Core Concepts and Key Technologies

Double-Wall Vacuum Insulation

The primary technology of this beer cup is double-wall vacuum insulation, which drastically reduces heat transfer through conduction, convection, and radiation:

Inner and Outer Stainless Steel Walls: The inner wall is in direct contact with beverages, while the outer wall protects hands from extreme temperatures.

Vacuum Layer: Eliminates air between walls, minimizing heat exchange.

Hammered Exterior Coating: Enhances grip and contributes marginally to structural rigidity.

Thermal Performance:

Cold beverages: 3–5 hours

Hot beverages: 1–2.5 hours

The design ensures consistent temperature retention, even in outdoor or high-frequency usage scenarios.

Hammered Texture Technology

The hammered exterior is more than a decorative element:

Enhanced Grip: Textured surface prevents slippage.

Scratch Resistance: Protects the surface from dents and scuffs.

Premium Visual Aesthetic: Provides an artisanal, high-end appearance suitable for gifting.

The hammer coating can be customized in color and branding, making it ideal for B2B markets and hospitality applications.
