Core Concepts and Key Technologies

Double-Wall Insulation

The core feature of the 8oz beer cup is its double-wall insulation, which minimizes heat transfer and preserves beverage temperature. Key aspects include:

Vacuum layer: Reduces conduction and convection between the inner liquid and the external environment.

Reflective stainless steel interior: Reflects thermal radiation, further enhancing retention.

Lid integration: The secure lid minimizes heat loss and prevents spills, maintaining optimal temperature longer.

Thermal performance estimates:

Cold beverages: Maintain optimal temperature for 3–5 hours

Hot beverages: Retain heat for 1.5–3 hours

These parameters ensure that beverages are served at their ideal temperature, which is crucial for quality control in commercial settings and convenience for personal use.

Lid Functionality

The lid serves multiple purposes:

Spill prevention: Reduces the likelihood of accidental spills during transportation or outdoor activities.

Temperature retention: Limits heat loss or gain by sealing the cup.

User convenience: Easy to open and close, compatible with ergonomic handling.

The combination of double-wall insulation and a well-fitted lid ensures that the cup performs efficiently in diverse environments.

Product Structure, Materials, and Manufacturing

Structural Design

The 8oz beer cup consists of several integral components:

Inner liner: Food-grade stainless steel (SUS 304 or 316) resistant to corrosion and flavor contamination.

Outer shell: Polished stainless steel providing durability and aesthetic appeal.

Vacuum cavity: Double-wall layer for thermal retention.

Base: Stable and anti-slip to prevent tipping.

Lid: Securely fits to prevent spillage and support thermal performance.

Material Selection

SUS 304/316 stainless steel: Offers corrosion resistance, maintains flavor neutrality, and ensures longevity.

Polished exterior: Enhances visual appeal and ease of cleaning.

BPA-free or food-safe silicone lid seal: Ensures safety and prevents leaks.

High-quality materials ensure durability, user safety, and hygiene, critical for wholesale and corporate buyers.

Manufacturing Process

Deep drawing and forming: Ensures uniform wall thickness, optimizing insulation.

Precision welding: Seals the vacuum cavity without compromising structural integrity.

Vacuum evacuation: Creates the insulating layer essential for double-wall performance.

Polishing and finishing: Provides a smooth surface, enhancing grip and aesthetics.

Quality assurance: Includes thermal testing, leak tests, and material certification verification.

This meticulous manufacturing process guarantees consistent quality across batches, essential for B2B and wholesale distribution.
