A.well-equipped raw material laboratory to test all incoming raw materials as the first step of our quality control process.
B.Each production machine is attended by a professional to test the semi-finished products.
C.After the products are hardened, physical and performance tests are carried out on samples at a certain ratio. For all orders, samples are retained and test records are filed, allowing each batch of contracts to be made retrievable.
D.Each product is visually inspected prior to packaging to achieve zero-defect packaging and storage
