In a previous article, I wrote in detail about the restrictions on the diameter ratio during the production 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 limitations of the plastic water cup blowing process. of. So are there any restrictions on the diameter ratio when producing stainless steel water cups?
Before understanding the limitations of the diameter ratio, we need to briefly talk about the difference in the production process of plastic water cups and stainless steel water cups. The production of plastic water cups requires that the product be completely formed in one step. Even if the bottle blowing process uses a two-step or three-step method, the product must be formed in one step until the last step. Plastic water cups cannot have bottle welding, because the pressure resistance and water sealing properties of the welded plastic bottle will deteriorate.
Due to the characteristics of the material and the difficulty of production, the product cannot be formed in one go. At the same time, because stainless steel is metal, laser welding and other processes can be used. The welded stainless steel will not affect the water sealing effect due to welding, nor will the water cup be damaged due to welding. Strength deteriorates.
It is precisely because the plastic water cup needs to complete the last step at once. Once the diameter ratio exceeds the limit value, the light cup will be severely deformed, and the heavy cup will simply not be able to be produced and cannot be demoulded.
Stainless steel water cups can be welded in one or multiple parts, so the limitation of diameter ratio can be ignored. Even if the inner tank is very large and the diameter of the cup opening is very small, the inner tank can be separated from the mouth of the water cup. Made by welding.
