The difference between a sealed and seamless inner liner of a thermos cup

1. Process difference: Welding vs. Integrated Forming (1) Seam inner liner: It is formed by welding metal sheets after curling, and the seams are usually laser or high-frequency welded. The advantage is that the production cost is low (about 30% lower than seamless inner liner), but the weld seam is prone to residual metal shavings […]
Reasons for the heating of the thermos cup lid and whether it affects the insulation effect

The heating of the thermos lid does not necessarily indicate poor insulation effect, but may be related to factors such as the sealing of the lid and the material used. 1. The reason for the heating of the thermos cup lid There may be several reasons for the heating of the thermos cup lid, including: […]
Exploring the Metal Materials Used for the Inner Wall of Insulated Bottles

1. Core structure and function of thermos bottle Insulated bottles achieve insulation function with their unique vacuum layer design, reducing heat loss during temperature transfer. In order to further enhance the insulation effect, the inner wall of the thermos bottle is usually made of a layer of metal material with superior thermal conductivity. 2. Common […]

Identification method for thermos cups

1. Identification of insulation properties of the inner liner This is the main technical indicator of a thermos cup. After filling it with boiling water, tighten the bottle stopper or lid clockwise. After 2-3 minutes, touch the outer surface and lower part of the cup body with your hand. If you find obvious warmth on […]
Insulated Cup Science Popularization – Secrets in Numbers

In daily life, almost all the thermos cups we use are labeled with numbers such as 304, 316, 18/8, but most people do not know the meaning of these numbers. 1.304, 316 304 and 316 represent different stainless steel materials. The safety of the insulated cup depends on the material of the inner liner. What […]
