Outside CMYK Printed Inside Gold-Coated 52mm Empty Aerosol Can

The Φ52mm internally coated aerosol can is built for products that may interact with bare tinplate. The internal coating creates a barrier between the metal surface and the formulation, helping to preserve product integrity, reduce corrosion risk, and support shelf-life stability.

Manufactured by Guangdong Sihai Iron-Printing and Tin-Making Co., Ltd., this format belongs to our Φ52mm necked-in series (height range 98–240mm).

Why Internal Coating

Q: What is internal coating?
A: It is a protective layer applied inside the can, separating the formulation from the bare tinplate surface.

Q: Why would a product need it?
A:

Q: What happens if I don't use internal coating?
A: If your formulation is compatible with bare tinplate, coating may not be necessary. The choice depends on the contents and how they interact with metal.

Q: Can you help decide whether coating is needed?
A: Yes — share your formulation details and we can discuss the appropriate coating specification.

Can Basics

Q: What are the core specifications?
A:

Q: What heights are available?
A: 98mm to 240mm within the Φ52mm necked-in series.

Coating & Finish

Q: Is the internal coating applied to the whole can?
A: The internal coating is applied to the interior surfaces that come into contact with the formulation. Specific coverage can be discussed based on your requirements.

Q: What cone and dome finishes are available?
A: Clear (varnish), white, and gold lacquer.

Q: Can I combine internal coating with a specific finish?
A: Yes — internal coating and external finish are separate choices and can be combined.

Q: Can I print my own design on the can body?
A: Yes — customized iron-printing is done in-house, covering the full can body with your artwork, colors, and safety markings.

Pressure & Valve

Q: What pressure versions are available?
A: Standard: deformation ≥1.2MPa, bursting ≥1.4MPa. High pressure: deformation ≥1.8MPa, bursting ≥2.0MPa.

Q: Does internal coating affect pressure performance?
A: No — the coating is a barrier layer and does not change the can's pressure rating. Pressure version is selected separately.

Q: Can I use standard aerosol valves?
A: Yes — the necked-in opening is designed for standard aerosol valves. Valve fit should be verified with your filling line and components.

Applications

Q: Where is a coated Φ52mm can commonly used?
A:

Production & Quality

Q: What is the production capacity?
A: Cone production runs on 16 fully automatic lines at 320 pcs/min. Dome production runs on 9 fully automatic lines at 900 pcs/min.

Q: How is the coating checked?
A: Internal coating coverage and adhesion are inspected as part of the production process, alongside dimensional, pressure, and leak testing.

Q: How is quality controlled overall?
A: Production follows the can-making flow: slitting → welding → drying → can sealing → leak testing → packaging. All products are manufactured under ISO9001:2015 and GB13042-2008, supported by an independent laboratory and in-house mold development.

Ordering

Q: How is the can packaged for shipment?
A: Pallets or cartons, planned to match your container loading and handling requirements.

Q: What is the delivery time?
A: Lead time depends on order quantity and customization. Short and on-time delivery is supported by automated production lines.

Q: What should I prepare before sending an inquiry?
A: Please prepare the following:

• Target fill volume, or preferred height

• Estimated order quantity

• Formulation details for coating evaluation

• Cone and dome finish (clear varnish / white / gold lacquer)

• Pressure version (standard or high)

• Artwork files or design references

• Packaging preference (pallets or cartons)

• Destination and delivery requirements

Q: Can I request samples?
A: Yes — sampling can be arranged before mass production.

Q: What is the MOQ?
A: Negotiable, depending on specification and order context.
