Which part of the water cup is the spin-thin process applied to?

In the previous article, the editor degraded the thinning process in detail, and also mentioned which part of the water cup is used for processing the thinning process.So is it just like the thinning process is only applied to the inner liner of the cup body, as the editor mentioned in the previous article?Answer: No.

Although most of the water cups on the market that use the thinning process are used on the inner liner of the water cup, this does not indicate that the thinning process can only be used for the inner liner of the water cup.

In addition to reducing the weight of the original product, the thinning process also partly increases the beauty of the surface of the water cup.Usually, the inner liner of the water cup that uses the thinning process is a welding process.

Many consumers and purchasers do not like this effect because there is an obvious welding scar after the finished product.The inner liner with the thinning technology will first become lighter, and it feels very obvious to get started.At the same time, as the welding scar is turned off by the rotary knife during the thinning process, the inner tank will become smooth without traces, and the aesthetics will be greatly improved.

Since the function of turning thinner is to reduce weight and remove welding scars, the shell is processed by welding process, which is also suitable for thinning process.Water cups that use spin-to-thin technology both inside and outside will become lighter.

As the wall thickness becomes thinner, the effect of vacuuming between the double layers will be more obvious on the surface, that is, the heat preservation performance of the water cup that adopts the thinning technology inside and outside will also be greatly improved.

However, there is a limit to turning thinner.Whether 304 stainless steel or 316 stainless steel, the wall thickness tolerance is limited.If the thickness of the cup wall is too thin, not only the original function of the cup cannot be maintained.In addition, because the wall of the cup is too thin to withstand the external pressure caused by the sandwich vacuum, the cup is deformed.
