The high quality of machines should start from the source, and for stainless steel, which is particularly important for machine equipment, we only cooperate with suppliers who have undergone strict certification and have high-quality production capabilities. During the procurement process, not only is the chemical composition and physical properties of the steel strictly tested, but also the supplier's production site is thoroughly inspected to assess their production process and quality control system.

In order to ensure the quality stability of raw materials, sheenstar has established a comprehensive raw material inspection system. After each batch of raw materials arrives, they must undergo layers of inspection by professional inspectors.
