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)

1.Stability & Compatibility of aerosol tin can

For any aerosol products, we should first select the cans according to the type of product, the characteristics of the formula to do the compatibility & stability test to ensure the stability of the product. Only through the stability of the test can we let the product into the market.

 

2.Security of aerosol tin can

It Includes the safety of use, pressure safety, environmental safety, safety of independence and the percentage of contents in a full aerosol tin can, etc.

 

3.Comfort of use of aerosol tin can

Any products after production and selling, it will be used by the final consumer. Besides, the comfort of use, ergonomics, spray effect, fragrance concentration, etc., related to the permanence of the existence of the product.

4.The economics of aerosol tin cans

Excessive use of packaging materials, in fact, is type of a waste. Therefore, the choice of packaging materials is an environmental protection.

5.Aesthetic appeal of aerosol tin can

Many consumers, especially cosmetics are outlook picker. Therefore, the first impression often determines the success of the products. And we also need pay more attention to the combination of appearance setting and the aesthetic needs of appropriate groups.

 

[Prologue]

We prepared a set of 2K Aerosol Tin can and other materials, which will simulate the filling and painting process of 2K aerosol spray paint can. Also, we picked our latest 2K Aerosol Tin can as the experimental props.

Experimental materials

1- Two paper cups. 2- A aerosol valve compressor. 3- A bottle of DME propellant gas. 4- The new design 2K Aerosol Tin can. 5- Two different colored liquids (blue and yellow).

Experiment Process

✅ Click to know more about it: 2K Aerosol Can Product LInk

1. Prepare 2 paper cups, one fill the blue liquild, the other one fill the yellow liquild

2. Filling the 2K aerosol tin can (spray paint side)

→pour the blue liquid into spray paint side

→put the spray paint aerosol valve into the can

→use the valve compressor to seal the aerosol valve

→fill the DEM propellant gas into the can

→Attach the nozzle and plastic

3. Filling the 2K aerosol tin can (Curing agent side)

→pour the yellow liquid into curing agent side

→put the aerosol valve into the can

→use the valve compressor to seal the aerosol valve

→Attach the black button and plastic cap

4. Before Mixing

Before mixing, spray blue liquid

5. Mixing process

We need to mix the liquid on both sides (simulating the process of mixing spray paint and curing agent in 2k aerosol tin can).

→Remove the cap

→Put the black button on the ground

→Press the black button (to mix the two liquids)

→Shake the bottle

6. After Mixing

Now we open the other side of the plastic cap, and we can see that the liquid that is ejected turns green, because blue + yellow = green.

Conclusion

Through this simple experiment, we have been able to gain a better understanding of the working principle of Mgaerosolcan 2K aerosol tin can. The ability to keep substances separate until the desired moment and then allow for a controlled interaction is a key feature of this innovative product.  We believe that this double-headed can has great potential in many fields, and we look forward to seeing how it will be utilized in the future.  Stay tuned for more updates and experiments related to our exciting new product!
