Application of Laser Welding Machine on Metal Insulation Cup


The thermos cup is a commonly used household item, whether it is home or traveling, it is essential, especially for families with babies or cold winters. A cup of warm water warms the whole body.
The stainless steel vacuum flask is made of double-layer stainless steel inside and outside. The inner liner and the outer shell are combined by welding technology, and then the air in the interlayer between the inner liner and the outer shell is drawn out through the vacuum technology to achieve the effect of vacuum insulation. To ensure that residents have a good experience.

Generally speaking, the thinner the cup body material, the longer the heat preservation time, but the welded joint is not strong, the cup body is easily damaged and deformed, which affects the service life; therefore, it is recommended to coat the thickness of the inner container with a metal film and copper plating. Weld metal materials that are not easily damaged! In this way, the welded joint is dense, high in strength, and achieves absolute tightness.
