对生产、使用中出现的多起因多余物导致的质量问题的原因进行了分析,探讨了如何控制多余物和提高产品的可靠性。原材料、生产环境、工艺控制、检验手段和人员水平是控制多余物产生的主要因素。在实际生产中通过加强原材料的检验和筛选,改进生产环境条件和完善规章制度,优化产品的工艺设计,合理进行工序布局,提高操作和检验人员技术水平以及增加检验手段等措施,有效地剔除了产品中的多余物,减少了多余物带来的质量问题,保证了产品在使用中的高质量和高可靠。
The causes of the quality problems caused by many causes of redundancy in production and use are analyzed, and how to control the excess materials and improve the reliability of the products are discussed. Raw materials, production environment, process control, testing methods and staffing level are the main factors that control excess material production. In the actual production, measures such as inspection and screening of raw materials, improvement of production environment and improvement of rules and regulations, optimization of product process design, rationalization of process layout, improvement of technical level of operators and inspectors and increase of inspection means were effectively eliminated The excess material in the product reduces the quality problems brought by excess material, and ensures the high quality and high reliability of the product in use.
