Easy Tumblers

A Brand with Deep Coating Expertise

 

Shaoxing Dongke Electric Heating Technology Co., Ltd. has spent nine years developing inorganic nanocoatings. We started in 2017. Our R&D team handles everything from molecular design to spraying. We own all the intellectual property rights. We produce 10,000 cups and 5,000 cookware pieces per day. This gives us the capacity to handle bulk orders from brands. Our coating process produces zero VOC emissions. This meets environmental standards in Europe and North America. Leading cup brands in China have tested our coating and placed mass production orders with us.

The Easy Tumblers solve a common problem in the drinkware industry. Coffee and tea leave stains on stainless steel inner walls. Traditional polishing can still leave tiny rough areas on the metal surface. Tannins and pigments from drinks can enter these areas. Over time, this causes discoloration and unpleasant odors. Our coating creates a smooth, ceramic-like layer on the metal surface. The surface has almost no pores. Stains have nowhere to attach. After daily use, you simply rinse the Easy Tumblers with water. Coffee oils and tea residue slide off easily. The inner wall stays clean and shiny like new. It does not retain colors or odors even after many months of use.

This tumbler has a 316 stainless steel inner layer and a 304 stainless steel outer shell. The double-wall vacuum design keeps drinks hot or cold for 6 to 12 hours. The capacity is 450 ml. This size fits standard car cup holders. The lid is made of PP plastic and includes a straw and temperature display. This allows you to check the drink temperature at a glance. The coating also has antibacterial properties. Tests show that it is effective against E. coli and Staphylococcus aureus. Available colors include white, white-black, white-blue, white-red, and white-coffee. The style is modern and simple. It is suitable for commuting, office use, and outdoor activities. This product was launched in summer 2026. It is our newest tumbler line. We offer OEM and ODM services. We support logo engraving, packaging design, and color customization. We provide samples before mass production. The minimum order quantity is 1,000 pieces. We offer a 12-month warranty.
