Engineered to exceed FDA, LFGB, and BS EN 12546-1:2000 thermal regulations.
Within the commercial kitchenware and outdoor lifestyle sectors, enterprise buyers increasingly require multi-functional drinking solutions that satisfy the requirements of remote travel, industrial worksites, and collaborative settings. The "Flask 3 Cup" configuration represents a milestone of structural design—integrating a core double-walled, high-volume insulated body with a nested system of three interlocking premium steel or polymer serving cups.
By offering a modular, shared beverage experience, this design effectively eliminates the requirement for transport parties to pack redundant cup units, optimize packaging efficiency, and minimize physical footprint during field service operations. Global retail chains, promotional agencies, and industrial supply businesses depend on manufacturers who can deliver these thermal solutions at scale, maintaining material purity, thermal efficiency, and design refinement across production batches.
Our manufacturing foundation is built on 18 years of specialized product development in kitchenware and high-performance drinkware. Strategically situated in Yongkang—recognized globally as "China's Hardware Capital"—our operation draws directly from a supply cluster that generates over 90% of the global cup production. This geographical advantage enables us to integrate the entire production cycle, from raw sheet metal procurement to complex surface treatment processes.
Expanding our footprint in 2017 to an 80,000 square meter facility, we have deployed 20 modern automated production lines. These lines include 7 stainless steel hydroforming and automated material transfer stations, as well as a dedicated, fully-compliant electroplating facility. By 2024, our annual manufacturing capacity will exceed 20 million units, representing global sales of over $60 million USD. Our capital reinvestment plan ensures that our factory automation index will rise to 56% by 2025, reducing cycle times and optimizing dimensional tolerances.

Enterprise buyers do not simply buy cups; they build reliable consumer ecosystems. We align our manufacturing capabilities with the specific supply requirements of regional buyers.
Leveraging our upcoming CMF (Color, Material, Finish) production centers in China, South Korea, and Malaysia, we offer advanced PVD coating, water transfer printing, and high-precision laser marking to ensure brand integrity.
We mitigate international logistic risks through advanced supply forecasting and flexible raw material inventories of SUS 304 and SUS 316 stainless steel, maintaining stable lead times even during seasonal peaks.
Our products comply with strict international requirements, including FDA, LFGB, and BPA-free standards. Our sensory and chemical migration tests ensure smooth customs clearances in Europe, North America, and Japan.
With four specialized R&D centers established across Shanghai and Yongkang, our engineering teams have filed more than 110 product design and utility patents. Our product iteration cycle is among the fastest in the industry, supported by a portfolio of over 120 products in the vacuumware sector. On average, we introduce 30 new products annually to keep pace with changing consumer demands.
From a metallurgical perspective, our Flask 3 Cup systems are engineered to withstand extreme physical stresses. We use premium grade 18/8 (SUS304) stainless steel for the inner and outer vessels, and offer optional marine-grade 18/10 (SUS316) for inner liners to handle acidic beverages. Our vacuum chambers undergo high-temperature outgassing at 1000°C to create a 10^-5 Pa vacuum layer, coupled with inner-wall copper coating to minimize radiative heat transfer.
Our OEM/ODM pipeline transforms concepts into market-ready retail products through six structured development stages.
Brand partners share initial design concepts, hand sketches, or target product photos outlining their performance criteria.
Engineering develops structural CAD drafts and 3D mockups, detailing wall thicknesses and nesting cup threads.
We generate 3D resin models and initial steel prototypes to evaluate hand feel, structural integrity, and cup nesting performance.
We manufacture custom injection and hydroforming molds within our facility to guarantee highly consistent physical dimensions.
We apply high-durability surface coatings, such as powder coat, electroplating, and custom artwork, using laser engraving.
Completed production batches undergo vacuum decay, leak-proof testing, packaging assembly, and global freight dispatch.
Our manufacturing facility holds key compliance certifications to facilitate import operations for global brands. We maintain active compliance systems, including BSCI (Business Social Compliance Initiative), Sedex (SMETA audit system), and ISO9001 quality management standards.
Furthermore, we are fully authorized for production under the Disney FAMA licensing framework, an audit level that increases order acquisition success rates for major accounts by 41%. On a product safety level, every batch is certified to satisfy FDA, LFGB, and BPA-Free regulatory guidelines.
