How to control the quality of outsourced parts in machining enterprises

Controlling the quality of outsourced machined parts needs to be carried out according to the characteristics of their own enterprises. Only when it is targeted, can the effect be remarkable.

1. Strengthen the quality awareness of enterprise leaders
Although the awareness of enterprise leadership is not directly related to product quality, it is one of the key factors affecting product accuracy. Managers of enterprises should establish the strategy of quality first and strengthen the idea of keeping improving. At the same time, leaders should appear from themselves and standardize the scope of responsibility of enterprises.

2. Pay more attention at the initial stage of the product
Many enterprises do not pay enough attention to the initial stage of products in the process of production. So with the error until the completion of product processing, the quality of the products produced will have great problems. Therefore, we need to pay attention to it at the early stage of product manufacturing. The early stage of development and design determines the degree to which the product meets the needs of users. Market research results and economic form analysis are indispensable work contents in the early stage of the product.

3. Improve the content of technical documents of outsourced machined parts
Even mature outsourced parts need trial production, evaluation, evaluation, experiment and other processes. Therefore, it is very important for outsourcing supply to be technically transparent to customers. Especially for the technical documents, technical requirements, inspection process and other contents, we need to communicate in the early stage to ensure the correct understanding.

4. Process quality monitoring
In the process of processing outsourced parts, the whole process tracking should be well controlled at the initial stage, so that problems can be found and improved in time. In the subsequent processing process, it is necessary to conduct quality review and spot check on the production site regularly or irregularly. This has played a supervisory role in processing and can receive products with better quality.

5. Clarify the responsibilities of outsourced processing plants
In order to meet the technical requirements in the ordering process, both parties need to sign a contract or agreement before processing. This document needs to indicate the scope of rights and responsibilities of both parties, determine the liability for breach of contract, and also need to develop an incentive mechanism. At the same time, the outsourced machinery processing plants with many quality problems need to be reviewed again. Combined with the quality standards, determine whether the quality defects are technical or production, and make rectification plans and adopt relevant corrective measures.

The quality control of outsourced machined parts of machining enterprises not only has the above aspects, but also these aspects introduced above are problems that are easy to be ignored in the production process. I hope we can pay attention to them and produce outsourced machined parts that meet the standards, high quality and high precision.
