In the quality control of purified aluminum profiles, the following measures can be taken:

Raw material quality control: The quality control of aluminum profiles begins with raw materials. Aluminum alloy materials with high purity and low impurity content need to be selected as raw materials to ensure that the physical and chemical properties of the product meet the requirements

Production process control: In the production process of aluminum profiles, it is necessary to strictly control the various process links, including melting and casting, drawing and extrusion, surface treatment, etc. This includes the control of melting temperature, melting time, casting process parameters, as well as extrusion temperature, extrusion speed, extrusion ratio and other parameters to ensure the accuracy of product size and good surface quality

Surface treatment control: The surface treatment process of aluminum profiles, such as anodizing, spraying, etc., requires strict control of the composition and treatment time of the treatment liquid to obtain good surface quality and corrosion resistance

Temperature and pressure control: It is necessary to control the appropriate temperature and pressure during the production process to ensure the quality of the product. Too high or too low temperature will have an adverse effect on the performance of aluminum profiles

Time control: Reasonable control of the time of each process can ensure the quality and performance of the product

Quality and inspection: carry out various inspection, including metallographic microscopy, tensile test, hardness test, chemical composition analysis, etc., to ensure that the product quality meets the requirements

Quality management system: Establish and implement ISO9000 quality management system, and achieve quality objectives through quality planning, quality control, quality assurance and quality improvement activities

PDCA cycle: Follow the PDCA cycle for quality improvement, and constantly carry out quality improvement activities to enhance the competitiveness of aluminum products

On-site quality management: including the whole process of quality control, production factors control, quality information feedback control and unqualified product control, in order to achieve the requirements of aluminum products

Strengthen the later quality inspection work: further quality inspection of the extrusion processing tools of aluminum profiles, determine the line cutting margin, try to control the error within the range, and work to be carried out in real time to avoid defects in the actual processing.

Heat treatment process improvement: The aging treatment part and the heat treatment part of the aluminum profile are improved to reduce the risk of hot cracks.
