How to choose stainless steel insulation Cup

See the material

There are many kinds of stainless steel materials. There are 201 stainless steel, 202 stainless steel, 304 stainless steel, etc. which are often used as heat preservation cups on the market. The corrosion resistance of 304 stainless steel is better than 201 stainless steel, and the price will be more expensive. Therefore, most of the stainless steel heat preservation cups on the market are made of 304 stainless steel.

Look at technology

The most important principle of the insulating cup is to vacuumize between the two-layer stainless steel structures, because the vacuum does not transfer heat. Vacuum technology can be divided into two types: tailless vacuum and tailed vacuum. The traditional heat preservation cup will have an exhaust tail. Tailless vacuum technology is to weld the glass mouth with a special process, so there is no sharp exhaust tail to avoid damage to the cup liner due to the collision of the exhaust tail. The tailless vacuum technology is more advanced and the heat preservation effect is better.

See tightness

After adding water to the cup, turn it upside down to see if there is water overflow. If not, it indicates good sealing performance. The sealed cup will not leak.

Heat preservation performance

Put in hot boiled water, touch the surface of the insulation Cup after 2-3 minutes, if there is obvious warm phenomenon, it means that the vacuum insulation performance has been lost.

Details determine success or failure. A good insulating cup is not only technology and materials, but also requires the spirit of excellence in details.

The quality of the cup cover mat determines the tightness of the cup. The material and technology of the cup bottom mat reflect the humanistic feelings of an enterprise.
