Crimped Aluminum Cap

A crimped aluminum cap, as the name suggests, refers to a sealing method where the edges of the aluminum cap are curled. Typically made from 3105 aluminum coils (Haomei products), this sealing method is widely used in food cans, beverage packaging, liquor bottle caps, and some cosmetic and pharmaceutical packaging. The crimped aluminum cap is formed by curling and interlocking the rim of the cap with the flange of the container, ensuring the airtightness and integrity of the packaging.

Features of Crimped Threaded Aluminum Cap

1.Excellent Sealing Performance: The crimping process ensures a tight fit with the bottle opening, effectively preventing liquid leakage, gas evaporation, or contamination.

2.High Durability: Made from aluminum alloys (3015/1060), these caps are corrosion-resistant and wear-resistant, making them suitable for transportation and storage without damage.

3.Easy to Open: Some crimped aluminum caps come with easy-pull rings or notches for consumer convenience when opening.

4.Aesthetic Appeal: The surface can undergo polishing, spraying, or printing treatments to enhance the product's visual quality.

5.Anti-Counterfeiting Function: Laser engraving, QR codes, and other security features can be added for anti-counterfeiting purposes, making them ideal for premium liquor and other high-end products.

Applications

• Liquor Industry: Used for sealing liquor bottles to preserve flavor and prevent evaporation. Premium liquors often feature anti-counterfeit crimped aluminum caps.

• Beverage Industry: Applied to carbonated drinks, fruit juices, beers, etc., ensuring airtightness and portability.

• Pharmaceutical Industry: Used to seal medicine bottles to prevent moisture and contamination.

• Cosmetics Industry: Commonly used for perfumes, serums, and other high-end cosmetic packaging.

Threaded Aluminum Cap Production Process

1.Stamping & Forming: The aluminum material is stamped into the basic cap shape.

2.Crimping Process: A crimping machine curls the edges of the cap to create a secure fit with the bottle opening.

3.Surface Treatment: Polishing, spraying, and printing processes are applied to improve appearance and quality.

4.Anti-Counterfeiting Treatment: Laser engraving, QR codes, and other security features are added for authenticity and protection.
