Quality inspection is an indispensable step in the production process of alloy foot buttons. Raw material testing, button testing, tensile testing, salt spray testing, color fastness testing and color difference testing require that each product go through a Road quality inspection can perfectly pass all kinds of harsh quality and quality certifications at present, winning the trust and recognition of major customers and manufacturers.
Most of the buttons used in middle-to-high end clothing must be tested for salt spray. The so-called salt spray test refers to a kind of artificial simulated salt spray environment created mainly by using salt spray test equipment to examine alloy foot buttons. Or alloy emergency corrosion resistance environmental test. It is mainly divided into two ways: natural exposed salt spray detection and artificial accelerated salt spray detection. Our factory mainly uses more demanding artificial accelerated salt spray testing. The testing workshop is equipped with a professional salt spray test chamber. The salt spray environment is artificially produced in a closed container, which is several to several times higher than the natural environment's salt spray concentration. The speed of corrosion is greatly accelerated, and the corrosion process that may take one year in a natural environment is shortened to 24 hours, which greatly saves the inspection time. The test results will be described in terms of corrosion characteristics, corrosion area percentage, corrosion rate, and corrosion weight increase and decrease. Many methods simultaneously ensure the accuracy of the test. The test data will be measured in accordance with international methods. All non-conforming product batches will be voided to ensure that each alloy pin delivered to customers is the best button!
