How to determine the defects of the newly purchased stainless steel thermos?

Hello everyone, "Dong Dong Talk Cup" is here. As the editor shares more and more articles about how to judge the quality of a newly purchased thermos, he has received more and more messages from friends, hoping that the editor can use an article to explain the common problems at once. The editor is willing to follow the advice. http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlToday, this article will show you which problems of the newly purchased stainless steel thermos are considered defects.

The first step is to observe the overall appearance, focusing on the defects on the cup body.

Scratches and dents: Any obvious scratches or dents in appearance are considered defects. http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlThese defects will affect the appearance of the thermos and may weaken the structural strength. Defects!

Welding marks: If the stainless steel welding is not handled properly, it will leave rough welding marks, which not only affects the appearance, http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlbut may also cause water leakage during use. Defects!

Coating peeling: If the thermos has a coating design on the outside, peeling coating is also a common defect. This is usually caused by poor production process. Defect!

Secondly, judge the cup lid, because the cup lid is an important part of the thermos cup. http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlA defective cup lid usually cannot guarantee the function of the thermos cup.

Damaged or mismatched seal: If the seal is cracked, hardened or does not fit the right size, it will cause the thermos to have a poor seal and leak easily. Defects!

Thread damage: If the lid thread is damaged, http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlit may not close tightly or cannot open and close properly. Defects!

Material cracks and plastic burrs: Especially in plastic cup lids, any cracks or breaks are obvious defects. Many consumers are not sure whether the burrs are defects when buying water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlJust remember that if you feel obvious scratches or tingling when you touch it, it is a defect!

In the previous article, the editor focused on some problems with the inner liner of the thermos bottle. Today, the editor will summarize it again.

Deformation or dents in the liner: If the liner is deformed or dented, http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlit will affect the insulation effect and may cause structural problems. Defects!

Solder point problem: If the solder points of the inner tank are not properly handled, it may affect the service life and safety. Black solder lines at the bottom, solder points and scratches on the inner wall are all considered defects!

Finally, let me talk about the noisy cup. When you shake the cup, it feels like there are metal particles in the interlayer of the cup colliding with the cup wall and making noise. http://www.zhanyict.com/en/ProductsDetail-VB-10489.htmlThe reason for this phenomenon is that the getter in the interlayer falls off. Although it often does not affect the thermal insulation performance of the cup, it is still a defective product.
