Regarding product quality, we have a complete control system, and we have signed product technical manuals and quality control manuals with suppliers before signing contracts. See below,

For supplier management, we also have a complete system. For the suppliers we have worked with, we also list them as five levels:

Level 1 (sustainable cooperation, excellent workshop management, perfect finished products, excellent quality) Products, high degree of cooperation, skilled technology, positive values of the company), two (except for the degree of cooperation, the rest are intact, if the improvement of sustainable cooperation), three levels (more than two points below three points need to be improved, If the hard condition is not up to standard, go directly to the five-level supplier) and the fourth level (more than three points and five points or less need to be improved. If the hard condition is not up to standard, then directly enter the five-level supplier, if it is continuously improved to the best The status can also enter the secondary supplier, and then consider whether it meets the requirements of the first-tier supplier after the consideration), five (eliminate, enter the blacklist, and then improve and no longer cooperate)

The management of these five-level suppliers helps us manage our suppliers in real time. Before signing a contract with a supplier, a separate non-compliance agreement or non-competition agreement is required, even if the supplier has cooperated, it is necessary to sign these two agreements.
