should check the drawing requirements from beginning to end so that the parts prone to error are marked and memorized. When processing and production, we should focus on the product, gently handle and measure each size, precision processing, and processing each profile must be rechecked whether it is correct. For batch production of the same size, the first product must be re-inspected, and other products maintain random inspection, and more inspection to ensure a 100% qualified rate for the next process.
The task of the industrial aluminum profile assembly department is to carry out self-inspection and check the drawing and have a comprehensive grasp of every assembly detail and the processing requirements on the way. There should be no carelessness while assembly in strict accordance with the requirements of the drawings. Will be well-organized industrial aluminum profile products self-comprehensive check whether there are omissions and negligence parts. The quality control department conducts a comprehensive spot check and careful inspection of the products with special requirements.
After everything is ok, qualified industrial aluminum products are transported to the packaging department for surface cleaning, finishing, and packaging ready for delivery.
