The current main products of Shanghai Yibin Company include: forklift tire retreading equipment, truck and bus tire retreading equipment, engineering vehicle tire retreading equipment, aircraft tire retreading equipment, including: vulcanization tank, grinding machine, tread press, rubber winding machine, Tire repairing machines, vulcanized steel rings, tire hot stamping machines, tire repair Tools and other auxiliary equipment. First, the significance of tire quality management The quality of tires and the quality of new tires are an issue that is increasingly valued by the society, because it is not only related to the vital interests of the users, but also related to the economic benefits of the company. Nowadays, various retreading enterprises have enhanced their quality awareness to different extents. Enterprises can only take the road of “survive by qualityâ€. Therefore, it is necessary to improve product quality as an important policy for enterprise development. It is obviously important to carry out enterprise quality management. significance.
In order to do a good job in the quality of tire refurbished products, it is necessary to formulate a set of easy-to-operate quantitative quality assessment system, scientific humanized rules and regulations, and deeply rooted in the concept of "quality first" in the hearts of every employee. In production, the employees imagine the next process as a user, the products flow in turn, the quality layer is closed, and the ring is fastened, thus ensuring that the factory tires are high quality products.
Successful quality management is the pillar to improve the competitiveness of enterprise products. Quality plays a huge role in improving the economic interests of enterprises. Develop the market with quality and stabilize the market with quality. If the quality of the product is not good, there will be no competitiveness and no good economic benefits will be achieved. Production of refurbished tires to meet user needs, production and sales of unqualified products, and provide excellent service. Enterprises can't cut corners in order to pursue profits, and the quality of products will decline. Under no circumstances can the quality of the product be reduced in order to save material.
Quality management not only affects the economic interests and competitiveness of enterprises, but also reflects the comprehensive management and technical level of an enterprise, and also reflects the state of spiritual civilization construction of enterprises. Therefore, work must be carried out around the following points.
1. Promote the ISO9001 quality management system In accordance with the requirements of the ISO9001 quality management system, implement the modern quality management model, strengthen the quality management of enterprises, improve the quality guarantee mechanism, and improve the inspection institutions and functions.
2. Carry out quality statistics and mathematical analysis. Improve the inspection organization and start the three inspection system. All semi-finished products and finished products in the factory shall be fully tested and checked, checked and settled for quality statistics and mathematical analysis, and the quality monthly report shall be published. At the beginning of each month, a quality analysis meeting attended by the company's chief executive, various functional departments and production workshop managers will be held.
3. Conduct employee quality management education Conduct employee quality management education, combine technical theory training and professional ethics education. And let all the people understand that "product quality is quality management. The production process is the object of quality management, and the product is the result of quality management. What kind of quality management will produce what kind of quality products." Therefore, it is required to do a good job of combining software (design quality) with hardware (quality of work). Through "organization, planning, coordination, guidance, inspection and supervision", everyone can consciously regulate their behavior. The purpose of quality management is to enable people in the enterprise not only to do "temporary" and "one thing", but also to do "timely" and "everything", so that the spirit of enterprise and quality are deeply rooted in the minds of employees, so that they are thousands of Repeatedly repeating every small movement in the production operation in accordance with the requirements of the program.
4. Pay attention to the quality of products to prevent the production management personnel from making corrections in quality and production, and making decisions on giving quality. Technicians should be aware that the quality damage that occurs during product use is mostly a matter of technical design quality. Some defects in the finished product that are produced improperly are also related to the poor design of the process. "Congenital deficiency" requires "prevention first", and it is necessary to put a large amount of quality work on product development.
Second, the characteristics of tire repair quality management China's large tire repair companies are relatively few, with fewer modern scientific management companies. There are a lot of small workshop-style enterprises, and the management mode, product quality and process technology are mostly in the low-end state. Little is known about quality management, especially knowledge of total quality management. To establish an enterprise quality management mechanism and carry out quality management work, we must start from the advanced stage of total quality management. First, we must pass the work of “quality inspection stageâ€, mainly equipped with a certain number of inspectors in various key processes (such as Factory, medium-range, tire-measuring and ex-factory) strictly check the post-mortem inspection work, and do a good job in inspection statistics. Analyze the causes of waste products and develop countermeasures.
1. Full-time inspector quality control of customs inspection and group self-inspection and mutual inspection (1) Full-time inspection of retreading full-time inspection and retreading has four quality inspection levels: the quality of the delivered carcass is tested in the factory; honing and cutting And the quality of the semi-finished products after the mating is tested by the medium-term test; the quality of the embryos after the rubber-forming molding is tested by the tire-selecting mold; the quality of the finished products after vulcanization is tested by the factory. In addition to the quality inspection level, it also combines the entire production process process inspection. The rubber compound full-time inspection level has three quick inspection stations for rubber hardness, plasticity and specific gravity. The process inspection of the rubber production process runs through. All inspections or inspections shall be recorded in detail for statistical and assessment purposes.
(2) The self-inspection, mutual inspection and special inspection activities of the group participation establish and improve the "three inspection system", that is, the combination of self-inspection, mutual inspection and special inspection, mutual supervision and mutual complementation, self-inspection and mutual inspection In the case of finished products, there are ingredients that prevent the occurrence of waste. Self-inspection and mutual inspection are the basic work of product quality. The operator or the inspector must carry out self-examination of the finished workpiece. After passing the test, the signature of the construction card can be transferred to the next process. The next process must check and accept the upper workpiece. If the acceptance is unqualified, it will be returned. Process processing. It is a step forward from the mere inspection and the post-mortem.
2. Quality Management of Statistical Analysis Using mathematical statistics methods, from the production site to the design process, the theory of probability and mathematical statistics is widely used to analyze the product quality and process quality. Advocate the combination of preventive inspection and prevention, and control the factors affecting quality in the manufacturing process according to the indicators in the prescribed quality standards.
(1) The full-time inspector of the enterprise shall register the original data of the inspection, and report the monthly report of quality (qualification rate, primary qualification rate, scrap rate, re-return rate, repair rate).
(2) When the quality is abnormally fluctuating, the full-time inspector can timely report the quality abnormal information feedback form.
(3) Do a good job of mathematical statistics and analysis of various quality defects and economic losses in the current month, and classify monthly quality statistics into enterprise files. The mid-inspection, final inspection and inspection personnel participate in the monthly routine quality analysis meeting of the factory: report the quality dynamics, analyze the causes, and propose rectification suggestions.
3. All staff, whole process, and comprehensive quality management to renovate the needs of tire users, pay attention to quality costs, and complete the "statistical quality management stage", enter the application system theory, information theory, cybernetics and more A variety of management methods and means. We will mobilize all employees to participate in quality management and implement comprehensive and comprehensive quality management throughout the entire process.
(1) Quality management of all employees From the leadership of the renovation tire company to each worker, everyone participates in quality management, accepts quality management education, raises awareness of quality responsibility, and firmly establishes “quality first, customer serviceâ€. Thought, use scientific management and methods to improve the quality of their work, and strictly enforce the work responsibility system of managers at all levels and enterprises.
(2) Quality management throughout the process The quality of the retreaded tire product also has a whole process of production, formation and realization. It includes processes from market research, design, production, sales to after-sales service. Therefore, it is necessary to comprehensively manage all aspects of the process of forming product quality to form a comprehensive quality management system. The key is to focus on quality management in the design and manufacturing process, because quality is determined by design and manufacturing, rather than by inspection. The inspection only objectively reflects the status quo of quality according to standards.
(3) Comprehensive quality management is to renovate the quality management of tires throughout the enterprise. Since the functions of quality are scattered in various departments, their work is not short to improve product quality. Therefore, all departments of the enterprise must participate in quality management. In the meantime, in order to carry out quality management effectively, all departments must strengthen organization and coordination, and work together to bring product quality together.
From the perspective of organizational management, it can be divided into upper, middle and grassroots management. The content and focus of each level of activities are different: the upper level focuses on decision-making, and the quality activities of all departments and links in the middle layer are unified and coordinated to ensure the realization of the business objectives of the enterprise; the middle management department must implement the quality decision of the upper level and implement their respective quality functions. To carry out specific business management; the grassroots management department must require employees to act in strict accordance with standards and rules and regulations, and complete specific tasks.
4. Renovation of tire companies should adhere to the "four everything" view (1) All for the user's point of view It refers not only to the users of product sales, but also to the next process is the user of the previous process.
(2) All prevention-oriented viewpoints From the beginning of design, products must be prevented from producing quality defects to ensure product quality, reliability, safety, economy and other quality requirements. Therefore, the seven factors of “personnel, machine, materials, methods, testing, environment, and coordination†are controlled to change “afterwards†into “precautionsâ€.
(3) All viewpoints of using facts and data to speak in quality management should advocate in-depth practice, investigation and research, and be aware of the existing problems. It is necessary to conduct scientific analysis and study the law of quality fluctuations based on the statistical data in the test. Find out the main problems that reflect quality and take timely and effective measures to correct them. Overcome the work style based on impression or subjective arbitrariness.
(4) All points of view according to PDCA cycle The PDCA cycle indicates P plan, D execution, C check, and A summary (handling). It is the basic way of all management work, and is the scientific process for all management work.
5. Renovation tire companies must establish a quality assurance system (1) Develop quality policy, quality objectives, quality plan According to the main problems existing in the company, summarize the business purpose of the company in a concise language. It is necessary to embody its ambitions, inspire people, and seek truth from facts, be practical, and strive to achieve quantification.
(2) To establish a comprehensive management organization 1) The comprehensive management organization is the staff of the upper-level quality management function of the enterprise, and can be formed part-time by the relevant functional departments. The main task is to organize, coordinate, supervise, inspect and synthesize the management activities of relevant departments and levels of the enterprise to ensure the effective operation of quality management.
2) Responsible for writing the enterprise quality plan, supervising and checking the implementation of the plan.
3) Organize quality management education, organize product use effect survey, conduct quality evaluation, and participate in new product identification.
(3) Do a good job in quality management basic work 1) Quality management education. Improve the quality awareness of employees and firmly establish the idea of ​​“quality first, serve the usersâ€. Systematically master the theory and methods of quality management. Enrich your professional knowledge, enhance operational skills, and improve the quality and management of your company.
2) Quality responsibility system. Clearly stipulate the duties and authorities of the enterprise department and personnel at all levels in ensuring the improvement of product quality. Establish a set of assessment and punishment methods and strict management system with quality responsibility system as the main content.
3) Standardization work. The organization implements relevant standards and regulations to produce products that meet the requirements of the standard. Organize the formulation and implementation of internal control standards for enterprises and improve the market competitiveness of products.
4) Measurement work. Establish and improve measurement institutions and metering personnel, improve the measurement management system, and ensure the correct and reasonable use of measuring instruments and instruments. Regularly check the measuring instruments and repair and scrap the measuring instruments and instruments in a timely manner.
5) Quality information work. Establish a quality information center, establish a highly efficient and sensitive quality information feedback system, and accurately collect various quality information and intelligence inside and outside the plant. The quality information should be managed hierarchically, and all the original records in management and production should be done.
6) Quality Management Team activities. The administrative team can be used as a unit to conduct various aspects of the production of the team, various issues, around the company's guidelines, improve quality, reduce consumption, improve economic efficiency and management level, and extensively carry out effective and mass management activities.
