This shows that at the present time when China’s food safety is in serious crisis, the new regulations put quality and safety at a higher level. As the organizer and coordinator of the industry quality work, China Machine Tool Association is responsible for coordinating the strength of the entire industry, building a quality management innovation platform, and exploring the historic mission of the characteristic quality management model.
Improve the quality level from the source
This year coincides with the 30th anniversary of the implementation of total quality management in the machinery industry. Yu Zhen, president of the China Federation of Machinery Industry, said at the conference that the comprehensive improvement of quality management over the past 30 years has effectively promoted the development of the machinery industry. In the past 30 years, the total output value of China’s machinery industry has grown by more than 170 times and exceeded 7 trillion yuan; the industrial added value has increased by more than 180 times to 188 billion yuan; the total volume of foreign trade of the machinery industry has increased by 739 times, reaching 192.9 billion U.S. dollars. Economic development and enhancement of comprehensive national strength have made important contributions.
By 2020, more than 90% of China's major industrial products will be organized according to international standards or advanced foreign standards, and the key issues of major technology and equipment will be basically solved. The reliability will be significantly improved, and the safety, economics, and other indicators of key technology products will be close to or To reach the average level of developed countries, more than 40% of product varieties reach the advanced level of the contemporary world. The reliability and average life expectancy of key products such as CNC machine tools, important basic parts, and internal combustion engines have been significantly improved to meet the needs of the national economy's basic industries and industrial production equipment.
Yu Zhen pointed out that in the future, the machinery industry must pay more attention to the modernization of quality management concepts, realize the reform and development of enterprises in thinking reform, and adopt more powerful measures to improve the quality and efficiency of enterprise development. China's machinery industry should firmly establish the "quality first" idea, and further promote the concept of advanced quality management, adhere to improve the quality level from the source, improve product quality as each employee's sacred duty and historical mission. The "Sanlu" milk powder incident reflects some shortcomings of China's system and mechanism. Now that the State Council has decided to abolish the food quality exemption inspection system, it is to further reform the system, improve the system, and strengthen supervision.
Yu Zhen further pointed out that the machinery enterprises must establish a sound quality assurance system for the entire life cycle of products based on the social responsibility of producers and operators, the internal management of the company's science, and the strict self-discipline of the industry, and strengthen the “big quality†culture. Construction, implementation of the "Excellent Performance Evaluation Criteria" standard, and strive to create a number of well-known companies with international competitiveness.
Zhang Weide, president of the China National Machine Tool Association, said that the China National Machine Tool Association will continue to do a good job in product quality improvement, first promote the change in the concept of quality of the company’s managers, guide the company to formulate and implement a quality management strategy, and pay third attention to product value extension. IV. Cultivate brands with independent intellectual property rights. Fifth, implement quality control in the business process. Sixth, use quality culture as the cornerstone to deepen modern enterprise management. The new Council of China Machine Tool Association will focus on the evaluation of quality-focused awards, so that the “Dual Generation Conference†will maintain well-known domestic brands and gradually participate in international activities. It will stick to reliability-centered academic research and solve the machinery industry. The focus and difficulty of the quality problem form a series of high-quality textbooks focusing on the “Quality Management of Mechanical Industryâ€.
Explore the characteristic quality management model
Not long ago, the China National Machinery Industry Federation conducted a nationwide survey on domestically produced equipment. Users reported that the biggest problems of domestic equipment were concentrated on reliability, stability (preservation of accuracy and maintainability of functions) and pre-sales service. Yang Xuetong, deputy chairman of China National Aircraft Federation, stated that through the “Sanlu†milk powder incident, how to improve China’s quality assurance and quality management system is worth pondering. The work of quality management concepts, theories and practices that are suitable for China’s national conditions and suitable for the actual conditions of China’s machinery industry should be focused on implementation.
Yang Xuetong believes that experience shows that a modern management model full of national characteristics is not only an objective requirement for the development of enterprises, but also an important part of constructing the country's soft power. It is imperative to find and explore a quality management model with Chinese characteristics.
Yu Zhen believes that some companies have boldly introduced, absorbed, and borrowed from the advanced quality management models of industrialized countries, and gradually formed a quality management model that suits China's national conditions and the level of productivity development. The valuable experience of these companies must be carefully and systematically summarized and improved. The China National Machine Tool Association will begin a sample survey of enterprises from this year, and will conduct special investigations and topical summaries each year to strive to enhance the company’s successful experience into a quality management model with Chinese characteristics, industry characteristics, and the spirit of the times.
Zhou Jian, deputy inspector of the Department of Technology of the Ministry of Industry and Information Technology, said that the quality work of the machinery industry should focus on solving outstanding problems that currently affect industrial development, solve the current social concerns, and the problems that the masses are facing, and seek practical results. Management differs from technology and is largely related to the country’s development base and its own culture. Our country must find suitable quality management methods while learning advanced foreign experience according to its own situation. Quality management of the machinery industry should pay attention to summarizing its own management experience.
Promoting Quality Management, Innovating Machinery Industry, Exploring New Features
On October 13th, at the Sixth Member Congress of the China Machinery Industry Quality Management Association (hereinafter referred to as the China Machine Tool Quality Association), nearly 200 representatives of the machinery industry passed the new constitution of the board of directors. Among them, the new statute changed "to sum up the advanced experience of quality management and exchange" to "strengthen the contact and coordination with regional quality organizations, guide and promote the development of quality work in the machinery industry in all regions. Strengthen cooperation with professional associations in the machinery industry We will jointly advance quality management work, strengthen ties with domestic research institutes and quality workers, and organize the research and exchange of quality management theories, techniques, and methods."
