1 Overview
Quality is a broad concept, which refers not only to product quality, but also to the quality of a certain activity, process and system; quality is the guarantee of aluminum profile products and the life of an enterprise; the operation techniques and activities adopted to meet quality requirements are called For quality control; that is to say, the quality control of aluminum profiles is to monitor the quality formation process, eliminate the factors of unqualified or unsatisfactory results in all stages of the quality link, in order to meet the quality requirements and obtain economic benefits, and various quality Operation technology and activities; aluminum profile quality management is a series of management activities based on the quality management system; in the field of enterprises, quality control activities are mainly the production site management within the aluminum profile production enterprise, which has nothing to do with whether there is a contract or not. Refers to the activities in terms of technical measures and management measures to achieve and ensure the quality of aluminum profiles;
2. Aluminum profile quality control method
(1) Quality management system
At present, the international quality management system of aluminum profile products is ISO9000 family; the definition of quality management system is: a system that establishes quality policy and quality objectives and achieves these objectives;
The role of the quality management system has two points: one is to establish the quality policy and quality objectives; the other is to achieve the quality policy and objectives through a series of activities, these activities are mainly quality planning, quality control, quality assurance and quality improvement;
(2) Quality assurance system
Quality management develops with the development of the whole social production; after the human society begins to have production practice activities, there will be quality management problems; quality management has generally gone through three stages: inspection quality management, statistical quality management and total quality management;
1) On-site quality management
In a narrow sense, on-site quality management refers to the management of the first line of production; all production sites that achieve the quality of aluminum profiles from the entry of raw materials to the warehousing of finished profiles are called sites; the purpose of on-site quality management is to achieve aluminum profiles. The requirements specified by the profile products; the on-site quality management mainly includes four aspects: the whole process quality control, the production factor control, the quality information feedback control and the non-conforming product control;
① Whole process quality control
The whole process quality control of aluminum profile production (T·Q·C) is to control the quality of the entire production process of aluminum profiles, and comprehensively supervise whether the aluminum profiles are produced according to the original design plan, and whether the products meet the specified quality requirements; the most important of which is Process quality control, especially the quality control of key processes and key processes;
②Control of production factors
The stability of production factors directly affects the quality of aluminum profile products. The control of production factors is essentially to control all factors affecting the quality of aluminum profile products, including equipment, personnel, raw materials, process regulations and parameters, etc., to achieve the stability of factors;
③ Quality information feedback control
The establishment of quality information feedback is to realize the rapid and effective transmission and timely processing of quality information in the aluminum profile production site, so as to ensure the normal and orderly operation of the quality system; it requires the formation of a closed-loop feedback mechanism from discovery, processing to effect confirmation. Occurred or potential quality problems are dealt with quickly;
④ Control of non-conforming products
The aluminum profiles that are judged to be unqualified products after inspection and testing must be marked, recorded, evaluated, isolated, handled and notified; the most important thing is to carefully self-inspection, mutual inspection and special inspection in the production process of aluminum profiles. Strictly test and supervise aluminum profiles with advanced testing methods, means and instruments to ensure that aluminum profiles meet the requirements of technical standards;
2) PDCA cycle
PDCA cycle is a scientific work method that quality improvement and other quality management work should follow; quality improvement is committed to improving the effectiveness and efficiency of products, processes and systems; total quality management requires enterprises to continuously carry out quality Improvement activities to enhance the competitiveness of aluminium profile products;
The PDCA cycle includes four stages: plan, execute (do), check (check), and act (act).
