High-Precision 144 Cavity PET Preform Mold Molding Performance
1. Stable Weight Accuracy
The 144-cavity mold places higher demands on weight control. Optimized runners and balanced cavity feeding ensure stable preform weight, reducing material fluctuations and improving consistency in subsequent blow molding.
2. Uniform Wall Thickness Distribution
A carefully designed cooling structure and cavity layout achieve a more uniform wall thickness distribution. Stable wall thickness helps to better control the preform's performance during blow molding, resulting in a more robust bottle structure that better meets brand quality requirements.
3. Clean and Transparent Surface
The finely machined cavity surface offers excellent transparency and smoothness. High-quality preforms enhance the appearance of the finished product, which is crucial for brand image in the beverage and cosmetics industries.
4. Stable and Reliable Mass Production
This mold maintains stable performance during mass production. Optimized temperature control systems and mold structure minimize batch variations, helping companies maintain a consistently reliable supply.

The mold is applicable to various machine models, subject to confirmation by the project engineer.
Designed for precise control and sustained performance
Precision Machining for Stable Performance
Every component of the 144-cavity PET preform mold is produced through high-accuracy CNC and EDM machining. This ensures tight tolerances on core and cavity dimensions, allowing the mold to maintain consistent preform quality even under long production runs.
High-Strength Materials for Long Service Life
The mold structure is built with corrosion-resistant steels and wear-resistant inserts to handle continuous high-temperature injection cycles. These materials help reduce deformation, extend mold lifespan, and keep maintenance costs under control.
Optimized Cooling Layout for Lower Cycle Times
A carefully designed water-channel layout provides uniform cooling across all 144 cavities. This reduces cycle time, stabilizes preform weight, and minimizes defects such as haze or uneven wall thickness, making the mold suitable for high-output production environments.
Design Your PET Preform Mold to Fit Your Production Needs
Adjustable Preform Weight
Our molds can be customized for different preform weights to meet various bottle designs. From lightweight options to heavier preforms, each mold is designed to ensure consistent weight and reliable performance.
