To ensure the quality of the design, it is necessary to evaluate whether the design meets the functional requirements of the product, check the consistency of design specifications with standards, and validate the innovation and practicality of the design.

Incoming material inspection mainly includes checking material specifications, quantity, appearance, performance, and dimensions, as well as validating quality certificates. This ensures that the raw materials or semi-finished products provided by suppliers meet our quality requirements and standards.

Strict production inspection includes real-time online inspection, comprehensive first-article inspection, periodic sampling inspection, and final inspection. These four steps ensure that the products meet quality standards at each production stage.

Regularly evaluate the quality of products and services, identify existing issues, develop and implement improvement plans, and actively collect customer feedback.
