Core Concepts and Key Technologies

Double-Wall Vacuum Insulation

The central technology of this medium-sized beer cup is double-wall vacuum insulation, which significantly reduces heat transfer and maintains beverage temperature for extended periods.

Inner Wall: Comes into contact with the beverage, constructed of food-grade stainless steel to ensure taste neutrality and corrosion resistance.

Outer Wall: Remains cool to the touch and provides structural support.

Vacuum Layer: Eliminates conduction and convection, reducing heat or cold loss.

Hammered Exterior: Enhances grip, adds visual appeal, and reinforces structural integrity.

Thermal Performance:

Hot beverages: 1–3 hours

Cold beverages: 3–6 hours

This design ensures beverages maintain optimal temperature during office hours, commutes, outdoor picnics, or social gatherings.

Hammered Coating Exterior

The hammered exterior is more than an aesthetic feature:

Grip Enhancement: The textured surface prevents slipping, especially when condensation forms.

Durability: Protects the surface from scratches and minor dents.

Premium Appearance: Provides a tactile and visual premium feel that differentiates it from standard smooth tumblers.

Additionally, this surface allows for customization, including corporate branding, colored finishes, and promotional designs.

Product Structure, Materials, and Manufacturing

Structural Composition

The medium-sized Insulated Beer Cup includes several critical elements:

Inner Liner: SUS 304 or SUS 316 stainless steel, ensuring durability, corrosion resistance, and safety.

Outer Shell: Stainless steel with hammered coating for aesthetics and mechanical reinforcement.

Vacuum Insulation Layer: Provides thermal retention.

Base: Designed for stability on various surfaces.

Optional Lid: BPA-free, reduces spillage, and enhances temperature retention.

Material Considerations

SUS 304/316 Stainless Steel: Corrosion-resistant, durable, safe for contact with beverages.

Hammered Coating: Increases durability, grip, and aesthetic value.

BPA-Free Lids: Ensure safety during use and transport.

Manufacturing Process

Deep Drawing and Forming: Produces consistent wall thickness and a precise shape.

Seamless Welding: Ensures leak-proof construction.

Vacuum Sealing: Establishes the insulating layer for superior thermal performance.

Hammered Coating Application: Mechanically or chemically applied for uniformity.

Polishing and Finishing: Provides hygiene and aesthetic appeal.

Quality Inspection: Includes leak testing, thermal performance verification, and finish quality control.

This approach merges engineering precision with design aesthetics, producing a product suitable for both B2B and consumer markets.

Factors Influencing Quality and Performance

Thermal Retention

Key factors affecting temperature retention include:

Integrity of Vacuum Layer: Any breach reduces insulation efficiency.
