Pressing seal is a common sealing method, which is widely used in various packaging containers such as metal cans and plastic cans. The principle is to use mechanical pressure to tightly press the joints of the can body and the lid together to form an effective seal.

Aerosol tin cans are filled with high-pressure gas. Under high temperature or severe vibration, the can may rupture, causing the contents to spray out, posing a safety hazard.

Physical properties of tinplate sheet ● Density: about 7.85g/cm³, similar to steel. ● Hardness: usually between HR30T 50-80, depending on the composition of the steel base and the processing technology. ● Tensile strength: usually between 300-500 MPa. ● Yield strength: generally 150-350 MPa.

1. Demand analysis The first step in the customization process is demand analysis. Enterprises need to clarify their specific needs for tinplate products, including shape, size, printing pattern, function and other requirements. 2. Design and development 3. Material selection and preparation 4. Mold making 5. Molding processing 6. Surface treatment and printing 7. Quality inspection 8. Packaging and delivery

Tinplate sheet is also used to manufacture aerosol cans, which are commonly used to store and dispense sprays, pesticides, detergents and other chemical products. Aerosol cans need to withstand internal pressure, and the mechanical strength and anti-corrosion properties of tinplate sheet make it an ideal material choice.
