What is the purpose and standard for stainless steel water cups to pass dishwasher tests? (I)

Hello everyone, "Dong Dong Talk Cup" is here. Today's article probably won't be read that much, because today's content is not that valuable for ordinary consumers. As more and more buyers and brand owners are testing the products of water cup manufacturers before they leave the factory,http://www.zhanyict.com/en/ProductsDetail-VB-10500.html passing the dishwasher test has also become a requirement of many brands.

However, the editor found that both the production factory and the brand buyers seem to have a rather one-sided understanding of stainless steel water cups passing the dishwasher test. So today, the editor will popularize why stainless steel water cups must pass the dishwasher test before leaving the factory? http://www.zhanyict.com/en/ProductsDetail-VB-10500.htmlIs the test content only for the surface coating of stainless steel water cups? Are stainless steel water cups that pass the dishwasher test of better quality?

First of all, the purpose of the dishwasher test for stainless steel water cups is not simply to test the surface coating of the stainless steel water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10500.htmlThe purpose of the test includes:

Corrosion resistance test: Check whether the water cup will corrode or rust after contact with detergent and hot water in the dishwasher.

Heat resistance test: Ensure that the water cup will not be deformed or damaged in the high temperature environment of the dishwasher. http://www.zhanyict.com/en/ProductsDetail-VB-10500.htmlHere we only target the plastic and silicone parts used in stainless steel water cups.

Coating durability: For cups with special coatings, test whether the coating remains intact and has stable color after multiple dishwashings.

Sealing test: For water cups with lids, test whether the sealing of the lids will be weakened by the washing process of the dishwasher.

Secondly, what are the standards for passing the dishwasher test?

No corrosion: http://www.zhanyict.com/en/ProductsDetail-VB-10500.htmlThe cup should not have any corrosion or rust after testing.

No damage and deformation: The shape and structure of the water cup should remain intact after high temperature and long-term washing.

Integrity of coating: The coating has no peeling, cracking or color difference and has the same gloss and smoothness.

Due to space constraints, this is the end of this issue. Friends who are interested in this topic are welcome to follow Uncle Dong. I will push the next issue to you as soon as possible. http://www.zhanyict.com/en/ProductsDetail-VB-10500.htmlThank you.
