What is the function of vacuuming in the production process of stainless steel water cups?
When everyone buys stainless steel vacuum flasks, they especially shop online. When you search for a vacuum flask, you will also see the keyword "vacuum". What is the process of "vacuum"? What is the function of "vacuuming"?
"Vacuuming" is a process completed by a vacuum furnace and a getter. The purpose of "vacuuming" is to remove the air in the sandwich of the stainless steel double-layer water cup. The complete process includes two parts: exhaust and back cover. After exhausting, the double-layer room reaches the vacuum effect and then is sealed, so that the interlayer of the water cup can be kept in a vacuum state for a long time.
The function of "vacuuming" is to block the conduction of temperature, so that the water cup has a higher heat preservation effect. "Vacuuming" is also the most important process for whether the water cup can be kept warm and the length of the heat preservation time.
The better the vacuum effect, the better the heat preservation performance of the double-layer stainless steel water cup.
By controlling the length of the vacuuming time, the temperature, and the pressure, the heat preservation effect of the water cup, that is, the heat preservation time of the water cup, can be controlled.
There are some other auxiliary processes to increase the holding time of the water cup, but "vacuuming" is the prerequisite. Without the vacuuming process, any auxiliary process cannot make the stainless steel water cup have a good heat preservation effect.
The thermos cup produced by Dongguan Zhanyi Commodity Technology Co., Ltd. uses sufficient materials and exquisite workmanship. In terms of material, we insist on using food-grade 304 stainless steel inside and outside, or a combination of 304 stainless steel outside and 316 stainless steel. The heat preservation time can reach 8 hours, and the cold preservation time can reach 12 hours.
We insist on using the AQL1.0 inspection standard, which is far higher than the peer standards, and all links adopt a full inspection system to ensure that each product is a high-quality product. Customers from all over the world are welcome to visit our factory for inspection, and welcome to place orders for cooperation.
