Quality control of new products and samples of corrugated box
Quality control of new products and samples from new suppliers
New supplier refers to the supplier who enters Haier's supply network for the first time. First of all, the sqm center of the testing division should carry out the AQP project at the site of the corrugated box production enterprise. As the management of corrugated box manufacturing enterprises, it is necessary to implement the necessary advanced quality planning, require staff training, provide the necessary technical support documents, carry out the quantity identification of any necessary equipment, ensure the consistency of quality level and material source of new suppliers, and ensure the R & D and control ability of the whole process of the corrugated box from design to production. If the AQP project and corrugated box type test report of this model are complete and qualified, the qualified conclusion will be directly issued on the sample inspection notice, and the corrugated box of this model can be verified by Haier's small batch production. In the future, there is no need to go to the supplier's site to audit the new products of the same kind. It only needs to provide complete type test reports and ex-factory inspection reports to issue a qualified conclusion. If the AQP project is unqualified, the unqualified conclusion will be directly issued on the sample inspection notice, and the supplier quality correction sheet will be issued at the same time. After the rectification is in place, the AQP project will be carried out again.
Quality control of new products and samples from old suppliers
Old suppliers can provide their own AQP data. When applying for inspection of new products and samples, they can provide complete type test reports and ex-factory inspection reports of corresponding types of corrugated boxes. If the data are complete and qualified, they can directly issue a qualified conclusion, otherwise, they will issue an unqualified conclusion.
All new products and samples of corrugated box type test reports are tested by Haier Group laboratory, corrugated box suppliers provide corrugated box samples, type test indicators mainly include bursting strength, puncture strength, edge pressure strength, bonding strength.
Quality control of corrugated box for batch products
Haier has implemented the inspection-free system for corrugated boxes that have been supplied in bulk by old suppliers. Fai is marked on the delivery notice of Haier Group's suppliers. The quality of corrugated boxes supplied in batches is controlled in the production process and the supplier's ex-factory inspection, and there is no need to provide acceptance records when entering the factory. In case of process change of corrugated box process, equipment and materials, product transfer to the new production site, quality problems of inspection free products in-field use, new equipment start-up, and technical change, etc., IQC will be marked on the delivery notice of Haier Group supplier. The supplier will go to sqm Center for new products and sample procedures, and sqm center will inspect corrugated boxes batch by batch for continuous inspection After three batches are qualified, they will be turned into inspection free products.
