In the past decade, the highest price of tin reached 15,000 per ton, with a large price fluctuation range. This may have a significant impact on the production costs of tinplate manufacturers and affect the overall profitability of the industry.
3. Production Process
3.1 Steel Substrate Preparation
The production of tinplate begins with the selection of high-quality steel substrates. Usually, the steel is first cold-rolled to the required thickness and flatness. Cold-rolling improves the mechanical properties of the steel, making it more suitable for subsequent processing. After cold-rolling, the steel sheet may undergo annealing treatment to relieve internal stress and improve its formability. Currently, about 70% of steel substrates globally are produced by the continuous cold-rolling process, which features high production efficiency and stable product quality.
3.2 Tin Coating
There are two main methods for applying the tin coating to the steel substrate: hot-dip tinning and electro-tinning.
- Hot-dip Tinning: In the hot-dip tinning process, the steel sheet is immersed in a bath of molten tin. The tin adheres to the surface of the steel, forming a thick and uniform coating. This method is relatively simple and cost-effective, but it is relatively difficult to precisely control the thickness of the tin coating. Currently, the tinplate produced by the hot-dip tinning process accounts for about 30% of the global total production, mainly applied to mid-to-low-end products with less strict requirements for the accuracy of the tin layer thickness.
- Electro-Tinning: Electro-tinning is a more advanced method. In this process, the steel sheet is placed in an electrolyte solution containing tin ions. When an electric current is passed through the solution, tin ions are deposited on the surface of the steel sheet, forming a thin and uniform tin coating. Electro-tinning allows for precise control of the tin coating thickness, and the quality of the tin-coated surface is better, making it suitable for high-end applications. The tinplate produced by the electro-tinning process accounts for about 70% of the global total production and is widely used in fields such as food cans and high-end beverage cans.
3.3 Post-treatment
After tin coating, the tinplate may undergo post-treatment processes such as chromate passivation and oiling. Chromate passivation forms a thin, invisible film on the surface of the tinplate, which further improves its corrosion resistance. Oiling is used to prevent the tinplate from rusting during storage and transportation and also improves its lubricity during subsequent processing, such as stamping and drawing. Approximately 90% of tinplate products undergo chromate passivation treatment during the production process, and oiling treatment is applied to almost all tinplate products.
