3. Bottle Caps Technology

Die casting: Injecting molten zinc alloy into precision molds under high pressure to form a structurally complex cover in one go is the mainstream technology.
Electroplating: This is the core technology for achieving a gorgeous appearance of metal covers. Coat the surface of the substrate with a layer of metal such as nickel, chromium, gold, palladium, etc., to provide anti-corrosion protection and brilliant color.
Spraying and coloring: PVD (Physical Vapor Deposition) coating, transparent paint spraying (protective coating), or special coloring treatment (such as aging, enamel) can be performed.
Inner lining assembly: A plastic inner liner (inner plug) must be installed inside the metal cover. The inner liner is usually made of ABS or PP, with an embedded elastic gasket (commonly PE or PTFE) inside, which is the key component that directly contacts the glass bottle mouth and achieves airtight sealing.

4. Bottle Caps Principle

Sealing principle: The metal cover itself does not directly provide sealing. Its sealing function depends on the internal elastic lining. When the lid is tightened, the internal elastic gasket is tightly compacted on the glass bottle mouth, causing elastic deformation, filling all micro irregularities, thus forming a gas tight barrier to prevent the volatilization of perfume alcohol and aroma.
Texture Principle (Psychology and Physics):
Weight sensation: Based on the high density of metal, the heavy lid conveys a psychological suggestion of "expensive" and "solid materials" to consumers through touch.
Cooling sensation: Based on the high thermal conductivity of metal, it can quickly absorb the heat of the skin, producing a cool touch, which is an advanced experience that plastic cannot simulate.
