An In-Depth Analysis of Glass Cup Manufacturing — Explosion-Proof Glass Cups Edition

Every cup tells a story, and life is filled with warmth. Hello everyone, "Dong Dong's Cup Talk" is here. Recently, due to the economic environment, I’ve had to spend more time seeking orders, which has slowed down the pace of content creation. http://umbottle.com/ProductsDetail-VB-10425.htmlAs a result, I’ve adjusted my updating approach—after sharing analytical content, I often follow up with product showcases due to the slower update cycle. This might leave some friends feeling unsatisfied.

I deeply apologize to everyone and hope you will continue to support me as always. I will quickly readjust and, in the future, share plenty of practical and in-depth analytical content with you all. At the same time, I also need your help in terms of business opportunities. http://umbottle.com/ProductsDetail-VB-10425.htmlHere, I bow to you in gratitude and wish everyone prosperity and abundant wealth.

Today, I bring you an in-depth analysis of glass cup manufacturing. Through this article, I hope to help you clearly understand what materials are used to make the glass cups you currently use and how to choose the right glass cup when making a purchase in the future. http://umbottle.com/ProductsDetail-VB-10425.htmlDue to the extensive content, I will divide it into multiple parts to share with you.

Some friends are particularly interested in explosion-proof glass cups, so let me share their secrets with you.

Explosion-proof ≠ unbreakable. Instead, it means "shattering without scattering."

Not breaking after a 2-meter drop? http://umbottle.com/ProductsDetail-VB-10425.htmlThat’s a tempered glass cup (based on the same principle as smartphone screens).

Core Process: Physical Tempering (Air Quenching)

Workflow: Formed cup body → evenly heated to the softening point → rapidly cooled with uniform high-pressure cold air.

Principle: The surface instantly cools and contracts, forming a high-pressure stress layer (>100 MPa), while the interior cools later, creating a tensile stress layer. http://umbottle.com/ProductsDetail-VB-10425.htmlThe balance of stress increases strength several times over.

Key Points: The base glass must be of high quality (often medium/high borosilicate is chosen); heating and cooling must be extremely uniform—otherwise, spontaneous breakage may occur. Case: A factory producing tempered cups had a high spontaneous breakage rate. http://umbottle.com/ProductsDetail-VB-10425.htmlInvestigation revealed that clogged nozzles in the cooling air system caused uneven cooling.

Role of Materials: Medium/high borosilicate glass itself offers high strength and excellent heat resistance, making it a good base material for tempering. http://umbottle.com/ProductsDetail-VB-10425.htmlHowever, explosion-proof performance is primarily achieved through the tempering process.
