Comprehensive Analysis of Aluminum Cup Manufacturing — Authoritative Q&A Part 2

Every cup holds a story, and life is filled with warmth. Hello everyone, and welcome to "Dong Dong's Cup Talk" Many friends already know that I primarily specialize in producing various types of stainless steel cups and plastic cups. https://www.umbottle.com/ProductsDetail-VB-10100.htmlAlthough I previously shared an in-depth analysis of glass cups, it was made possible with the help of friends. If you encounter any issues when purchasing or developing stainless steel or plastic cup products, feel free to message me privately. I am more than happy to provide you with dedicated assistance.

Perhaps due to the season or the arrival of another peak sales period, I have recently received numerous inquiries from around the world about purchasing aluminum cups. https://www.umbottle.com/ProductsDetail-VB-10100.htmlThis inspired me to share some insights about aluminum cups. Considering my limited expertise in this area, I have invited Mr. Xuan, who has nearly 20 years of experience in operating an aluminum cup factory, to elaborate on the intricacies of aluminum cup manufacturing.

6. How to Identify Safe Materials:

- Check Certifications: Look for GB 4806.9-2016 (Chinese food contact standard) and EU 1935/2004. https://www.umbottle.com/ProductsDetail-VB-10100.htmlThe inner wall should have a uniform and smooth coating (not the raw metallic color).

7. Causes and Solutions for Blackening:

- Surface Blackening: Often caused by oxidation from hand sweat or oils. Wipe with a neutral detergent and soft cloth.

- Inner Wall Blackening: Result of corrosion from long-term exposure to acidic beverages (e.g., juice, coffee). Discontinue use immediately!

8. Daily Maintenance Guidelines:

- Avoid using steel wool or strong acid/alkaline cleaners.

- Do not store acidic beverages (pH < 5) for more than 4 hours.

- Dry thoroughly after cleaning to prevent water stains.

9. Lifespan and Replacement:

- Under normal use (no physical impact, neutral beverages), https://www.umbottle.com/ProductsDetail-VB-10100.htmlthe lifespan is approximately 5-8 years. Replace immediately if the inner coating shows scratches, discoloration, or peeling.

10. Is It Safe for Infants and Toddlers to Use Aluminum Cups?

- Not Recommended! Infants and toddlers have underdeveloped metabolic systems, https://www.umbottle.com/ProductsDetail-VB-10100.htmlmaking them more vulnerable to potential aluminum ion risks. Opt for cups made of glass, PPSU, or 316L stainless steel for superior safety.

Behind every aluminum cup lies the culmination of materials science and precision manufacturing. https://www.umbottle.com/ProductsDetail-VB-10100.htmlAs a practitioner in this industry, we always prioritize safety and quality.
