Explore our elite selection of double-wall vacuum insulated flasks, custom mugs, and eco-friendly sports bottles engineered for international distribution.
For over 18 Years of Professional Development, we have committed ourselves to the high-performance R&D and production of premium kitchenware and drinkware solutions. Centered in Yongkang, we capitalize directly on the regional industrial cluster advantages as "China's Hardware Capital"—a critical global hub that accounts for 90% of national cup production—allowing us to refine and control the entire industrial value chain.
Our commitment to scaled operations resulted in expanding to a state-of-the-art 80,000 square meter manufacturing base in 2017. The facility currently operates 20 modern production lines, which integrate seven high-precision stainless steel hydroforming lines, automated transfer lines, and a specialized, environmentally compliant electroplating facility.
Looking to the future, our annual production capacity is on track to exceed 20 million units by 2024, driving global sales past US$60 million. To maintain our competitive edge, we are consistently upgrading our facilities, aiming for a targeted automation rate of 56% by 2025.
Why global brands and distributors are pivoting to the compact 8 oz double-wall vacuum format to capture new market demographics.
The global specialty coffee industry relies on precise liquid-to-milk ratios for flat whites, cortados, and double espressos. The 8 oz tumbler is the standard size for modern coffee houses, offering an eco-friendly option that fits under commercial espresso portafilters.
Ideal for school lunches and outdoor activities, our 8 oz vessels fit comfortably in small hands. Certified BPA-free materials coupled with robust double-wall construction ensure safety and drop resistance, providing a worry-free choice for parents globally.
Compact, high-end drinkware serves as a powerful touchpoint for premium corporate gifting. Our 8 oz tumblers offer an ideal surface area for logo laser etching, high-durability powder coating, and modern silicone sleeve branding.
Our commitment to design and engineering excellence is sustained by a Global R&D Layout. Operating four specialized design centers across Shanghai and Yongkang, we have built a design portfolio securing over 110 independent utility and layout patents.
To deepen our design leadership, we are introducing regional CMF (Color, Material, Finish) development labs across China, South Korea, and Malaysia. These hubs allow us to deliver localized design variations tailored to changing consumer preferences in diverse markets.
With an active product catalog of over 120 custom-designed double-wall vessels, travel mugs, and food containers, our product development team releases an average of 30 new SKUs each year, keeping our clients' inventory aligned with global market trends.
We maintain a rigorous quality assurance framework validated by leading international bodies to ensure seamless cross-border supply chain compliance.
Our facilities are certified to meet major international trade regulations. We hold BSCI (European Union Market Access Core Certification), Sedex (Commonwealth Market Data Sharing Certification), and ISO9001 quality management standards. Furthermore, we are fully authorized by Disney for the manufacturing of licensed products, which elevates customer transaction security and order conversion rates by up to 41%.
Every batch of raw stainless steel and polymer elements undergoes rigorous testing. We maintain full compliance with the US FDA (Food Contact Standard), European LFGB (German Food and Feed Code), and guarantee 100% BPA-Free material composition. Our products consistently pass sensory and chemical migration tests, ensuring trouble-free entry into European, North American, Japanese, and South Korean retail systems.
With structured supply logistics and compliance strategies, our products are distributed in over 80 countries.
Our sales infrastructure serves leading consumer markets in Western Europe, the United States, Japan, and South Korea. By designing products that meet regional compliance standards, we help our partners navigate localized product safety testing seamlessly.

Aligning with global ESG directives, we are implementing resource-efficient upgrades across our manufacturing network.
Responding to international sustainability standards, we are transitioning to Post-Consumer Recycled (PCR) stainless steel. We aim to offer our clients options containing up to 90% recycled alloy, lowering the carbon footprint of each unit by 35%.
We are upgrading our finishing workshops to use zero-VOC, ultra-durable powders. This upgrade eliminates hazardous emissions from the finishing process and creates a more resilient exterior that resists commercial dishwasher sanitization cycles.
By 2026, we plan to implement automated optical inspection systems on our primary lines. This integration will monitor vacuum-welding and coating consistency in real time, targeting a processing defect rate of less than 0.05%.
Answers to common B2B engineering, design, and shipping inquiries for our 8 oz tumbler line.
SUS304 (containing 18% chromium and 8% nickel) offers high corrosion resistance and structural durability for standard beverage use. For highly acidic drinks, specialized infant care, or marine environments, we offer SUS316 stainless steel, which contains 2% molybdenum for enhanced pitting corrosion resistance.
Our standard production MOQ is 1,000 units per color for customized powder coating, and 3,000 units for fully custom shapes (OEM). Laser engraving and silk-screen printing on stock colors can be arranged for smaller trial runs. Custom packaging box requirements typically begin at 2,000 units.
Every single tumbler undergoes a high-temperature infrared thermal imaging test after vacuum sealing. Units that do not meet thermal retention limits are automatically filtered out. Our standard 8 oz tumbler keeps beverages cold for up to 12 hours and hot for up to 6 hours.
We provide full verification reports, including FDA, LFGB, and compliance certificates indicating BPA-free materials. Additionally, we share our BSCI audit ID and Sedex certification details to streamline customs clearance and compliance checks for retail distribution.
Our engineering team can turn your concepts into 3D CAD files within 48 hours. Once approved, we can produce CNC and 3D-printed prototypes to verify size, grip, and weight distribution before committing to steel tooling production.
