The aluminum roll printing & milling anti-counterfeiting bottle cap is a type of bottle cap that incorporates embossing and milling processes to create anti-counterfeiting markings on aluminum caps.

Material

The aluminum roll printing & milling anti-counterfeiting bottle cap is made from aluminum sheets, commonly using alloys such as 1060, 3003, 3105, and 5052, with thicknesses typically ranging from 0.15mm to 0.3mm, with 0.21mm being the most commonly used.

HAOMEI Aluminum uses high-quality aluminum alloy materials, along with FDA-compliant coatings and printing inks, to ensure the quality and safety of aluminum caps. Combined with exquisite embossing designs and advanced milling technology, we provide your products with the most refined crown caps.

Embossing Process

The bottle cap embossing process utilizes high-precision roller molds to apply mechanical pressure, imprinting text, patterns, or anti-counterfeit marks onto the cap surface. This results in permanent embossed or recessed designs.

Mold Design:	The mold must feature clear and intricate patterns to ensure high-quality embossing. Metal molds are used for precision metal stamping.
UV Ink Control	Ink color is adjusted based on customer requirements, ensuring proper ink viscosity for accurate printing.
Uniform Pressure	Pressure tests are conducted before production to ensure consistent embossing quality.
Curing Process	UV Curing: For UV inks, UV lamps are used for fast curing.
Curing Process	Hot Air Drying: For regular inks, temperature and drying time are carefully controlled to prevent ink detachment or cap deformation.
Quality Inspection	CCD vision inspection systems check the embossing depth, pattern integrity, and positioning accuracy.

Milling Process

The bottle cap milling process is a precision cutting technique where a high-speed rotating milling cutter removes material from the surface or side of the cap, forming grooves, micro-text, symbols, or anti-counterfeit markings.

Cap Design	CAD or CAM software is used to design the text or patterns and generate CNC machining programs (e.g., G-code).
CNC Milling	High-speed rotating milling cutters (20,000-60,000 RPM) precisely engrave text or grooves with uniform depth.
Cleaning	High-pressure air blowing or vacuum suction removes milling debris to maintain the cap’s sealing performance.
Surface Treatment	Depending on requirements, post-milling treatments such as polishing, sandblasting, or anodizing enhance durability, oxidation resistance, and visual appeal.

Anti-counterfeiting advantages of roll printing and milling anti-counterfeiting aluminum bottle caps:

Non-erasable, Permanent Anti-Counterfeit Protection: The combination of embossing and milling provides dual-layer security.
3D Embossing + Precision Engraving for Enhanced Brand Recognition: Increases visual depth and premium appeal of the cap.
Multi-Layer Anti-Counterfeiting for Higher Security: Can integrate QR codes, invisible microcodes, and UV fluorescence for enhance protection against counterfeiting.
Ideal for High-End Product Packaging: Particularly suited for premium liquor, spirits, pharmaceuticals, and cosmetics.

Quality Inspection Requirements

Ensure the embossed & milled aluminum anti-counterfeit bottle cap is clean and free from visible defects such as cracks, stains, or bubbles.
Verify that the cap dimensions meet standard specifications, including outer diameter, inner diameter, and overall height.
Test the sealing performance to ensure no liquid leakage and protection against contamination during storage and transportation.
Ensure smooth opening of the cap without cracking or damage.
Confirm that the anti-counterfeit markings are clear and precise. After opening, the anti-counterfeit features should be irreversibly damaged, preventing reuse and counterfeiting.
