Can all square double-layer stainless steel vacuum insulation boxes be mass-produced? (two)

In the last article, we briefly communicated with you the production difficulty of stainless steel square vacuum lunch boxes, and today we will continue to share the remaining production points with you.

At the same time, due to the vacuum pressure problem, the square stainless steel lunch box needs stronger tensile strength, so as to avoid vacuum deformation as much as possible.Then this also requires the thickness of the material. Of course, the thicker the material, the stronger the tensile strength.However, as a lunch box for people's usage habits and feel, it should not be too heavy, and the material should not be thickened due to excessive tensile strength. If it is too heavy, it will cause people to use it unchanged.

After many tests, we found a relatively optimal material thickness guide.This is the same reason, no need for Editor to explain in depth, friends in the same industry believe that with this sentence of Editor, you can basically predict the thickness of the material through simple judgment.

The key is here. This step is the most critical step to finally realize the success of the production of square stainless steel thermal insulation boxes.Due to the shape of the square lunch box, it is easy to be deformed when it is vacuumed, so how to make it not deformed?Why is the cylindrical lunch box not deformed?Is there a way to compromise?Well, the editor has revealed very important information, and friends who can understand it believe that they already know how to do it.
