Today’s article seems to have been written before. Friends who have been following us for a long time, please don’t cross it out, because the content of today’s article has changed compared to the previous article, and there will be more examples of craftsmanship than before. At the same time, we believe that colleagues in the industry, especially those engaged in foreign trade, will definitely like this article, because this content is very helpful to them.
Below we will use a simple process comparison to tell our friends which parts of the surface spraying process of stainless steel water cups cannot be put into the dishwasher.
Can the spray painting process, including gloss paint, matte paint, hand paint, etc., pass the dishwasher test? Can
Can the powder coating process (plastic spray process), including semi-matte surface and full matte surface, pass the dishwasher test? Can
Friends who have been following us for a long time may ask, haven’t you always said that the powder spraying process cannot pass the dishwasher test? Yes, before today’s article, we have always insisted that the powder spraying process cannot pass the dishwasher test, because in order to meet the requirements of customers, we have tested a variety of plastic powder coatings and also obtained several plastic powder coatings from various channels. Different plastic powder-coated water cups were tested one by one. As a result, none of the plastic powder-coated water cups passed the dishwasher test.
Afterwards, we contacted many colleagues and confirmed one by one. The result was that there was indeed no stainless steel water cup sprayed with plastic powder that could pass the dishwasher test. So why do we say yes again today? Because a few hours before we wrote this article, a new food-grade safe plastic powder passed the dishwasher test. After 20 consecutive hours of testing, the plastic powder showed no change, the surface was smooth and even, and the color was consistent. There is no discoloration, plaque, peeling, etc.
Can the PVD (vacuum plating) process, including solid color effects, gradient color effects, etc., pass the dishwasher test? Can’t
Can the plating process pass the dishwasher test? Can’t
Can the thermal transfer process pass the dishwasher test? Yes, but there are conditions. After heat transfer, a protective layer such as varnish must be sprayed on the pattern again, so that it can pass the dishwasher test, otherwise the pattern will discolor and fall off.
Can the water transfer printing process pass the dishwasher test? Yes, just like thermal transfer, you need to spray a protective layer again after transferring the pattern.
Can the anodizing (or electrophoretic) process pass the dishwasher test? No, the anode coating will react chemically with the dishwasher detergent, causing the surface of the coating to become dull.
