Our 6-Step Precision Manufacturing Process

At the Eastegg 350ML Stainless Steel Mug Factory, every product undergoes a meticulous, multi-stage process to ensure superior performance and aesthetics.

Step 1: Material Sourcing & Inspection
We begin with premium 18/8 (304) food-grade stainless steel. Every sheet is inspected for grade and finish to ensure it meets our strict standards for rust resistance and durability.

Step 2: Precision Stamping & Deep Drawing
Using high-tonnage presses, the stainless steel sheets are precision-stamped and deep-drawn into the iconic mug shape. This process ensures uniform wall thickness and a robust structure for the 350ml stainless steel mug body.

Step 3: Laser Welding & Seamless Finishing
The mug handle and other components are attached using laser welding technology. This creates a strong, clean joint that is smooth to the touch and virtually invisible, a hallmark of quality from a professional stainless steel mug factory.

Step 4: High-Temperature Vacuum Insulation
The inner and outer walls are fused under a high-temperature vacuum environment. This critical step removes air to create a vacuum layer, which is the core technology that enables the mug’s exceptional temperature retention for hours.

Step 5: Multi-Stage Polishing & Surface Treatment
The mugs undergo a multi-stage polishing process to achieve a smooth, lustrous finish. They are then cleaned and prepared for the application of colorful, non-toxic, and chip-resistant powder coatings.

Step 6: Final Assembly & Rigorous Quality Assurance
In the final stage, lids, gaskets, and other components are assembled. Each Eastegg 350ml mug is subjected to a final round of rigorous checks, including:

• Leakage Test: Ensuring a perfect seal.

• Temperature Test: Verifying insulation performance.

• Visual Inspection: Confirming aesthetic perfection.
