4-Cavity Preform Mold
4-Cavity Preform Mold
A 4-cavity preform mold is an ideal injection tool for small-volume production, prototype development, and product trials, producing 4 identical preforms per cycle with typical cycle times of 18-25 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 (or optional hot runner) for uniform melt distribution. This mold configuration is perfect for customized PET preforms used in specialty packaging, medical containers, and limited-edition beverage bottles requiring flexible production volumes.

This4-cavity preform mold is a precision-engineered small-batch production solution optimized for PET preform production, including specialized wide-mouth preform molding for customized PET preforms used in specialty packaging, medical containers, and limited-edition beverage bottles. It is ideal for small-volume production, prototype development, and product trials, producing 4 identical preforms per cycle with a stable 18-25 sec cycle time.
Equipped with a Balanced hot/cold runner system (with optional hot runner upgrade), it ensures uniform melt distribution across all cavities, minimizing material waste and enhancing preform consistency. Constructed with H13/S136 steel inserts (HRC 48-52), the mold delivers exceptional durability, corrosion resistance, and a long 3-5 million service life shots for reliable long-term production. Its 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 performance. This versatile mold balances efficiency and flexibility, making it the ideal choice for manufacturers seeking to produce high-quality, customized PET preforms across diverse packaging applications.
