Is it normal to find that the newly purchased water bottle is slightly out of round?

Recently, a friend left a message to Editor, asking Editor to find that the newly purchased water cup was not round when he held it in his hand.When I touch it with my hand, it seems to be a little flat. Is it normal?

The editor first explains several possibilities that cause the cup to be out of round.The first is that the production process and process management are not rigorous enough, causing out-of-round products to flow into the market.

Secondly, due to the structure of the product itself, it cannot be completely round during production.Many water cups on the market are like this, and I will not list them one by one here.Because of the shape of some water cups, the plastic surgery process cannot be done completely, so it can only be shipped in the best possible state.

Finally, some water cups are out of round due to unreasonable handling and backlog during transportation.

Is waterbottleout-of-roundness a normal production phenomenon? In the editor's understanding, there are requirements for out of roundness, and the requirements for roundness in the production of water cups are also clearly marked, and some product errors are also allowed, so a water cup that is slightly out of round is normal.

Which are abnormal?The water cup is obviously unreasonably deformed, and some even have edges and corners caused by backlog, or pits, which are abnormal phenomena.

Will an out-of-round water bottle affect the heat preservation performance of the water bottle?Out-of-round water cups, which belong to a reasonable category in production, will not affect the thermal insulation performance of the water cup, nor will it affect the sealing performance of the water cup.

These water cups that are seriously out of round and obviously deformed may cause the water cup to no longer keep warm, and more seriously, the loss of sealing due to the deformed lid of the water cup that cannot be well matched.

Therefore, the specific out-of-roundness is analyzed in detail.If you have friends who are worried, you can contact Editor to send pictures or videos to Editor to see. Editor hopes to help everyone with my own experience.
