What are the inner crafts of stainless steel water cups? Can it be combined?

What are the production processes for the inner tank of stainless steel water cups?In terms of tube forming process for the inner tank of stainless steel water cup, we currently use drawn tube welding processing and stretching processing.As for the shape of the water cup, it is usually completed by the water expansion process, and the stretching process can also achieve the completion of the shape, but the relative efficiency will be lower and the cost will be higher.

I will not describe the differences and characteristics of these processes.In the previous article, the editor has made many introductions. If you need to know more about it, you can read the article published by the editor.

For the inner container of the double-layer stainless steel vacuum water cup, can these processes be combined?The answer is yes. The editor briefly discusses with you about the method of combination.Both the inner and outer tanks of the cup body can be welded by drawing tubes at the same time, or both the inner and outer tanks can be drawn by the drawing process, and the inner tank can be stretched and the outer shell can be welded by drawing tubes. These are also commonly seen in the market.

If you see here, some friends will ask, why can’t the inner bladder tube be welded and the outer shell is stretched?If a friend asks this question, it means that I have been following the editor for a very short time and did not read the previous article of the editor.

This has to be considered in terms of cost and beauty. I can’t say with certainty that there must be no such practice. I even believe that for different products and different functions and process completions.There will definitely be water cups processed in this way, but this method is indeed rarely seen in the daily production of water cups in the editor.

Generally, the purpose of combining the two processes is basically to achieve the desired effect of the customer while also reducing the production cost. So these processes can be combined.
