Comprehensive Analysis of Plastic Water Bottle Production Process (Part 2)

There’s a story in every cup, warmth in every life—hello everyone, "Dong Dong's Cup Talk" is here! Today, we’re going to share how plastic water bottles are made. What key points should be noted during production? Are any of you curious? http://www.umbottle.com/ProductsDetail-VB-10505.htmlSome might ask, "Hey, don’t you usually produce stainless steel water bottles? How do you know about plastic bottle manufacturing?" Well, haha, our factory not only produces stainless steel water bottles but also plastic ones. In fact, we’ve been making plastic water bottles longer than stainless steel ones!

Our factory is equipped for both injection molding and blow molding, including one-step and two-step blow molding machines, as well as injection-stretch-blow molding (ISBM). http://www.umbottle.com/ProductsDetail-VB-10505.htmlSo, whether you need plastic mold development, product injection molding, bottle processing, or plastic product development, feel free to reach out!

2. Comparison of Food-Grade Plastic Material Properties

Material: PS, Temperature Range: 0-70°C, High Transparency, Low Impact Resistance, Applicable Processes: Injection Molding/Blister Molding

Material: PC, Temperature Range: -40-135°C, http://www.umbottle.com/ProductsDetail-VB-10505.htmlVery High Transparency, High Impact Resistance, Applicable Processes: Injection Molding/Blow Molding

Material: TRITAN, Temperature Range: -40-109°C, Ultra-High Transparency, Very High Impact Resistance, Applicable Processes: Injection Molding/Blow Molding/Extrusion Blow Molding

Material: PPSU, Temperature Range: -100-180°C, http://www.umbottle.com/ProductsDetail-VB-10505.htmlAmber Transparency, Very High Impact Resistance, Applicable Processes: Injection Molding/Blow Molding/Extrusion Blow Molding

Practical Case: Choosing Materials for Baby Bottles

If the bottle needs to hold hot water, PPSU (heat deflection temp: 207°C) is the best choice. http://www.umbottle.com/ProductsDetail-VB-10505.htmlHowever, note its high melt viscosity—special injection molding machines with a screw L/D ratio ≥24:1 are required.
