Aerosol cans are essential packaging solutions for industries like cosmetics, household chemicals, automotive products, and more. But before they’re filled with products, they start as raw materials transformed into precision-engineered containers. At Guangzhou Mijia Aerosol Can,we specialize in supplying high-quality empty aerosol cans for global manufacturers. Let’s explore how they’re made.  

1. Aerosol Can Material Selection: Tinplate VS Aluminum

Empty aerosol cans are typically made from:  

Tinplate(tin-coated steel): Strong, cost-effective, and widely used for industrial products.  

Aluminum:Lightweight, rust-resistant, and ideal for cosmetics, pharmaceuticals, and food-grade products.  

The choice depends on the product’s requirements (pressure resistance, corrosion resistance, weight, and cost).  

2. Aerosol Can Manufacturing Process

Step 1: Metal Sheet Cutting & Cup Formation 

- Large metal coils are cut into small discs.  

These discs are pressed into shallow cups using a mechanical or hydraulic press.  

Step 2: Deep Drawing – Shaping the Can Body

- The cups are stretched and thinned in multiple stages to form a seamless cylindrical can.  

This ensures no weak seams, critical for holding pressurized contents.  

Step 3: Wall Ironing (For Aluminum Cans)

- Aluminum cans undergo wall ironing to achieve uniform thickness.  

- Steel cans may skip this step, depending on design.  

Step 4: Washing & Drying

- The formed cans are cleaned to remove lubricants and metal residues.  

- Ensures a clean surface for coating and printing.  

Step 5: Necking & Flanging

- The top of the can is narrowed (necked) to fit the valve.  

- A flange is added to create a secure seal for the valve assembly.  

Step 6: Internal Coating (Lacquer Application)

- A protective epoxy or polymer lacquer is sprayed inside to prevent corrosion.  

- Critical for products like paints, chemicals, or food-grade aerosols.  

Step 7: External Printing & Decoration

- High-speed printing applies branding, labels, and safety warnings.  

- Options:Offset printing, UV printing, or shrink sleeves for premium designs.  

Step 8: Quality Testing

- Leak testing (pressure checks)  

- Dimensional accuracy (height, diameter, valve fit)  

- Coating integrity(to prevent rust or chemical reactions)
