To ensure the quality of industrial aluminum profiles, we need to control them from the following aspects:Raw material quality control:Select high quality aluminum alloy raw materials to ensure that they meet production requirementsStrict inspection of raw materials, including appearance inspection, composition analysis, hardness testing, etcReturn or reprocess unqualified raw materialsProduction process control:Control melting temperature, time and atmosphere to ensure uniform alloy compositionThe melting process is monitored and recorded in real time, and the parameters are adjusted in timeEnsure the stability of aluminum liquid temperature, flow speed and pressure during the casting process

Strictly control the parameters and speed of the extruder to ensure the size and surface quality of the aluminum profileCheck the appearance and measure the size of the extruded aluminum profile to determine whether it meets the requirementsIndustrial aluminum profile heat treatment and surface treatment:

Aluminum profiles are heat treated to improve their mechanical properties and corrosion resistance

The use of appropriate surface treatment methods, such as anodizing, sandblasting, spraying, etc., to improve the appearance of the product quality and durabilityQuality inspection and control:Appearance inspection, dimensional measurement and mechanical property testing of finished productsRegular maintenance and calibration of production equipment to ensure its normal operationEstablish a sound quality record and tracking system to trace the production status of each batch of productsApplications of statistical Process Control (SPC) :The statistical process control is applied in the production process, and each production control point is divided into quality control point and process control pointThe stability of the production process is evaluated by the control chart, and the satisfaction degree of the production process to various quality requirements is judged by the process ability indexA data acquisition system based on computer network is established to ensure the timeliness of data, and visual production log system is used to facilitate the tracking of quality problemsQuality Management System:Establish quality policies and quality objectives and a system for achieving these objectives, such as ISO9000 family standardsAchieve quality policy and objectives through a range of activities, including quality planning, quality control, quality assurance and quality improvementIt can effectively control the quality of industrial aluminum profiles to ensure that they meet the needs of various application scenarios.
