“The Birth Story of a Qualified Stainless Steel Insulated Cup (Part One)”

There are stories in the cup, and warmth in life. Hello everyone, "Dong Dong's Cup Talk" is here. As the number of followers on my Xiaohongshu account "Dong Dong Talks Cups" increases, I’ve received more and more inquiries from friends in the comments. https://www.zhanyict.com/en/ProductsDetail-VB-10538.htmlHowever, I noticed a common issue in these inquiries: most people focus on the undesirable aspects of the inner liner of newly purchased insulated cups, while few raise concerns about other parts or accessories of the cup.

Today, I’ll share in detail what a qualified insulated cup should look like. Besides quality requirements for the inner liner, what other standards should be met for other parts and accessories? https://www.zhanyict.com/en/ProductsDetail-VB-10538.htmlSince there’s a lot to cover, I’ll break it down into multiple separate posts to share with everyone.

I. What Information Should a Qualified Insulated Cup’s "ID Card" Include?

When a qualified insulated cup leaves the factory, it must undergo strict quality control. Its standards should far exceed "usable" and aim for "excellence." https://www.zhanyict.com/en/ProductsDetail-VB-10538.htmlHere are the essential dimensions it must meet:

1. Appearance Requirements:

Qualified Standards: The cup body should be round and properly shaped with smooth lines. The surface finish (whether sprayed, painted, electroplated, or powder-coated) should have uniform color, no dents, scratches, https://www.zhanyict.com/en/ProductsDetail-VB-10538.htmlor noticeable defects. Particles and impurities should fall within national standard requirements, and shrinkage marks should be strictly controlled.

Negative Examples: Uneven coloring on the cup body, visible "orange peel" effect when viewed from the side; dust particles visibly trapped in the paint (and numerous); or localized areas where the paint film is too thin, faintly revealing the underlying metal color. https://www.zhanyict.com/en/ProductsDetail-VB-10538.htmlThese issues reflect an unclean spraying environment, improper paint mixing, or poor spraying techniques.
