Industry Challenges
Aerosol can manufacturers face unique challenges where pressure and precision must be carefully balanced. Containers need to withstand internal propellant pressure, while metal materials must support accurate forming and welding.
At the same time, surface quality affects printing results, and components must integrate smoothly with valve and cap systems to ensure reliable performance.

Aerosol Can Manufacturing Process
| Material | Description | Application |
|---|---|---|
| Electrolytic Tinplate | Strong material with reliable surface protection for consistent forming | Aerosol can bodies |
| Tin Free Steel | Chromium-coated steel with good surface properties for coating and forming | Can ends and functional components |
| Tinplate Sheets | Flat material prepared for precise forming and shaping | Aerosol can production |
| Tinplate Coils | Continuous supply material suitable for high-volume processing | High-volume aerosol can manufacturing |
Coil Slitting & Sheet Cutting
In aerosol can production, tinplate coils are slit and cut into precise sheet sizes required for can body manufacturing. This stage focuses on dimensional accuracy and edge quality, which directly affect welding performance and forming consistency. Properly prepared sheets help ensure smooth processing in later steps such as body forming and assembly.
With controlled slitting and cutting, FANWO packing supports stable material flow and reduces variation across production, making it easier to achieve consistent results in high-speed aerosol can manufacturing lines.
Metal Printing & Coating
Aerosol packaging is often the first thing customers notice, making surface finish a key part of product value. From sharp, high-definition graphics to coatings tailored for different formulations, every detail must work together without affecting downstream processing.
FANWO PACKING combines printing precision with coating control to deliver surfaces that look refined and perform reliably. This allows customers to achieve strong shelf presence while maintaining compatibility with forming, assembly, and filling operations across a wide range of aerosol products.
Can Body Welding & Forming
The performance of an aerosol can starts with the precision of body welding and forming. In this stage, flat tinplate is shaped into a cylindrical structure, where seam alignment and forming accuracy must be carefully controlled. Even minor deviations can affect pressure behavior and overall reliability.
Stable welding consistency and controlled forming processes help ensure each can body maintains its shape and structural integrity. The result is a well-formed container that provides a dependable foundation for subsequent assembly and real-world aerosol applications.
Dome & Bottom Assembly
The dome and bottom define how an aerosol can responds to pressure and handling conditions. Their shape and connection influence how forces are distributed throughout the container, helping reduce the risk of deformation.
Accurate alignment and secure assembly are essential to maintain structural balance. When properly controlled, this stage contributes to a stable container structure and prepares the can for valve installation and final sealing.
Valve Crimping & Sealing
Valve crimping and sealing are critical to the safe operation of an aerosol can. In this stage, the valve is securely attached to the container, forming a tight and reliable seal. Even small inconsistencies can lead to leakage or affect product performance.
Proper crimping helps maintain internal pressure while allowing controlled and consistent dispensing. When this process is well managed, the can remains sealed, functional, and stable throughout its entire service life.
