The use of metal materials has a history of thousands of years worldwide, but the emergence of specific metal materials such as tinplate sheet can be traced back to Europe in the 16th century. Tinplate sheet originated from human demand for metal anti-corrosion treatment.

Manufacturing process of aerosol cans: 1. Preparation of tinplate sheets 2. Shearing and forming 3. Rolling and welding of cylindrical can bodies 4. Stamping and forming of can bottoms and can tops 5. Assembly of can bodies, can tops and can bottoms 6. Coating and surface treatment 7. Valve installation 8. Air tightness and pressure resistance testing 9. Filling and packaging

Factors affecting the quality of tinplate: 1. The quality of the base steel plate 2. The uniformity and thickness of the tin plating layer 3. The bonding strength of the tin layer 4. Surface finish 5. The purity and tin damage of the tin layer

The main uses of electrolytic tinplate: 1. Recycling and purification of metallic tin 2. Recycling and reuse of iron substrates 3. Providing high-quality surface treatment processes 4. Environmentally friendly treatment of waste tinplate 5. Application in metal recycling 6. Reducing energy consumption 7. Producing high-purity tin products 8.
