Three key points of harness quality management
Wire harness Enterprise quality management needs to systematically collect all aspects of product quality data. Through the establishment of Lean quality management system, analyze the collected product quality data, and carry out quality improvement activities according to the actual situation.
Wire harness The main data required for product quality management include: Production / incoming material / commissioning defect detection statistics, and after-sales market feedback quality problem statistics.
According to the above statistics, the quality management department can query the improvement and treatment of previous key non-performing projects and whether the preventive measures form a closed-loop system.
After the system collects product quality management data, it is more important to evaluate and revise relevant inspection control plans, mainly including incoming material / production / delivery inspection control plans. The documents must specify the inspection items, inspection equipment, inspection standards, sampling quantity and sampling frequency.
1. Incoming inspection control plan.
It refers to formulating the inspection quantity and frequency according to the importance, volume and packaging of the product. For products with high failure frequency, the inspection frequency or quantity must be increased.
For products that cannot be tested, give priority to providing testing methods and equipment to relevant suppliers, or negotiate with the process to design and develop testing tooling.
2. Production inspection control plan.
It refers to the products and processes with key and important features of design and process marks, improve the control and recording of equipment parameters, and improve the control and recording of fixture dimensions.
3. Delivery inspection control plan.
It refers to specifying the test standard and sampling quantity with reference to the items required by the technical conditions.
At the same time, the following work needs to be carried out: measurement system analysis, evaluation of whether the current test equipment / fixtures / methods and personnel quality can meet the requirements. If not, training and improvement must be carried out according to the actual situation to improve the comprehensive strength.
For the testing equipment that is difficult to operate, it is necessary to formulate detailed testing operation instructions and equipment operation procedures, implement the post rotation system, transmission, help and drive, standardize and formulate various relevant testing record forms, formulate relevant quality management systems and reward systems, and carry out relevant training.
Departments involved in quality improvement requirements must participate and strictly implement them according to relevant requirements. For example, E-Valley grants relevant punishment rights to the quality management department:
(1) Set up contact person
It is suggested that each department set up a quality improvement interface. On the one hand, it is conducive to the rapid promotion of improvement measures. On the other hand, it can strengthen the consultation and communication of various departments, hold regular quality meetings and do a good job in relevant prevention work.
(2) Set up suggestion box
Set up quality improvement suggestion boxes in each factory workshop and formulate relevant quality improvement system documents in the early stage. Including how to evaluate the cost of improvement, revenue generation and personal rewards.
(3) Relevant system review
While carrying out the above work, relevant systems shall be reviewed. The improvement of the system must be combined with the treatment process of practical problems to establish a process management system suitable for the company.
(4) Data statistical analysis
Carry out statistical analysis according to the data collected by each inspection point, determine the improvement objectives, formulate the quality improvement plan, and give priority to the implementation of simple, simple and fast projects.
(5) Organizational adjustment
According to the actual work situation, adjust the organization, improve the standardized filing of the project, and hold summary meetings regularly.
