Explore our leading commercial-grade insulated drinkware lines engineered for global retail markets, corporate customization programs, and high-performance applications.
Leveraging 18 years of professional kitchenware development in Yongkang—the Hardware Capital of China—to deliver unrivaled efficiency and industrial capability.
Established in the heart of Yongkang's hardware cluster—a district accounting for over 90% of China's total cup and bottle production capacity—we have constructed an integrated supply chain powerhouse. By grouping raw material sourcing, mold fabrication, and surface treatments within close proximity, our facility has achieved high manufacturing agility.
Following a major industrial expansion in 2017 to an 80,000 square meter factory base, we have deployed 20 advanced production lines. These assets feature 7 dedicated stainless steel hydroforming and automated transfer lines alongside a proprietary electroplating facility, keeping quality control strictly under our own engineers.
Egg tumblers (commonly referred to as egg-shaped travel cups, wine tumblers, or double-walled vacuum insulated cups) have undergone a significant design transformation over the last decade. Originally conceived as modern thermal wine glasses, their ergonomic contours, stability, and superior insulation have made them popular for various cold and hot beverages. Today, they are widely used in offices, cafes, camping sites, and homes.
For international commercial buyers, brand managers, and procurement officers, selecting the right manufacturing partner for egg tumblers requires a deep understanding of structural materials, thermal dynamics, and consumer preferences. The demand for eco-friendly, durable, and aesthetically versatile drinkware has led to a major shift toward high-grade stainless steel products. As a result, the market has moved away from cheap, single-use plastics and single-walled glass containers.
"The modern egg tumbler has become a key item for global brand promotions, lifestyle retail lines, and outdoor collections. Its signature shape is not just aesthetic—it offers superior thermal stability and comfort compared to traditional cylindrical designs."
Innovation is central to our production philosophy. With four dedicated R&D and design centers established in Shanghai and Yongkang, we have built a robust intellectual property portfolio that includes over 110 active patents.
To stay ahead of global consumer trends, we are establishing CMF (Color, Material, Finish) production centers in China, South Korea, and Malaysia by 2025. This allows us to offer customized finishes, textures, and color options that align with current aesthetic preferences across different markets.
Our current catalog features over 120 standardized drinkware solutions, including vacuum thermoses, travel mugs, food jars, and sport flasks. Our design engineering team introduces an average of 30 new products annually, helping B2B clients keep their product lines fresh and competitive.
By 2025, our factory automation rate is projected to hit 56%, utilizing advanced robotics for welding, polishing, and vacuum sealing to ensure consistent product quality.
Our 7 automated hydroforming lines allow us to shape complex, double-walled contours without compromising the structural integrity of the stainless steel.
Every single tumbler undergoes a strict 100% thermal inspection utilizing computerized sensors to verify vacuum retention before surface finishing.
