3.1 Enterprises should carry out quality cost management for products. Generally, prevention cost, appraisal cost, internal loss cost and external loss cost items can be set up, and external quality assurance cost items can be added when necessary. In management, the forecasting, planning, accounting, analysis, control and assessment of quality costs should be coordinated and mutually based on each other. Quality cost management can be specifically implemented in the division of labor of the financial, quality control and other departments of the production enterprise. The most appropriate quality cost should be continuously sought to achieve the goal of reducing consumption and increasing efficiency. 3.2 Marketing quality control should be carried out. Predict the product type, grade, quantity, price, launch time and user requirements for product quality required by the market, and submit a product concept report to convert user requirements and expectations into technical documents. Timely collect, analyze, classify, organize and transmit product usage information to serve the improvement of design and management. 3.3 Design review activities must be carried out at each stage of the design process, and quality engineering control must be implemented to ensure product design quality. 3.3.1 Preliminary research should be conducted when developing new products. While determining the advancement and rationality of the plan, the reliability, safety and economy of the product should also be fully demonstrated, and a feasibility study report should be submitted. 3.3.2 Advanced, reasonable and practical quality goals should be formulated for the product. According to the overall quality goals, the technical quality department organizes reliability designers and quality management personnel to conduct research on performance and use environment, and predicts and analyzes the reliability requirements and quality requirements of the product.
3.3.3 According to market research and user needs, demonstration and appraisal of relevant stages of the development process should be carried out. 3.3.4 Before the design is finalized, small batch production shall be implemented, and process review and product quality review shall be carried out. Functional classification shall be implemented for the products with finalized design. Before production is finalized, batch production shall be implemented and the product production line shall be evaluated. A comprehensive review and certification of the products in the production trial stage shall be organized to ensure that the technical documents, process equipment, raw and auxiliary materials and outsourced parts of the product production meet the needs of product production; product performance and economic efficiency and other indicators meet the requirements. 3.3.5 Design changes and design improvements shall be carried out according to the prescribed procedures. 3.3.6 Specific quality monitoring requirements in the design process are shown in Table 1. 3.4 Procurement quality control shall be strengthened and source flow management shall be well managed. 3.4.1 The list of major outsourced and outsourced raw and auxiliary materials and parts suppliers and their monitoring requirements shall be filled in according to Table 2. 3.4.2 The main purchased and outsourced raw and auxiliary materials and parts should be graded according to their importance, and the main quality items should be inspected and accepted before entering the factory. See Table 3 for details.
3.4.3 Carry out good warehouse management, store the purchased and outsourced raw and auxiliary materials and parts according to the specified requirements, and strictly implement the distribution system.
3.5 Strengthen process control, adhere to prevention as the main approach, and implement an effective combination of quality control and quality supervision. 3.5.1 The processes should be graded according to their importance, and the quality characteristics of the process products should be strictly monitored. The quality engineering management of the manufacturing process should be specifically in accordance with Table 4. Factor management shall be carried out for all key processes or important processes that need to establish process control points. Specifically, the cause analysis of quality problems caused by the process should be carried out around the product quality characteristics of the process, and corresponding inspection and control specifications should be formulated for the dominant factors (causes), and the responsible persons should be identified and form 5 should be filled in. 3.5.2 Inspection activities shall be carried out for production equipment in key processes such as cathode powder spraying, precipitation, electron gun mounting, core column manufacturing, and exhaust. The equipment management department of the enterprise shall work with the user department to fill in the inspection requirements according to form 6 and issue them for execution, and set up an inspection record sheet. The operators shall record the inspections truthfully after regular inspections. If there are quantitative contents, specific data shall be recorded. The equipment management department shall strengthen the spot check supervision on the effectiveness of the inspection work. The equipment inspection rate of key processes and the intact rate of key equipment should reach 100%. 3.5.3 Enterprises shall fill in the calibration requirements for key test equipment and measuring instruments used for production line and finished product testing according to form 7 and manage them.
3.5.4 The environmental requirements for key and some important process processing areas shall be in accordance with form 8. 3.6 Strictly inspect finished products and carry out failure analysis. 3.6.1 The enterprise shall fill in the calibration requirements of various analytical equipment according to Table 7 and manage them. When a product fails, an analysis shall be conducted. Specifically, the work can be carried out according to the failure analysis flow chart in Figure 1: 3.6.2 The finished product inspection items, contents, sampling methods, testing procedures, etc. shall be filled in according to Table 9. 3.7 Regularly carry out education and training activities to continuously improve the quality of personnel. The training requirements for special staff shall be in accordance with Table 10. Operators of important processes and other special workers shall be certified before they can take up their posts. 3.8 For abnormal quality information of the product, fill in the quality information card in time according to the type of problem, transmit and feedback to the relevant units, solve quality problems, and form a closed-loop management of quality information. 3.9 Regular process quality audits and product quality audits shall be conducted, and process quality audit record cards and product quality audit record cards (see Table 11, Table 12) shall be filled in in time, and rectification work shall be carried out. 3.10 Control shall be implemented over product delivery, packaging, storage, and transportation, and product after-sales service shall be carried out. 3.11 The enterprise shall establish corresponding rules and regulations for various quality activities and make good implementation. 2
