Yutanpo Hot water bottle making process

Creating a steel hot water bottle involves several steps and processes. Steel hot water bottles are designed to hold and release hot water for various purposes, such as providing warmth in bed or soothing muscle aches. Here's a general overview of the manufacturing process:

  1. From raw Materials:  High-quality stainless steel is the primary material used for making hot water bottles due to its durability and resistance to corrosion. The steel is typically in the form of sheets or rolls.
  2. Cutting and Shaping: The steel sheets are cut into the desired shape for the hot water bottle. This shape typically resembles a flat, rectangular bag with a neck or spout at one end.
  3. Seam Welding: The cut steel pieces are welded together along the edges to create a sealed container. This welding process ensures that the bottle is watertight and can withstand the pressure of hot water.
  4. Neck/Spout Formation: The neck or spout of the hot water bottle is formed during the shaping process. It is essential for filling and emptying the bottle.
  5. Testing and Inspection: Each bottle undergoes rigorous quality control checks to ensure that there are no leaks or defects in the welds. It is important to prevent hot water from escaping and potentially causing burns or injuries.
  6. Surface Treatment: The exterior of the hot water bottle may undergo surface treatments, such as polishing or coating, to improve its appearance and protect it from corrosion.
  7. Filling and Sealing: Hot water bottles are typically sold empty to be filled by the end-users. The user fills the bottle with hot water from a kettle or other heat source. The neck or spout is then sealed securely to prevent any water from escaping.
  8. Testing for Safety: Manufacturers often conduct safety tests, such as pressure testing, to ensure that the bottles can withstand the temperature and pressure of hot water without bursting or leaking.
