Deep Experience in Nanocoatings
Shaoxing Dongke Electric Heating Technology Co., Ltd. has nine years of experience in inorganic nanocoatings. We started in 2017. Our R&D team developed the coating formula and spraying process independently. We own the core technology. We produce 10,000 cups per day. Our coating line produces zero VOC emissions. Leading cup brands in China have approved our coating. We have established stable mass production partnerships with them.
Switch Drinks Without Old Flavors
The Spill Proof Insulated Tumbler solves a specific problem. Many people use the same cup for coffee, tea, and juice on different days. The problem is that the taste and color from the previous drink often remain in the cup. This affects the next drink. The tumbler has a 304 stainless steel inner layer and a 201 stainless steel outer shell. The double-wall vacuum design keeps drinks hot or cold for 6 to 12 hours. Both surfaces have our hydrophilic coating. The coating has almost no pores. Drink pigments and flavor molecules cannot easily attach to it. They have little space to adhere. When you rinse with water, the water spreads into a continuous film. It lifts the residue from the microscopic surface. After one rinse, the Spill Proof Insulated Tumbler leaves almost no trace of the previous drink. You can switch to a different drink without flavor mixing.
American Style with Smart Options
The coating also helps inhibit bacterial growth. Capacities are available in 380 ml and 510 ml. The PP screw lid provides a secure seal. The design follows an American style. We offer two series. One features a textured surface. The other comes with a leather sleeve. Each series is available in five colors: black, white, green, blue, and pink. We also offer a version with a temperature display. This product was launched in 2026. It is suitable for commuting, sports, and outdoor activities. We offer OEM and ODM services. We support logo engraving and packaging customization. We provide samples before mass production. The minimum order quantity is 1,000 pieces. We follow AQL inspection standards for quality control. We offer a 12-month warranty.
