What is tailless vacuum flask technology?

One of the most important factors in the insulation effect of avacuum insulated cupis vacuuming. The stainless steel vacuum thermos cups currently sold on the market, due to different vacuuming techniques, can be roughly divided into two products with different process technologies: tubular vacuum - tailed vacuum; overall vacuuming - tailless vacuum.

The traditional thermos cup is made of two layers of stainless steel inside and outside, with a vacuum in the middle to isolate heat transfer. Therefore, there is an exhaust tail at the bottom of the cup, which is easily damaged; tailless vacuum technology is The tail port is welded with a special process, so there is no sharp exhaust tail, which prevents the exhaust tail from being damaged and damaging the cup bladder. "Tailless vacuum" is currently one of the most advanced process technologies at home and abroad. That is, the vessel is controlled by a computer to complete the process of pumping, sealing, welding, and cooling under vacuum environmental conditions.

Features of tailless vacuum technology:

1. High vacuum degree and long heat preservation time

Since it is evacuated and sealed at nearly 1000°C, if the vacuum degree is the same as that of tailed vacuum, when the product returns to normal temperature, its vacuum degree will be much higher than that of "tailed vacuum".

2. Large effective capacity

Since there is no rat tail like a "tailed vacuum", there is no need to set up a "tail hiding room", so the effective space is large. Compared with "tailed vacuum" products with the same appearance volume, "tailless vacuum" products have much larger internal effective space.

3. Long service life

"Tailed vacuum" uses "pressure sealing technology". This technical measure cannot completely guarantee airtightness from a micro perspective. The "tailless vacuum" uses "fusion sealing technology", which melts the solder at high temperature and seals the air extraction hole, so it can ensure that there is no air leakage for a long time.
