Why in the production of stainless steel water cups, some water cups can be polished, but some can only be electrolyzed?

When producing stainless steel water cups, there are many ways to treat the internal surface. These methods include polishing, electrolysis, baking ceramic paint and enamel processes, and electrolysis and polishing processes are the most used.

The internal polishing process plays a role not only to smooth the rough edges caused by the laser welding process, but also to remove some stains, oil stains and welding lines that the stainless steel water cup touches during the production process.

At the same time, such as mirror electrolysis, baking ceramic lacquer and enamel processing, the better the polishing effect, the more advantageous and better the effect can be achieved for the development of these processes. But why some stainless steel water cups can only be electrolytically treated but not polished?

This is caused by the product structure, such as a cup with a small mouth and a big belly, especially the height of the cup is relatively high. Such products are difficult to polish, because the polishing wheel cannot be completely polished even if the polishing wheel enters the inside of the water cup, so such water cups can usually only be processed by electrolysis.

Stainless steel water cups that can be polished and electrolyzed have one thing in common, that is, the diameter of the cup mouth is greater than or equal to the inner maximum diameter of the inner liner of the water cup, and the inner liner cannot be abnormal. Such a water cup can achieve polishing and electrolysis at the same time.
