There is a limit on the diameter ratio in the production of plastic water cups. Is there such a limit in the production of stainless steel water cups?

In the previous article, I wrote in detail about the limitation of the diameter ratio of plastic water cups.That is to say, the ratio of the maximum diameter of the plastic water cup divided by the minimum diameter cannot exceed a limit value.This is because of the production limitation of the plastic water cup blowing process.So is there a limit to the diameter ratio when producing stainless steel water cups?

Before understanding the limit of the diameter ratio, the editor will briefly talk about the difference between the production process of plastic water cups and stainless steel water cups.The production of plastic water cups requires that the product be completely molded at one time, even if the blowing process uses a two-step or three-step method to the last step, the product must be molded at one time.Plastic water cups cannot be welded on the bottle body, because the pressure resistance and sealing waterability of the welded plastic bottle body will become worse.

Due to the characteristics of the material and the difficulty of production, the stainless steel water cup cannot be formed at one time.At the same time, because stainless steel is a metal, laser welding and other processes can be used, and the welded stainless steel will not affect the water sealing effect due to welding and will not cause the strength of the water cup to deteriorate due to welding.

It is precisely because the plastic water cup needs to complete the last step at one time, once the diameter ratio exceeds the limit value, the light water cup will be severely deformed, and the serious thing is that it cannot be produced and cannot be demolded.

Since the stainless steel water cup can be welded in one part or multiple parts, the limitation of the diameter ratio can be ignored.Even if the inner tank is directly large and the diameter of the cup mouth is small, the inner tank and the cup mouth of the water cup can be made separately and welded together by welding.

So when you shop daily, you will find that the cup shape changes the most and the biggest is the stainless steel water cup.On the contrary, the cup shape of the plastic water cup is relatively small, and the change is not very large.
