  • The coating finish of electrolytic tinplate is high, and the surface of the tin layer after electrolysis treatment is smoother and brighter, which is conducive to subsequent printing, spraying and other fine processing. The tin layer of non-electrolytic tinplate is relatively thick and is usually not suitable for detailed processing.

  • It is difficult to repair deep dents or can deformation caused by large impact or severe extrusion. In this case, the internal metal structure of the tinplate can has changed, and some materials may have cracks or interlayer separation, and external force alone cannot completely restore it to its original state.

  • Common printing processes include offset printing (lithography) and gravure printing. The entire offset printing process is divided into the following steps: 1. Plate making 2. Printing 3. Multi-color printing 4. Baking and shaping Gravure printing engraves tiny grooves on the surface of the printing plate to hold the ink, and then transfers the ink to the tinplate surface by pressure.
