Chromized Lubricated Aluminum for Caps

Last Updated :Mar. 13, 2024

Among the many materials used in the manufacture of bottle caps, aluminum stands out for its excellent properties, being lightweight, corrosion-resistant and easy to form. However, in order to enhance its functionality and ensure seamless performance, aluminum covers often undergo various treatments and coatings. Among them, chromation combined with lubrication creates a powerful combination of durability, beauty and functionality.

The film thickness is 0.5-4um. The film has good adsorption properties and is mainly used as the base layer of the coating. The appearance includes golden yellow, silver, green, etc. Chrome lubrication treatment is often carried out together with DOS oil lubrication process to chromate and Dos treated aluminum covers.

Chromized Lubricated Aluminum for Caps Manufacturing Process

• 1. Choose high-quality aluminum alloy.
• 2. The selected alloy is carefully processed through casting or extrusion technology to obtain the desired shape and size.
• 3. After the aluminum cover is formed, it will undergo a series of surface treatments to enhance its elasticity and enhance its functional properties.

Chromization is the key process in this sequence and involves the deposition of a chromium-rich layer on the aluminum surface. This is usually achieved by immersion in a chromium-containing solution or by electroplating techniques. The chromium layer not only enhances the corrosion resistance of the aluminum but also provides a strong base for subsequent coatings.

After chromating, the cap is lubricated, a critical step to ensure smooth operation during capping and decapping. Apply lubricant evenly to the chrome surface by spraying, dipping or other specialized methods. These lubricants reduce friction, minimize wear, and help seal containers easily.

Haomei Aluminum offers Chromized Lubricated Aluminum for Caps, ideal for manufacturing long-neck wine bottle caps, extra-deep drawn and decorative caps, as well as a range of anti-theft caps for beverage bottles, soft drinks, juices, energy drinks. Chromating or chromating treatments primarily use a conversion coating to passivate the surface of aluminum enclosure panels.

Chromized Lubricated Aluminum for Caps Advantages

• 1. Corrosion resistance: The chromium plating layer forms a protective barrier, effectively resisting oxidation and corrosion, and extending the service life of the bottle cap.
• 2. High gloss: The chrome plating treatment gives the aluminum bottle cap a gorgeous appearance, with high gloss and reflectivity, enhancing the visual appeal of the product.
• 3. Wear resistance: The hardness of the chromium layer is high, making the surface of the bottle cap highly wear-resistant, and it can maintain a beautiful appearance even under frequent use.
• 4. Sealing performance: The chromium-plated aluminum bottle cap forms a good seal when matched with the container, which can effectively prevent the leakage of liquid or gas and maintain the freshness and quality of the product.
• 5. High temperature stability: The chromium layer has high high temperature resistance and is suitable for hot filling or baking processes. It is not easily affected by thermal expansion and contraction and maintains sealing performance.
• 6. Recyclability: The aluminum material itself has good recyclability, and the aluminum bottle cap combined with the chrome plating layer can be easily recycled, which is in line with the concept of environmental protection.

Chrome-plated aluminum bottle caps have been widely used in various packaging applications due to their corrosion resistance, high gloss, and strong wear resistance, and have become an important choice to maintain product quality and enhance brand image.
