8-cavity preform mold
8-cavity preform mold
An 8-cavity preform mold is a versatile injection tool for medium-volume production of PET preforms (28mm-110mm neck sizes), producing 8 identical preforms per cycle with typical cycle times of 28-35 seconds. It features precision H13 steel cores (HRC 48-52) and S136 cavity inserts for durability and corrosion resistance, along with a balanced cold runner system for uniform melt distribution. This mold configuration is perfect for beverage bottles, food jars, pharmaceutical containers, and specialty packaging requiring flexible production volumes with higher efficiency than 4/6-cavity molds.

This 8-cavity Preform Mold is a versatile high-performance injection tool engineered for medium-volume production of **PET preform (28mm-110mm neck)**s, including specialized options such as 5-gallon water bottle preforms and Food jar/pharmaceutical container preforms. It produces 8 identical preforms per cycle, with a stable 28-35 sec cycle time, and offers greater efficiency than 4/6-cavity alternatives for flexible production demands.
Equipped with a Balanced cold/hot runner system, it ensures uniform melt distribution across all cavities, minimizing material waste and enhancing preform consistency. The mold is constructed with H13/S136 steel inserts (HRC 48-52), delivering exceptional durability, corrosion resistance, and a long 3-5 million service life shots for reliable long-term production. Its Robust unscrewing demolding mechanism enables smooth, precise release of threaded preforms, while tight ±0.03mm dimensional tolerance guarantees consistent wall thickness and dimensional accuracy, critical for downstream blow molding. This mold is the ideal solution for manufacturers producing beverage bottles, food jars, pharmaceutical containers, and specialty packaging that require both efficiency and precision.
