Friends who have been following the editor for a long time will ask, didn’t you always say that the powder spraying process cannot pass the dishwasher test? Yes, before today's article, the editor has been insisting that the powder coating process cannot pass the dishwasher test. Because the editor has tested a variety of plastic powder coatings in order to meet customer requirements, and at the same time obtained many different plastic powder water cups from various channels.

After testing one by one, it turned out that none of the water cups sprayed with plastic powder passed the dishwasher test. Afterwards, the editor contacted a number of colleagues, and after confirming them one by one, the result was that there was indeed no stainless steel water cup with plastic powder that could pass the dishwasher test.So why did the editor say it was okay again today? Because a few hours before this article was written, a new food-safe plastic powder passed the dishwasher test. After 20 hours of continuous testing, the plastic powder has not changed, the surface is smooth and uniform, the color is consistent, and there is no discoloration, plaque, shedding and other phenomena.
