Designed to accommodate hot and cold beverages, this double-wall stainless steel Tumbler ensures temperature retention while delivering a distinctive aesthetic that differentiates it from standard drinkware.

With increasing interest in premium reusable drinkware, the 9oz hammered beer cup is ideal for hospitality, promotional use, and personal enjoyment, offering both functionality and style. Its compact design is convenient for daily office use, home gatherings, and outdoor events.

Core Concepts and Key Technologies

Double-Wall Insulation

The core technology of the 9oz beer cup is double-wall vacuum insulation, which minimizes heat transfer through conduction, convection, and radiation:

Inner and Outer Stainless Steel Layers: The inner layer holds beverages safely, while the outer layer protects the user from temperature extremes.

Vacuum Layer: Removes air between walls, significantly reducing heat transfer.

Hammered Exterior Finish: Not only adds aesthetic value but also slightly increases structural rigidity.

Performance Metrics:

Cold beverages: maintain temperature for 3–5 hours

Hot beverages: maintain warmth for 1–2.5 hours

Double-wall technology ensures consistent thermal performance, whether the cup is used indoors or outdoors.

Hammered Coating Technology

The hammered coating exterior is more than decorative; it serves several functional purposes:

Enhanced Grip: Textured surface prevents accidental slipping.

Scratch Resistance: Reduces visible wear and maintains appearance over time.

Premium Aesthetic: Reflects light and provides a distinctive artisanal look suitable for gifting or hospitality use.

The hammered finish can be customized in color or branding, making it ideal for B2B applications.

Product Structure, Materials, and Manufacturing

Structural Composition

The 9oz beer cup is composed of multiple engineered components:

Inner Liner: Food-grade stainless steel (SUS 304 or 316) ensures beverage safety and resists corrosion.

Outer Shell: Hammered stainless steel provides durability and visual appeal.

Vacuum Insulation Layer: Maintains temperature by creating a near-complete vacuum.

Base: Flat and stable, designed for balance on uneven surfaces.

Optional Lid: BPA-free silicone or polycarbonate lid to reduce spillage and enhance thermal retention.

Material Selection

SUS 304/316 Stainless Steel: Offers corrosion resistance, durability, and taste neutrality, crucial for beer and other beverages.

Hammered Coating: Provides texture, visual differentiation, and scratch resistance.

BPA-Free Lid Materials: Ensures safe contact with beverages and maintains hygiene.

Material choice directly influences thermal retention, longevity, and user experience.

Manufacturing Process

Deep Drawing and Forming: Ensures consistent wall thickness and maintains vacuum integrity.

Precision Welding: Seals the double-wall structure without leaks.

Vacuum Evacuation: Establishes the insulating layer.

Hammered Finish Application: Uses mechanical or chemical texturing techniques for consistent results.

Polishing and Coating: Ensures a smooth, visually appealing, and hygienic surface.

Quality Assurance: Includes leak testing, thermal performance verification, and inspection of hammered finish uniformity.

The combination of engineering precision and artisanal finishing ensures that each tumbler meets high-quality standards.
