　　In terms of precision production processes, every rectangular metal tin storage box is manufactured through multiple standardized and precise working procedures with strict quality control throughout the whole process to guarantee product quality from the source. First of all, high-quality original tinplate materials are strictly screened, eliminating inferior plates with uneven thickness and impurities, ensuring firm and uniform texture to lay a solid foundation for the product’s compression resistance, rust resistance and oxidation resistance. Then, numerical control precision cutting is adopted to form standard rectangular outlines without size deviation or skewed edges, ensuring a neat and unified box shape. Afterwards, all-round polishing is carried out on edges, joints and inner walls to remove burrs, sharp corners and rough cuts, presenting a smooth and safe touch.

　　After basic forming, the product undergoes anti-corrosion and sealing treatment with high-temperature cured eco-friendly coatings to achieve multi-layer protection against rust, oxidation and corrosion. It meets safe storage standards with no harmful substances precipitated. Finally, double inspection by machines and manual workers is implemented to check the flatness, opening and closing fluency, sealing tightness and surface condition one by one.
