Opinions on rectifying the quality of Masteel casting products in our county

Foundry industry is the pillar industry of our county, which has made important contributions to the economic and social development of our county for many years. At the beginning of the year, the County Foundry Management Office, the Bureau of Quality and Technical Supervision and the Foundry Association jointly tested the quality of 794 batches of pipe fittings produced by foundry enterprises in the county, and the test results were not satisfactory. The qualified rate of the sampling survey of pipe fittings in the county was worrying. It reflects that some foundry enterprises in our county have weak quality awareness, rough production technology, imperfect quality management system and imperfect testing methods, which leads to an increase in the proportion of unqualified products. In order to change this situation, after research, the following suggestions are put forward:

1. Unify thinking and raise awareness. The poor quality of malleable iron pipes directly affects the reputation of our county's malleable iron casting products, market expansion and competition, and even threatens the survival and development of the industry. Formulate the quality control and rectification plan for the casting products of Masteel in our county, the necessary conditions for the production of Masteel casting enterprises and the product quality acceptance standards, and further standardize the production behavior of Masteel casting enterprises in our county. A casting production license will be issued to those who meet the production conditions, and rectification will be made within a time limit if they do not meet the conditions.

second, focus on supporting a number of famous brands.

we should select a group of enterprises and products with stable product quality, high market share, good economic benefits, development potential, obvious energy conservation and consumption reduction, and remarkable environmental protection management to focus on cultivation, and take the lead as a model. The county government shall commend and reward the enterprises that have obtained provincial iconic brand products, provincial famous trademarks and provincial famous brand products and national famous trademarks. All enterprises should actively strive for trustworthy products, high-quality products and inspection-free products, strengthen quality awareness, minimize non-standard production and resolutely put an end to non-standard production. The county government will pay the supervision and inspection fee twice a year for the enterprises that have passed the sampling inspection for three consecutive years. At the same time, the County Foundry Office, the Bureau of Quality and Technical Supervision and the Foundry Association should organize corporate legal representatives, managers and technicians to participate in some professional training meetings, encourage enterprises to change the backward production technology and mode in our county, realize mechanization, automation and intelligence of production, and improve the quality level of foundry products in our county as a whole.

third, establish an enterprise quality management system in an all-round way. At present, most foundry enterprises in our county still use traditional production equipment, and the low level of professional and technical personnel and lack of sound quality management system are another reason for the decline of product quality. In order to change this backward situation, the Bureau of Quality and Technical Supervision should help enterprises to establish a set of quality management system standards suitable for the production level of enterprises in our county, and actively help enterprises to do a good job in quality certification. Promote enterprises to gradually carry out ISO9 quality system certification; Enterprises that do not have ISO9 quality system certification for the time being should update their backward production equipment, equip them with professional and technical personnel, establish their own quality management system according to the standards issued by the county quality supervision department, and realize standardized management.

fourth, shoddy work is strictly prohibited. The quality supervision department should cooperate with the industrial and commercial departments to stop production for rectification within a time limit for enterprises with rough production technology, no testing equipment and personnel and unable to produce according to national standards and enterprise standards, especially those with poor pass rate in this spot check. After rectification, the production can be resumed only after passing the inspection; Enterprises that still fail to meet the standards after rectification shall revoke their business licenses in accordance with relevant regulations and resolutely ban them.

Fifth, strengthen supervision and testing, and establish a long-term mechanism for quality management. County quality supervision departments should rely on Maanshan Iron & Steel Testing Center in Shanxi Province to intensify the sampling inspection of the product quality of casting enterprises in the county, implement hierarchical management of casting enterprises, and award the title of "product quality trustworthy unit" to enterprises with good enterprise management, stable product quality and 1% passing rate of sampling inspection for three consecutive years; Better enterprises should rectify within a time limit, and implement a monthly sampling system, charging according to regulations until the product qualification rate reaches the prescribed standard; Poor enterprises, strengthen supervision and testing, whether from sampling batches or product categories should be expanded; Poor enterprises should send people to check at designated points until the quality of their products is stable and a complete quality management system is established. Enterprises with hidden product quality risks and imperfect quality assurance system should be severely punished according to the Product Quality Law, and the unqualified molds used by enterprises should be resolutely destroyed.

VI. Strengthen supervision over the governance and rectification of foundry enterprises. County quality supervision, industry and commerce departments should increase supervision over the governance and rectification of foundry enterprises. In the process of rectification, we must adhere to the principles of openness, fairness and justice, whether it is product sampling, testing and inspection, or the resumption of production and approval of enterprises, rectify according to law, produce according to law, shut down according to law, and ban according to law to ensure the normal operation of this rectification work. Foundry Association should give full play to the role of the Association in this rectification, especially the enterprises with directors or above, should take the lead in rectification, improve product quality, meet the required standards, and raise the awareness of "revitalizing the county with quality and revitalizing enterprises with famous brands". The industrial and commercial departments should intensify the inspection and crackdown on unlicensed enterprises, standardize the economic order, and maintain fair competition. This time, enterprises should closely cooperate with functional departments, and under the unified leadership of the county government, ensure that the rectification work is implemented and effective.

* * * * * * Strengthening process quality control and improving process management level

Process quality control is the basic point of process quality control and the important content of on-site quality control.

1. Do a good job in process planning to improve the accuracy of process work

Process planning is an important content of process quality control, and it is an important work to ensure that the product quality formation process runs effectively for a long time in a controlled state according to the provisions, procedures and methods of program documents. In order to ensure the quality of the designed products, the technological work must be prepared for a rainy day. At the initial stage of product design and development, we should make the basic planning of product production based on the user's requirements and exceed the product requirements, make a detailed process development plan, fully consider the existing personnel, tooling, equipment, technical ability, logistics, production environment and other factors, clarify the work tasks and responsibilities of each interface department, refine the target values and schedules of each task to each interface department, and inspect and supervise according to the task requirements to ensure that the work tasks are completed according to the specified requirements.

do a good job in process planning, accurately investigate and analyze personnel, tooling, equipment, technical ability, logistics, production environment, etc., and organize necessary process plan design and review, so as to implement the plan with clear objectives and specific measures. Only by doing these pre-planning work accurately can we reasonably organize and carry out comprehensive technological work, improve the accuracy of technological work, reduce blind investment, avoid the backlog of non-performing assets and waste of resources, and improve the economic and social benefits of enterprises.

the quality of process planning is the key to the success of product development. Our company has had lessons of failure and joy of success in this respect. In the past few years, our company has not established an effective process management system, paid no attention to process planning in the process of new product development, lacked the active intervention of process departments, lacked necessary investment in tooling, equipment and process means, and failed to effectively ensure product quality during product trial-production, resulting in frequent cases of new product development failure. For example, in the process of developing automotive air conditioning systems such as Hebei Tianye and Jiangnan Alto, our company failed to carry out the necessary process verification and tooling verification because of poor process planning, and the product quality could not be guaranteed and eventually lost the market. On the contrary, in the process of developing Santana car air-conditioning condenser, evaporator and Fukang car air-conditioning condenser, the process planning was done carefully because of simulating the supplier quality ability audit mode of Shanghai Volkswagen Company and Wuhan Shenlong Company, and a complete development plan was compiled, taking into full consideration the factors of personnel, tooling, equipment, technical ability, logistics, production environment and so on, and a detailed and complete process plan was formulated. The process quality can be effectively guaranteed in the process of sample trial production, small batch trial production and batch trial production, and the product quality can be continuously improved and improved through process control means such as process verification and tooling verification. Therefore, not only the requirements of users are met in the time period of product development, but also the product quality and process quality capability are recognized by Shanghai Volkswagen and Wuhan Shenlong Company.

second, establish process quality control points to improve process quality capability

process quality control is the basic point of process quality control and the important content of on-site quality control. In the process of product quality formation, there are several working procedures, and their definitions are divided into three categories:

(1) General working procedures: working procedures that play a general role in product quality formation;

(2) key processes: processes that play an important and key role in product quality, especially reliability and quality;

(3) special process: the process whose result can not pass the subsequent inspection and test, but can only be completely verified after use.

establish process quality control points, that is, while strengthening general process quality control, take effective control methods to focus on key processes and special processes to ensure that the processes are always under control. The main work includes the following aspects:

(1) Establish process quality control points according to relevant principles, compile key process control point tables in process documents, list important control parameters and control contents, and clearly mark key processes and special processes with special seals;

(2) Set up a signboard at the production site, with the deputy technical director of the workshop responsible for the daily work of the control point, and the project manager in charge of products in the process department responsible for supervision and spot check;

(3) Prepare process regulations and work instructions, and put forward specific technical requirements for personnel, tooling, equipment, operation methods, production environment and process parameters;

(4) Important process parameters and characteristic values of process documents must be evaluated or verified;

(5) The operator must strictly abide by the process discipline, conduct the first inspection and self-inspection in time, and keep the original production records, which shall be checked and confirmed by the person in charge of the control point;

(6) The inspectors must carry out inspections in strict accordance with the process regulations and inspection instructions, make original inspection records and report them to the Quality Supervision Department every week;

(7) The person in charge of the quality control point must insist on daily inspection and collect original records, and use statistical techniques such as questionnaire, control chart and causal chart for statistical analysis and monitoring;

(8) Production equipment, inspection and test equipment, tooling and measuring instruments must be in good condition and under control.

when it is found that the control method of process quality control points can't meet the requirements of process capability, the person in charge of control points should immediately report to the process department, which should organize relevant personnel to analyze, improve and improve, so as to ensure that the process is under control and make the process produce qualified products stably for a long time.

Third, strengthen the process quality audit and improve the level of process management

Quality audit is a systematic and independent quality work to verify whether the quality activities meet the planned arrangements and whether the results can reach the expected goals. The external quality audit of an enterprise is the authoritative certification of a third-party quality system certification institution represented by ISO9 quality system certification and the quality capability certification of suppliers. Internal quality audit is a series of quality activities with internal quality system audit, process quality audit and product quality audit as the core.

process quality audit is the focus of internal quality audit, and its purpose is to verify whether the factors affecting the production process and its control methods meet the requirements of process control and process capability, find existing problems in time, and take effective corrective or preventive measures to improve and improve, so as to ensure that the process quality is in a stable and controlled state.

to strengthen process quality audit, we should refer to the mode of ISO9 quality system certification and supplier quality capability audit of Shanghai Volkswagen, Wuhan Shenlong and other companies, focus on key processes and special processes, and conduct a comprehensive audit with many factors affecting process quality. Therefore, we must do the following work well:

(1) Organize the process quality audit in a planned way, and make specific arrangements for the content, time, frequency and personnel of the audit, generally not less than twice a year;

(2) check whether the technical level and business ability of existing personnel meet the requirements of process quality control;

(3) review the product quality of outsourced parts, outsourced parts and raw materials and the quality capability of subcontractors, and conduct regular quality follow-up review and comprehensive evaluation on the audit mode of Class A matching parts simulating Shanghai Volkswagen Company;

(4) Check the correctness, completeness and operability of process regulations and work instructions. Important parameters and characteristic values of process control must undergo process evaluation or process verification, and there are documented process evaluation books or process verification books;

(5) The storage, packaging, handling and labeling of raw materials, semi-finished products and products must comply with the provisions of the procedure documents, and there shall be no bump, damage or deterioration;

(6) Check whether the intact rate, exclusive rate and periodic inspection rate of production equipment, inspection and test equipment, tooling and measuring instruments meet the quality requirements of process control;

(7) Focus on reviewing the process quality capability, quality records and statistical analysis results of the process quality control points;

(8) review the quality of work of various interface departments, and the interface departments should have continuity and stability;

(9) Use mathematical statistics technology, process FMEA and process FMEA to analyze process capability and defects, find out the problems existing in process quality control, and take effective corrective or preventive measures to continuously improve and improve process quality capability.

process quality audit is one of the important means to continuously improve and improve product quality, which can promote the production workshop and solve some practical problems. Such as Santana car air conditioning steam produced by our company.
