However, the welding of the cup body and the cup bottom requires high flatness and smoothness of the welding position. Otherwise, the welding quality will be affected, and invisible air leakage will occur after vacuuming. The thermos cup will not be able to keep warm for a short time, especially when unqualified thermos cups are repaired, the requirements for cutting and flattening the cup bottom are more stringent.
