What is the difference between tailless vacuum insulated cups and tailless vacuum insulated cups?

What is the difference between a vacuum insulated cup with a tail and a vacuum insulated cup without a tail? What is a tailless vacuum insulated cup? First, let's understand the structure of traditional insulated cups. Traditional insulated cups are generally made of two layers of glass or stainless steel material, with a vacuum drawn in the middle to isolate and transfer heat. Therefore, the bottom of the cup liner has a suction tail, which is easily damaged or leaked. Therefore, tailless vacuum technology was born, which is welded using special processes, so there is no need for tailless vacuum technology
There is a pointed exhaust tail, which avoids damaging the cup liner or affecting the effectiveness of the thermos cup due to air leakage caused by the exhaust tail collision.
With the innovation of thermos cup products and technology by thermos cup enterprises, a special manufacturing process called tailless vacuum technology has been born, which can avoid damage and leakage of the thermos cup liner.
Tailed vacuum is a traditional process technology, while tailless vacuum is currently one of the most advanced process technologies at home and abroad. The difference between stainless steel vacuum insulated cups produced by tailless vacuum technology and those with tails is mainly reflected in the following points:
1. Different technologies: "Tail vacuum" or "tube vacuum" is a traditional vacuum process that uses "sealing technology". This technical measure cannot completely guarantee airtightness at the microscopic level; Tailless vacuum "is the most advanced vacuum technology at home and abroad, which means that the insulation cup is controlled by a computer to complete the process of pumping, sealing, and cooling in a vacuum environment. The" fusion sealing technology "is used to ensure long-term air tightness.
2. Different equipment: The equipment for "tailless vacuum" insulated cups is a large-scale equipment with high automation and product quality, so the cost is also expensive. Moreover, the management and use technology are complex and difficult to master. The electricity consumption of a single product is several times higher than that of "tailless vacuum". Therefore, currently only a few domestic enterprises fully master and use this technology. But this process technology has high product quality and better performance, and it will inevitably become the mainstream vacuum technology in the insulation cup manufacturing industry.
3. Higher vacuum degree and longer holding time: Due to the fact that the tailless vacuum insulation cup is vacuum sealed and welded at nearly 1000 ℃, its vacuum degree is the same as that of the tailless vacuum. When the product returns to room temperature, its vacuum degree is much higher than that of the "tailless vacuum".
4. Large effective capacity: Due to the absence of a "tail vacuum" like a mouse tail, there is no need to set up a "tail hiding chamber", resulting in a large effective space. Compared with products with the same appearance volume as "tail vacuum", the effective space inside the tailless vacuum insulated cup is much larger.
