What are the basic functions of quality inspection?

[opi ci]

The function of quality inspection is mainly reflected in the inspection control function, prevention function and reporting function. Therefore, the quality inspector is required to be careful enough to ensure that each product entering the market is qualified. Therefore, the quality inspector should strictly comply with the relevant functional requirements, do his own work and control the safety and quality.

The first function is the check function, which is also the most basic and important function in quality inspection. However, with the progress and development of the times, the means and technology of inspection are also slowly changing, so different companies have slightly different requirements, but their ultimate goal is to ensure the absolute quality and ensure that the products are 100% qualified. The second function is the prevention function, for example, through the measurement and control of process capability to prevent or through patrol inspection to prevent unqualified products. The third function is the reporting function, which requires the quality inspector to report and feed back to the superior leaders in time after finding problems, so that effective remedial measures can be taken as soon as possible.

1. Check function
That is, according to the requirements of technical standards and specifications, carry out multi-level inspection and experiments on raw and auxiliary materials, in-process products, semi-finished products, finished products, equipment, tooling, etc., so as to avoid putting unqualified products into production or transferring them to the next process or leaving the factory, so as to ensure the quality and play the role of “check”. Only through inspection and strict control, can the quality of products be ensured, such as non-conforming raw materials are not put into production, non-conforming semi-finished products are not transferred, and non-conforming finished products are not delivered.

2. Prevention function
The function of preventing and reducing products that do not meet quality standards can be realized through the following activities:
a. First article inspection and patrol inspection.
b. Incoming inspection, intermediate inspection and completion inspection.
c. Measurement of process capability and use of control chart.

3. Reporting function
The reporting function is also the function of information feedback. Record, analyze, master and evaluate the actual quality level of products by recording, analyzing, mastering and evaluating the original data obtained from quality inspection. The report is fed back to the management decision-making department and relevant management departments in the form of report, so as to make correct judgments and take effective decision-making measures. The reporting function provides necessary information for cultivating quality awareness, improving design, strengthening management and improving quality.
