The process of manufacturing aerosol cans is mainly divided into the following key steps: can body forming, nozzle and valve manufacturing, assembly and filling. These steps involve the combination of multiple manufacturing technologies and processes, which will be described in detail one by one below.

As mentioned above, the melting point of the tin layer is much lower than that of the steel. If the tinplate sheet is heated directly, the tin layer will melt before the steel substrate reaches the melting temperature, which will cause the tin layer to be lost and lose its anti-corrosion function.

The coating of tinplate is tin, while the coating of TFS is chromium. This is the most significant difference between the two. The anti-corrosion performance of tin mainly relies on its chemical inertness, while chromium relies more on its chemical stability and the protection of the oxide film.

Specific data shows that China exports more than billions of aerosol cans each year, covering a variety of categories from ordinary household aerosol cans to industrial high-pressure aerosol cans. Among these exports, metal aerosol cans account for a considerable proportion
