Wire harness enterprise quality management requires systematic collection of product quality data in all aspects. By establishing a lean quality management system, analyzing the collected product quality data, quality improvement activities should be carried out according to the actual situation.

The main data required for the quality management of wire harness products include: production/incoming/testing machine defect detection statistics, after-sales market feedback quality problem statistics.

According to the above statistics, the quality management department can inquire about the improvement and treatment of key non-performing projects in the past, and whether preventive measures have formed a closed-loop system.

After the system collects product quality management data, it is more important to evaluate and revise the relevant inspection control plans, which mainly include: incoming/production/outgoing inspection control plans. The documents must specify the inspection items, inspection equipment, inspection standards, sampling quantity and sampling frequency.

1. Incoming material inspection control plan

Refers to the number and frequency of inspections based on the importance and volume of the product. For products with high failure frequency, the inspection frequency or quantity must be increased.

For products that cannot be tested, we will give priority to providing testing methods and equipment to relevant suppliers, and we can also negotiate with the process to design and develop testing tooling.

2. Production inspection and control plan

Refers to the product and process of the key features and important features of the design and process marking, improving the control and recording of equipment parameters, and improving the control and recording of fixture dimensions.

3. Factory inspection control plan

Refers to the project mainly referring to the technical requirements, specifying the testing standard and sampling quantity.

At the same time, the following work is also required: measurement system analysis and evaluation of whether the current test equipment/fixtures/methods and personnel quality can meet the requirements. If it cannot be achieved, training and improvement must be carried out according to the actual situation to improve the comprehensive strength.

For difficult-to-operate testing equipment, it is necessary to formulate detailed testing operation instructions and equipment operating procedures, implement the rotation system, transfer, help and drive, standardize and formulate various relevant testing record sheets, and formulate relevant quality management systems and reward systems. and relevant training.

The departments involved in the quality improvement requirements must participate and strictly implement the relevant requirements. For example, Electronic Valley grants the quality management department the right to punish:

(1) Set up an interface person

It is recommended that each department set up a quality improvement interface person. On the one hand, it is conducive to the rapid advancement of improvement measures, and on the other hand, it can strengthen the consultation and communication of various departments, hold regular quality meetings, and do a good job in related prevention work.

(2) Set up a suggestion box

Set up quality improvement suggestion boxes in each factory workshop, and formulate relevant quality improvement system documents in the early stage. Include how to assess improvement costs, generate benefits, and personal rewards.

(3) Review of relevant systems

While carrying out the above-mentioned work, implement relevant system review. The improvement of the system must be combined with the actual problem processing process to establish a process management system suitable for the company.

(4) Statistical analysis of data

Statistical analysis is carried out based on the data collected at each inspection point, improvement goals are determined, quality improvement plans are formulated, and simple, simple and fast projects are prioritized.

(5) Organization adjustment

According to the actual work situation, the organization is adjusted, the standardized filing of the project is improved, and the summary meeting is held regularly.
