How To Distinguish A Stainless Steel Vacuum Cup?

We all know that the performance of a product is closely related to its raw materials and manufacturing process.

The heat preservation effect of stainless steel vacuum thermos cup is good, also apply this truth.

Qualified stainless steel vacuum thermos cup needs to meet the standard, 95 degrees above water poured into the cup after 6 hours, the water temperature can maintain above 65 degrees.

And 3 do not have manufacturer inferior product is cannot achieve this standard.How can we tell the difference between a thermos and a thermos?

Materials - there are many different types of stainless steel, while the standard stainless steel vacuum cup USES 304 stainless steel.

This material has excellent corrosion resistance and higher price.

And inferior quality goods USES 201 stainless steel more, this kind of steel besides the price is cheap, other respect does not reach the standard of food grade use material.

The stainless steel vacuum thermos cup made of 201 is also poor in thermal insulation.

Technology - stainless steel vacuum cup can have such good insulation effect, because the design of vacuum pumping, blocking heat transfer.

And the biggest technical problem with the thermos is vacuuming.

Three manufacturers basically do not reach tailless vacuum technology, the use of a tail vacuum, vacuum cup with a pointed tail.

And the tailless vacuum process is special, and will not destroy the cup and the gallbladder because of the suction tail, so the insulation performance is even better.

Tightness - tightness is also a reflection of the cup process and performance.Add water to the thermos cup, change the lid and place it upside down to see if there is any overflow.

If no overflow occurs, it indicates good sealing performance and the insulation is guaranteed, which is conducive to carry-on.If there is any overflow, 

it means that the sealing is not up to standard. Such products not only do not have poor insulation, but also leak.

Thermal insulation - the stainless steel vacuum thermos is designed with two layers of vacuum.

If the hot water is poured into the thermos cup for 2 or 3 minutes and the surface of the thermos cup is touched by hand with obvious thermal sensation, 

then the structure design of this thermos cup cannot reach the ability of thermal insulation.

Accessories - stainless steel vacuum thermos cups are generally not cheap, not only because they have excellent raw materials and exquisite craftsmanship, 

but also because they take details very seriously.

Excellent stainless steel vacuum cup products will be carefully designed for the lid, gasket, mouth and other details to give customers a better experience.

Attention to detail of the product, its performance must not be poor.

Appearance -- from the appearance of the product, excellent products will not be left with defects, any parts of the work is very fine, 

with sophisticated materials, the cup body design is full of streamlines.

Inferior products do not pay attention to this, they rough imitation of the appearance of other products, but the use of materials and process details can be seen at a glance.

Conclusion: Many friends think it is difficult to choose a stainless steel vacuum thermos cup, no difference can be seen from the appearance, performance is good or bad only after use.

But the thing is not so complex actually, with above introduce a few methods to be able to distinguish good and bad, must not buy an inferior quality to go home to regret.
