Introduction to the Thermos Flask Lid

As an important part of the thermos flask, the thermos flask lid not only serves the function of sealing and heat preservation, but also takes into account practicality and aesthetics in its design. It comes in a variety of materials, with common ones being plastic, stainless steel, etc. The plastic lid is lightweight and affordable, while the stainless steel lid is more durable and safe. The design of the thermos flask lid is also very ingenious, with various opening methods such as push - type and screw - type, meeting the usage needs of different people.

Performance of Ultrasonic Welding in the Production of Thermos Flask Lids

In the production process of thermos flask lids, one of the steps requires the use of ultrasonic welding to make the surfaces of two objects rub against each other and form a fusion between molecular layers. For thermos flask lids, this welding method can achieve efficient and precise connection, ensuring the tightness and stability of the lid. Moreover, ultrasonic welding does not generate excessive heat, which will not damage the material of the lid, thus guaranteeing the quality and safety of the lid.
