Mineral Water Bottle Preform Mold

Designed for mass production of mineral water bottle preforms, using high-quality mold steel and precision machining technology. The cavity surface is mirror polished to ensure smooth preform appearance without visible streaks or scratches.
Optimized runner system and cooling structure shorten the molding cycle, improve injection efficiency, and keep production energy consumption under control.
The mold features convenient assembly and maintenance, with stable positioning accuracy to reduce issues such as eccentricity and uneven wall thickness during long-term continuous production.
Supports multi-cavity customization and can match different mineral water bottle preform sizes, meeting the requirements of high-volume bottle blowing production.

Q: Do you support modification of bottle neck standard to match different bottle caps?
A: Yes. We can redesign neck finish dimensions to fit standard PCO, 30/25 and other custom cap specifications without redesigning the entire mold assembly.

Q: What's your solution if burrs or flash appear on preforms after long-time running?
A: We provide professional guidance for clearance inspection and maintenance. If structural optimization is required, our technical team can offer targeted upgrade proposals.

Q: What's your maximum cavity number you can produce for mineral water bottle preform molds?

A: We develop multi-cavity preform molds ranging from 48 cavities to 144 cavities. The layout design will be customized according to your injection machine clamping force and daily production capacity goals.

Q: What tolerance standard do you follow for PET bottle preform molds?
A: We execute international precision tolerance standards for critical parts. All key dimensions are inspected with coordinate measuring machines to keep preform uniformity during continuous operation.
