  • How Are Stainless Steel Water Bottles Made??

    1. Manufacturing Outer & Inner Bottle

    ①Pipe Cutting: Cut stainless steel tube to the appropriate length./ Stretch: Stretch the stainless steel sheet to the appropriate length.(seamless process)

    ②Water Expansion: Place the stainless steel tube on the water expander. The pipe expands into a bottle under enormous pressure.

    ③Separating: Cuts off the two shells after water expansion with the instrument cart.

    ④Positioning & Shaping: Uses a large press, you can get the outer bottle you want, and ensure that the size of the product meets the requirements of the process drawings, and there should be no obvious defects such as wire drawing or cracking in the mouth.

    ⑤Necking: Uses a machine to squeeze the upside of the bottle to be a bottleneck.

    ⑥Thread Rolling: Threads are made with a special threading machine. Adjust the thread depth to meet the size requirements.

    ⑦Flat Mouth & Bottom: Cuts the excess part of the mouth and bottom.

    ⑧Ultrasonic Cleaning: Removes lubricating oil and dust during molding.

    2. Assembly Bottle & Bottom

    ①Assemble the inner bottle and the outer bottle together by pressing the machine.

    ②Assemble the round bottom to the bottle by pressing the machine.

    ③Weld the outer bottle and the bottle bottom to prepare for vacuum insulation.

    3. Water Leakage Test

    Check whether the welding of the inner and outer bottles is in good condition, and eliminate the unqualified products.

    4. Vacuuming

    Using the tailless vacuum technology of the machine, the vacuuming standard shall be strictly followed. A vacuum is formed between the inner tank and the outer bottle, thereby preventing heat transfer, providing insulation, and preventing hot hands.

    5. Chemical polishing

    Remove the dirt on the inner wall of the thermos bottle, and form a layer of electrolytic layer on the inner wall of stainless steel, so that the inner wall becomes more bright, not easy to attach dirt and easy to clean.

    6. Mechanical Polishing

    Polish the surface of the outer bottle to ensure that the mouth of the bottle is smooth and shiny. There must be no obvious wire drawing, scratching, black wire, and pits.

    7. External Coating

    The bottle is now ready for external coating – powder coating or spray painting or electroplate. Yihai is capable of doing both spray painting and powder coating processes. Controlled suppliers can make the perfect plating surface.

    8. Pattern And Logo Printing

    Print the pattern design and logo on the bottle with various techniques – screen printing, thermal transfer printing, water transfer printing, laser etching, 3D UV printing and so on.

    9. Packing

    After inspecting each bottle, including visual inspection and lid leak test, the bottle is placed in a separate bag for packaging.

  • What Is An Insulated Water Bottle?

    Vacuum insulated water bottle is generally a water container made of ceramic or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of water and other liquids installed inside to achieve the purpose of heat preservation. The insulated water bottle is developed from the thermos kettle. The principle of heat preservation is the same as that of the thermos kettle, but people make the bottle into a water bottle for convenience. And the water bottle is strong and durable and easy to carry.

  • How Does Insulated Water Bottles Work?

    The reason why the thermos tumbler can keep warm is mainly that the heat transfer is blocked after vacuuming. There are three ways of heat transfer: convection, conduction, and radiation, so even in a vacuum environment, heat can be transferred, but at a slower rate.

    The function of vacuuming can only block heat conduction as much as possible, but in fact, heat conduction will still occur. When the temperature of the water in the thermos water bottle is higher than the outside temperature, it can slow down the decline of the water temperature. When the temperature is lower than the outside temperature, the rising speed of the water temperature in the bottle can be slowed down. Therefore, the vacuum insulated water bottle can keep both hot and cold.

  • Where And What Can a Water Bottle Be Used For?

    The stainless steel Vacuum insulated water bottle not only be used to drink water or beverages while at home, exercising, Cycling, climbing, GMY, traveling, partying, driving, but they are also the perfect gift for personal or business events.

  • What Is The Best Insulated Water Bottle?

    Insulated bottles are made of stainless steel material, and understanding the difference between stainless steel materials will help you choose a better water bottle. There are more than 150 types of stainless steel, each with different properties. According to NSF international standards, the stainless steel used in food equipment must be either 200, or 300 series.

    ①200 series

    200 series stainless steel, such as 201 SS and 202 SS, although this series is also considered food-grade stainless steel, is more prone to corrosion or rust due to its high manganese content and very low nickel content. Therefore, it is typically used for industrial products and cannot be used for drinkware. Stainless steel in the 200 series is lower quality and less corrosion-resistant than other types. It used for the outer wall of insulated water bottle thanks to its affordability.

    ②300 series

    304 SS and 316 SS are austenitic stainless steel. Austenitic stainless steel has a low migration rate of harmful substances to food, can resist the corrosion of various media, and has high sanitary performance and processing performance. Stainless steel products related to “food” must use 304 and 316 stainless steel. 316 stainless steel is rarer than 304 stainless steel. This is an expensive, high-end stainless steel. It is mainly used in high-end equipment, such as aerospace, food machinery, and other fields. The common food-grade stainless steel used in daily life is 304 stainless steel (also known as 18/8), which has good acid and alkali resistance and strong corrosion resistance.

    Overall, high-quality 304 SS and 316 SS are better choices when choosing a food-grade stainless steel water bottle compared to other materials. As a professional stainless steel water bottle manufacturer, our wholesale insulated water bottle is made of 304/316/201 stainless steel.
