High-Efficiency 24-Cavity PET Preform Mold: High-Precision Neck Finish for Stable Production
ZSM Machinery proudly presents our High-Efficiency 24-Cavity PET Preform Mold—a precision-engineered tooling solution designed specifically for manufacturers requiring reliable, consistent preform production at medium volumes. The 24-cavity configuration represents an ideal balance between productivity and flexibility, making it the preferred choice for regional bottlers, contract manufacturers, and companies with diverse product lines . Our mold delivers exceptional dimensional accuracy, superior neck finish quality, and long-term stable production performance.
Key Features
1. Optimal 24-Cavity Configuration
Our 24-cavity mold offers significant advantages for medium-scale production:
Balanced efficiency: Delivers optimal output without the higher investment of larger cavitation systems
Production capacity: Suitable for 15-23 second cycle times depending on preform specifications
Versatile applications: Ideal for beverage, pharmaceutical, food, and personal care packaging
Cost-effective solution: Moderate production scale with affordable maintenance requirements
2. High-Precision Neck Finish Engineering
The neck finish is the most critical area for preform quality, determining sealing performance and closure compatibility. ZSM's molds incorporate specialized features for superior thread formation :
Precision thread-forming inserts manufactured from imported nitride steel with high hardness for extended usage in critical thread-forming areas
International standard screw neck designs ensuring compatibility with global closure systems
Advanced dipole taper localization technique ensures each cavity self-clamps independently for perfect concentricity
Wall thickness variation maintained below 0.10mm between maximum and minimum sections
3. Premium Material Construction
ZSM molds are constructed from high-quality materials for extended mold life and consistent performance :
4. Advanced Valve Gate Hot Runner System
Our 24-cavity molds feature state-of-the-art valve gate hot runner technology :
Individual temperature control for each nozzle with independent thermocouples, maintaining accuracy and preventing defects such as bottom whitening or drawdown
Balanced filling across all 24 cavities ensuring consistent preform weight and dimensions
Valve gate design with automatic drop eliminates tail trimming, saving labor costs
Weight difference between cavities: Maintained below 0.3 grams
Italian technology heating components from leading brands ensure reliability
5. Optimized Cooling System for Stable Production
Efficient cooling is essential for achieving fast cycle times and consistent preform quality :
Spiral cooling channels in cavity inserts for rapid, uniform heat extraction
Enhanced cooling in neck area where material thickness is greatest
Precision cooling water distribution ensuring balanced temperature across all cavities
Cycle times as low as 15 seconds with proper water chiller and injection machine
6. Precision Engineering for Consistent Quality
Self-locking cavity design: Each cavity self-clamps independently, ensuring high precision and fewer defects
Off-center adjustment system: Ensures preform thickness difference < 0.05-0.10mm
Concentricity control: Advanced alignment ensures uniform material distribution
High-precision CNC machining: All components manufactured with micron-level accuracy
