Core Concepts and Key Technologies

Double-Wall Vacuum Insulation

The key technology behind this beer cup is double-wall vacuum insulation, designed to maintain beverage temperatures for extended periods:

Inner and Outer Stainless Steel Walls: The inner wall contacts beverages, while the outer wall protects hands and preserves external aesthetics.

Vacuum Layer: Removes air between the walls, minimizing thermal conduction and convection.

Hammered Exterior Coating: Provides improved grip and adds structural reinforcement.

Thermal Retention:

Cold beverages: 3–5 hours

Hot beverages: 1–2.5 hours

This design ensures beverages remain hot or cold even in challenging outdoor conditions.

Hammered Texture Coating

The hammered exterior is a defining feature of this tumbler:

Grip Enhancement: Textured surface prevents accidental slippage.

Scratch and Dent Resistance: Protects the cup in high-use environments.

Premium Visual Appeal: Offers an artisanal, silvery finish suitable for high-end gifting.

The hammered texture can be customized for branding or color, adding versatility for corporate or promotional purposes.
