Sparkling Water Tumbler

A Company Built on Coating Science

 

Shaoxing Dongke Electric Heating Technology Co., Ltd. was founded in 2017. Our company has nine years of experience with inorganic nanocoatings. Our R&D team developed the coating formula and spraying process in-house. We own the full intellectual property rights. Our factory covers 5,000 square meters. We have 180 employees. We produce 10,000 cups per day. Our coating line produces zero VOC emissions. This meets environmental standards in Europe and America. Leading drinkware brands in China have approved our coating technology and use it in mass production. Our team understands how to apply coatings that provide long-lasting performance on stainless steel surfaces.

The Sparkling water tumbler is designed for people who value quality. The body features a 304 stainless steel inner layer and a 201 stainless steel outer shell. The double-wall vacuum insulation keeps drinks hot or cold for 6 to 12 hours.

The lid is made of stainless steel, which is different from most tumblers on the market. Plastic lids may feel less premium, crack over time, and provide weaker sealing performance. Our metal lid provides a solid feel in your hand. It screws on securely and helps prevent leaks. It also offers better durability than plastic lids.

This makes the Sparkling water tumbler an excellent choice for office use and car commutes. The metal lid also helps reduce heat loss because metal provides different thermal performance compared with plastic materials.

The inner surface features our hydrophilic coating. Coffee contains natural oils that can leave a thin film inside any cup. If not cleaned promptly, these oils may oxidize and develop brown stains that are difficult to remove. They may also create unwanted aftertastes that affect the flavor of your next cup of coffee.

Our coating helps prevent this problem. The coating is smooth and dense. Coffee oils are less likely to adhere to the surface. When rinsed with water, the water spreads into a continuous film. This film helps lift oils and residue away from the inner wall. The Sparkling water tumbler can be cleaned easily with a simple rinse, helping maintain a fresh coffee taste.

The coating also helps prevent bacterial growth. This helps keep your drink cleaner. The capacity is 500ml, providing enough volume for a long morning at work or a long drive. You do not need to refill it frequently.

Colors are available in three options: double-layer natural, double-layer white, and double-layer black. The design has a sporty appearance. This product was launched in spring 2020 and has demonstrated reliable performance through years of market use.

This tumbler is suitable for office workers and gym users. It is also a good choice for corporate gifts. We offer OEM and ODM services. We support logo engraving and packaging customization. We provide samples before production. The minimum order quantity is 1,000 pieces. We provide a 12-month warranty. Repeat orders have a delivery time that is 5 to 10 days shorter.
