A Beverage preform mold must cover a broad spectrum-from still water to carbonated drinks-demanding flexibility without sacrificing quality.
Broad Resin Compatibility
This Beverage preform mold handles a wide range of PET grades, including standard bottle grade, fast-reheat, and carbonated soft drink grades. The hot runner is tuned with a moderately sized gate and neutral nozzle profiles that avoid over-shearing sensitive materials while still providing adequate backpressure for mixing.
Customizable Neck Options
The Beverage preform mold platform supports a library of neck ring inserts covering all major ISBT standards. You can pivot from a standard water neck to a flavor-cap bottleneck simply by changing the neck ring cassette. This allows you to respond quickly to market trends without investing in an entirely new mold.


Consistent Reheat and Blow Performance
A Beverage preform mold produces preforms with a controlled axial wall thickness gradient-thinner towards the neck and thicker near the gate-which is ideal for infrared reheat systems. The preform absorbs heat uniformly in the blow molder oven, resulting in a bottle with even material distribution and high top-load strength.
Easy Integration with Auxiliary Equipment
The Beverage preform mold is designed with standard robot pick-up patterns and cooling station interfaces. It can seamlessly integrate with post-mold cooling robots that further reduce the preform temperature before discharge, increasing your line speed without adding floor space. Your Beverage preform mold becomes the core of a streamlined production cell.
Manufacturing for the global beverage industry demands a PET preform mold that can meet all ISBT standards without compromise.
ISBT Standard Neck Ring Accuracy
The neck ring inserts in this PET preform mold are machined to replicate bottle finishes such as PCO 1881, 30/25, and 29/25 with thread lead error below 0.01 mm. This guarantees a perfect seal with capping equipment at speeds exceeding 60,000 bottles per hour, eliminating leakage risks that could result in costly recalls.
