Explore our highly requested commercial double-wall insulated designs, built for global market customization.
In the global beverage container sector, the 12oz (approx. 355ml) capacity has emerged as the definitive standard for corporate coffee programs, outdoor active hydration, and localized lifestyle accessories. The integration of high-performance double-wall vacuum insulation with customizable color, material, and finish (CMF) processes has transformed simple drinkware into essential brand statements and functional everyday tools.
For B2B buyers, distributors, and global brands, finding an authoritative manufacturing partner in China means securing a reliable supply chain that balances volume efficiency with strict safety standards. Standardized production lines now leverage SUS304 food-grade stainless steel, copper-lined thermal barriers, and advanced robotic welding techniques. This ensures products exceed consumer expectations while adhering to modern ESG directives, including recycled post-consumer metals and lead-free manufacturing steps.
Supply Chain Resilience: By consolidating components, raw steel sourcing, and finishing processes in specialized clusters like Yongkang, manufacturers can mitigate price swings, protect supply lines, and scale output rapidly to match peak global demands.
Operating from Yongkang, the core of China's drinkware export market, our production capabilities provide unique economies of scale.
18 Years of Professional Development: Our business models focus on advanced R&D and kitchenware production. By centering operations within Yongkang's hardware cluster—which accounts for nearly 90% of national cup exports—we benefit from a complete upstream and downstream network. This translates to lower shipping costs, faster prototyping, and immediate access to premium steel alloys.
Scaled Manufacturing Base: Expanding to a modern 80,000 square meter layout in 2017, the facility operates 20 active production lines. This includes seven automated stainless steel hydroforming lines, advanced laser welding centers, and an in-house eco-electroplating plant. These internal processes keep production costs stable and deliver premium finishes at scale.
Capacity Dynamics & Sales Performance: Moving into 2024 and 2025, our annual production capacity is set to cross 20 million units, with annual export sales exceeding USD 60 million. This high throughput is supported by our push toward 56% robotic automation, which improves manufacturing consistency and minimizes visual defects.
An engineering-level breakdown of the thermal performance and materials that define our 12oz tumblers.

|---|---|---|---|
| Metallurgical Composition | 18% Cr, 8% Ni (Food Grade) | 18% Cr, 10% Ni, 2% Mo (Marine Grade) | SUS316 offers superior resistance against corrosion from acidic beverages (coffee, juices). |
| Insulation Tech | Double-Wall Vacuum (10^-3 Torr) | Double-Wall + Inner Copper Coating | Copper lining reflects radiant heat, extending cold retention by 40% and heat by 30%. |
| Lead-Free Construction | Lead-Free Soldering Alloy | Lead-Free Glass Fusing Bead | Complies with Prop 65 and modern retail standards, avoiding safety liability risks. |
| Surface Finish Options | Standard Powder Coat, Spray Paint | Laser Annealing, 3D Sublimation, Soft-touch | Delivers a premium tactile experience, increases scratch resistance, and supports brand styling. |
Our 12oz double-wall insulated tumblers rely on a vacuum insulation chamber to prevent thermal transfer. By removing air between the inner and outer stainless steel walls, we eliminate conduction and convection. To minimize radiation loss, the inner stainless steel wall is coated with a thin layer of copper, which reflects infrared heat back into the beverage. This design keeps hot drinks warm for up to 8 hours and cold beverages chilled for up to 18 hours.
Global R&D Footprint: Operating four research centers in Shanghai and Yongkang, our engineering and design teams have secured over 110 active patents. To stay ahead of shifting consumer trends, we are establishing dedicated Color, Material, and Finish (CMF) design hubs in South Korea and Malaysia. These hubs focus on eco-friendly coatings, smart temp sensors, and new lid designs.
Product Pipeline: With a catalog of over 120 unique shapes—ranging from standard travel mugs and food jars to sports bottles—our team introduces an average of 30 new products annually. This quick design cycle helps our clients stay ahead of shifting consumer tastes and seasonal promotions.
Customization Versatility: Modern retail brands require unique visual identities. We offer comprehensive OEM/ODM solutions, from customized silicone gaskets and molded handles to advanced surface decorations like 3D sublimation, heat-transfer wraps, and durable matte powder coatings.
From initial concept and engineering CAD drawings to automated manufacturing and final packaging, our process is built for speed and quality.

A look inside our advanced manufacturing facility, where custom drinkware is engineered and packaged at scale.
We use high-pressure liquid systems to shape our double-wall shells, avoiding the wall thinning common in traditional stamping methods. Once formed, robotic laser welding seals the seams to ensure reliable vacuum integrity before thermal testing begins.
All powder coating and spray finishes are applied in closed, pressurized spray rooms to prevent dust contamination. The coatings are cured in high-temperature ovens to ensure durable bonding that resists chipping and scratches during daily use.
We tailor our manufacturing and logistics to meet the unique regulatory and operational needs of regional importers.
