Unveiling the Testing Procedures of Insulated Cups Before Leaving the Factory – Part VI

Every cup has a story, and life has its warmth. Hello everyone, "Dong Dong's Cup Talk" is here. Today, our editor has invited Director Li from our factory’s quality inspection department to specifically discuss the tests that stainless steel insulated cups undergo before leaving the factory. https://www.umbottle.com/ProductsDetail-VB-10528.htmlThe following content is based on Director Li’s narration, compiled by our editor. Due to the extensive content, the editor will share it in multiple parts.

Hello everyone, I’m Li Hang. I have been working in quality inspection at our factory for fifteen years. Over these years, I have led my team in testing millions of cups, ranging from orders for major domestic supermarkets to stringent projects exported to Europe, America, Japan, and South Korea. Almost every day, I deal with data related to salt spray, https://www.umbottle.com/ProductsDetail-VB-10528.htmldrop tests, and thermal insulation performance. At the same time, I am also a mother of a six-year-old boy, preparing warm water for him to take to kindergarten every day. Like all of you, what I care about most is whether a cup is truly safe, durable, and healthy.

Today, I would like to take you through the "graduation ceremony" that an insulated cup must undergo before leaving the factory, sharing insights both as a professional and as a mother.

Part Two: The "Keen-Eyed" Inspection Method in the E-commerce Era

In today’s global e-commerce landscape, many consumers rely on images and videos for "virtual inspections." As the person in charge of quality inspection, https://www.umbottle.com/ProductsDetail-VB-10528.htmlwe have also developed a set of inspection procedures tailored to e-commerce:

"One-Take" Unboxing: We record an unedited video starting from the moment the delivery box is opened, checking whether the product packaging is intact and free from crushing or deformation.

360-Degree All-Angle Showcase: https://www.umbottle.com/ProductsDetail-VB-10528.htmlThe cup is slowly rotated to meticulously film the mouth, base, welds, and paint finish, leaving no flaw hidden.

Key Function Demonstrations:

- Sealing Test: After filling the cup with warm water and tightening the lid, it is shaken vigorously to check for any leaks.

- Lid Operation Feel: The lid is repeatedly opened and closed to listen for a crisp sound and ensure the process is smooth without any sticking or stiffness.

- Accessory Inspection: https://www.umbottle.com/ProductsDetail-VB-10528.htmlAccessories such as straws and tea strainers are filmed separately to examine their material and craftsmanship.

Material Report Requests: For e-commerce products, I proactively request food-contact-grade material test reports (such as SGS’s GB 4806 series standard reports) from customer service. https://www.umbottle.com/ProductsDetail-VB-10528.htmlThis is the first line of defense in ensuring safety.
