Nine Years of Coating Application
Dongke Electric Heating started in 2017. We have nine years of experience with inorganic nanocoatings for drinking containers. Our R&D team developed the coating formula and spraying process independently. We own all the intellectual property rights. We produce 10,000 cups per day. Our coating line produces zero VOC emissions. This meets global environmental standards. Leading cup brands in China have adopted our coating and use it in mass production.
Pure Coffee Taste Every Time
The All Stainless Steel Coffee Mug is designed for coffee lovers. It has a 304 stainless steel inner layer and a 201 stainless steel outer shell. The double-wall vacuum design keeps drinks hot for 6 to 12 hours. Both the inner and outer surfaces have our hydrophilic coating. Coffee contains natural oils and tannins. In regular mugs, these substances leave a brown oil film on the wall over time. This film affects the appearance and can release old flavors when you use the mug again. This may affect the taste of fresh coffee. Our coating is smooth and dense. Coffee oils have very low adhesion to the surface. When you rinse with water, the water spreads into a continuous film. It lifts the oils away from the wall. The All Stainless Steel Coffee Mug stays like new after each wash. It does not retain odors or colors.
Three Sizes for Different Needs
The coating also helps inhibit bacterial growth. This helps keep every drink clean and fresh. Capacities are available in 280 ml, 380 ml, and 480 ml. These sizes meet different drinking needs. The plastic straight-drink lid is easy to use with one hand. Colors include creamy white, pure white, sky blue, black, gray, and red. The style is modern and simple. This product was launched in spring 2026. It is suitable for coffee shop merchandise, corporate gifts, and retail sales. We offer OEM and ODM services. We support custom logos and packaging design. We provide samples before mass production. The minimum order quantity is 1,000 pieces. We offer a 12-month warranty. Repeat orders have a delivery time 5 to 10 days shorter than the first order.
