Explore our flagship OEM/ODM insulated drinkware collection engineered for maximum thermal retention, structural durability, and high-margin retail market penetration.
The global hydration container industry is undergoing a paradigm shift driven by stringent sustainability mandates, heightened consumer health awareness, and dynamic outdoor lifestyle trends. Within the reusable drinkware spectrum, the 500ml water bottle (17 fl oz) represents the universal "golden standard" capacity. It strikes the optimal balance between ergonomic portability, volumetric sufficiency for daily hydration cycles, and dimensional compatibility with standard automotive cup holders, backpack side pockets, and bicycle bottle cages.
Corporate brands, private-label retail sellers on platforms like Amazon, and global sports gear distributors face rising demand for food-grade, highly insulated vessels. Single-use plastic bans across North America, the EU (Directive 2019/904), and Asia-Pacific have accelerated the conversion to reusable 18/8 (SUS304) and 316 stainless steel vacuum bottles. As a premier manufacturer located in the hardware manufacturing hub of Wuyi, Zhejiang, China, Wuyi Dongyi Dailysupplies Co., Ltd operates at the nexus of material engineering and automated mass manufacturing to fulfill this international demand.
Achieving world-class cost efficiency, structural tolerance precision, and scalable OEM output requires more than basic assembly lines. The Wuyi, Zhejiang industrial hardware cluster represents the world's most concentrated, highly integrated supply chain for stainless steel vacuum insulation products.
Within a 15-kilometer radius in Wuyi, raw material processing for food-grade AISI 304/316 steel coils, precision tube-drawing mills, plastic injection lid workshops, and surface treatment specialists (electro-plating, powder coating) operate in complete sync. This minimizes raw material transit time and logistics friction.
Our factory utilizes automated multi-station hydraulic deep-drawing machines, laser seam welding, continuous vacuum degassing furnaces operating above 1050°C, and fully automated robotic electrostatic powder coating lines. This guarantees micro-inch dimensional accuracy and batch-to-batch repeatability.
High daily throughput reduces per-unit fixed overhead costs. We pass these savings directly to B2B buyers, importers, and brand owners, delivering premium thermal performance and build quality at factory-direct wholesale unit prices.
A premium 500ml water bottle must be built to withstand thermal stress, physical impact, and chemical corrosion from acidic beverages. Below is the structural decomposition of our high-performance double-wall vacuum insulated bottles:
| Component Parameter | Material Specification | Engineering Benefit & Quality Standard |
|---|---|---|
| Inner Liner (In-Contact) | Food Grade AISI 304 (18/8) or 316 Stainless Steel | 100% Rust proof, zero metallic taste transfer, resistant to fruit acids and carbonation; meets FDA & LFGB standards. |
| Outer Shell Structure | Heavy-Gauge 304 Stainless Steel | High impact strength; protects internal vacuum gap against structural collapse upon drops or impact. |
| Vacuum Layer Insulation | High-Vacuum Gap (<10-3 Pa) + Copper Plating | Radiant thermal transfer is reflected by inner copper plating. Keeps liquids cold up to 24 hours or hot for 12 hours. |
| Lid Assembly & Seals | BPA-Free Polypropylene (PP) + Food-Grade Silicone | 360-Degree leak-proof seal under high temperature and mechanical vibration; non-toxic and wear resistant. |
| Surface Finish Options | Powder Coating, Metallic Paint, UV 3D Printing, Rubberizing | Scratch resistant, anti-slip texture, sweat-proof exterior prevents condensation, highly customizable branding. |
Heat transfer occurs through three physical mechanisms: conduction, convection, and radiation. Our double-walled 500ml manufacturing process evacuates air between the inner and outer metal shells to create a high vacuum, effectively eliminating conduction and convection. Additionally, applying a micro-thin layer of copper electroplating to the exterior of the inner liner reflects infrared thermal radiation back into the bottle, locking in liquid temperatures over extended durations.
The versatile 500ml (17oz) form factor adapts seamlessly to diverse commercial and consumer end-use environments:
Fortune 500 enterprises, tech firms, and educational institutions require high-end co-branded promotional gifts. A custom laser-engraved 500ml stainless steel bottle with matte powder coating serves as an eco-friendly corporate gift that elevates brand equity.
Hikers, cyclists, and fitness enthusiasts demand lightweight yet drop-resistant hydration equipment. Our 500ml sports series with straw lids, wide-mouth openings for ice cubes, and carabiner loops fulfills rigorous field requirements.
Designed for daily commuters, urban professionals, and students. Compact bottle geometries fit neatly inside work bags, car cup holders, and desk setups without sweating or leaking onto documents and electronics.
Fast-moving direct-to-consumer (D2C) brands require rapid prototyping, custom color matching (Pantone system), unique gift box packaging, and FBA-compliant barcode labeling.
At Wuyi Dongyi Dailysupplies Co., Ltd, we transform brand concepts into market-ready retail products through a structured 6-step manufacturing workflow:
Located in Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd is a specialized high-tech manufacturer focused on research, development, and mass production of premium food-grade stainless steel tumblers, travel mugs, vacuum bottles, and beverage containers.
Operating under strict quality management principles ("Quality First, Service First"), our factory houses precision automated machinery, high-vacuum test equipment, and a dedicated engineering team. We support OEM/ODM projects across North America, Europe, South America, the Middle East, and Southeast Asia.
Our factory exports millions of vacuum-insulated units worldwide every year, supplying global brands with trusted quality, compliance, and design innovation.
As consumer preferences evolve, water bottle design is expanding beyond basic insulation into smart technology integration and eco-engineered circular materials:
Integration of UV-C LED purification caps that neutralize 99.99% of bio-contaminants inside the bottle, paired with real-time temperature displays and hydration reminders.
Advancements in necking and metal thinning technology allow outer steel walls to drop to 0.4mm without sacrificing structural durability, reducing total bottle weight by up to 25%.
Incorporating Post-Consumer Recycled (PCR) stainless steel and bio-based Tritan plastics to minimize carbon footprint and fulfill ESG requirements for corporate clients.
