3. Bottle Caps Technology

Die-casting technology: Utilizing precise molds for metal die-casting to ensure that the bottle cap has a complex shape and precise dimensions. 
Surface treatment technology: Utilizing PVD (Physical Vapor Deposition) vacuum electroplating technology, the coating becomes more wear-resistant, corrosion-resistant, and has a brighter and longer-lasting color. It also includes spraying, electroplating, oxidation, and laser treatment, among others. 
Magnetic Adsorption Technology: Some high-end bottle caps are equipped with neodymium magnets. Through magnetic force, they achieve precise and smooth adhesion and separation with the bottle body, providing an excellent feel. 
Precision Injection Molding Technology: This technology is used to manufacture internal plastic seals, ensuring a perfect fit with the glass bottle opening.

4. Bottle Caps Theory

The core working principle is  physical sealing  and (optional)  magnetic attraction : 
Sealing principle: The elastic plastic plug inside the bottle cap (usually made of PE or PP) will closely adhere to the neck and inner side of the glass bottle opening when the bottle cap is tightened or pressed, forming a physical barrier that effectively blocks air circulation and prevents the fragrance from evaporating. 
Magnetic attraction principle (if applicable): A magnet is embedded in the top of the bottle cap, and another magnet is embedded in the metal ring or metal plate at the bottle mouth. Utilizing the principle of opposite poles attracting each other, when the bottle cap approaches the bottle opening, the magnetic force will automatically guide the bottle cap to close precisely and provide a stable adhesion force. When opening, a certain vertical force needs to be applied to overcome the magnetic force, resulting in a unique and high-end feel.
