At the same time, due to the problem of vacuum pressure, square stainless steel lunch boxes need stronger tensile strength to avoid vacuum deformation as much as possible. This also requires the thickness of the material. Of course, the thicker the material, the lower the tensile

In the previous article, we briefly communicated with you the difficulty of producing stainless steel square vacuum lunch boxes. Today we will continue to share with you the remaining production points to pay attention to.

Can all square double-layer stainless steel vacuum-insulated square boxes be mass-produced?

At the same time, due to the issue of vacuum pressure, square stainless steel lunch boxes need stronger tensile strength to avoid vacuum deformation. This also requires the thickness of the material. Of course, the thicker the material, the better the tensile resistance. The stronger it is, but in terms of people’s usage habits and feel, the lunch box should not be too heavy, and the material should not be excessively thickened due to tensile strength. If it is too heavy, it will cause instability in people’s use. After many tests by us, We find a relatively optimal material thickness index. I don’t need to explain this in detail. Friends in the industry believe that with the editor’s words, they can basically predict the thickness of the material through simple judgment.

The key is here. This step is the most critical step in the final successful production of square stainless steel insulated square boxes. Due to their shape, square lunch boxes are easily deformed during vacuuming, so how to keep them from deforming? Why doesn’t the cylindrical lunch box deform? Is there any way to compromise? Okay, the editor has revealed very important information. Friends who can understand it believe that they already know how to do it. #Lunch box# #Insulated lunch box# #Stainless steel lunch box# #Square lunch box# #Experience sharing#

Okay, after talking so much, I have to retain some techniques. and production requirements, so that we can more respect the hard work of technical personnel. Friends who are in the same industry and understand must know that this article is based on words rather than facts.
