\n\t\t\t\t\t\t\tMetalworking is the first step in the molding of stainless steel vacuum bottles. The stainless steel pipe is expanded into a predetermined shape in the mold through the pressure of water. Or use the stretching machine to punch the stainless steel disc out of the required shape and length of the inner tank of the thermos bottles many times. In this production link, we use CNC machine tools to ensure that the external dimensions of each thermos cup are consistent, so as to reduce the scrap rate of products\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\n\t\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\tAs we know, the reason why the thermos water bottle can maintain the slow change of water temperature in the bottle for a long time is that there is a vacuum isolation layer between its shell and inner tank. There is no air between the inner tank and the shell of the thermos water bottle, so the water in the flask will not conduct heat and change the temperature. All this depends on the vacuum treatment process of the insulated water bottle, which is also the fundamental reason why our products sell well. Therefore, we have invested the most in quality control in this link to ensure the stability of product quality.\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\n\t\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\tThe polishing of stainless steel shell is very important for the subsequent external surface treatment of thermos water bottle. The smooth surface is conducive to the painting and pattern printing of the outer surface of the insulated water bottle. There are many styles of thermos cups in our products. The outer surface is not cylindrical, but curved. These styles of thermos bottles put forward higher requirements for the polishing process of stainless steel shell, so the employees operating this link must have more than 5 years of rich experience, which is also one of the keys for our products to be ahead of other brands.\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\n\t\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
