72 Cavity PET Preform Mould Successfully Completed for 13g Water Bottle Preforms

As global demand for bottled drinking water continues to increase, manufacturers are looking for production systems that combine high output, low energy consumption, and exceptional product consistency. Responding to these market requirements, Debodi Mould has successfully completed another 72 Cavity PET Preform Mould designed specifically for producing 13g PET water bottle preforms.

This project represents much more than simply increasing cavity numbers. It demonstrates our engineering capability in high-speed mould design, precision CNC machining, optimized cooling technology, balanced hot runner systems, and long-life mould manufacturing. For beverage manufacturers seeking maximum production efficiency and reliable long-term operation, this mould offers an ideal solution.

Why 72 Cavity PET Preform Moulds Are Becoming the Industry Standard

For large-scale beverage manufacturers, productivity is directly related to profitability. Compared with 24, 32 or 48 cavity moulds, a 72 cavity configuration significantly increases output while reducing production cost per preform.

The challenge is not simply adding more cavities. Every cavity must produce identical preforms with consistent dimensions, weight, transparency and neck finish. Even tiny deviations can affect bottle blowing quality, sealing performance and filling efficiency.

This is why high-cavity PET preform mould manufacturing requires advanced engineering experience rather than simply machining more cavities into one mould base.

Engineering Challenges Behind a 72 Cavity PET Preform Mould

1. Perfect Melt Distribution

One of the biggest challenges in high-cavity moulds is ensuring every cavity receives molten PET simultaneously with identical pressure and temperature.

Debodi Mould utilizes a carefully balanced hot runner system designed through flow analysis, allowing every cavity to fill uniformly. This minimizes weight variation and improves production stability.

2. Precision Machining

Every cavity, core and neck insert is manufactured using high-precision CNC machining combined with EDM and precision grinding. Tight machining tolerances ensure excellent interchangeability and easier maintenance throughout the mould's service life.

3. Optimized Cooling Design

Cooling efficiency directly affects injection cycle time. Our engineers develop independent cooling channels surrounding every cavity to ensure rapid and uniform heat removal.

Benefits include:

• Shorter production cycles
• Higher output per hour
• Reduced deformation
• Improved transparency
• Stable preform dimensions

4. Long Service Life

High-volume production requires moulds capable of operating continuously for years.

Debodi selects premium imported mould steels with excellent wear resistance, corrosion resistance and polishing performance, helping extend mould life while reducing maintenance costs.

Designed Specifically for 13g Water Bottle Preforms

The 13g PET preform is widely used for:

• 330ml water bottles
• 500ml drinking water bottles
• Small beverage bottles
• Lightweight packaging applications

Lightweight preforms help manufacturers reduce raw material consumption while maintaining bottle strength. However, lightweight production requires extremely accurate mould design because thinner wall sections leave less tolerance for processing errors.

Debodi Mould carefully optimizes gate design, cooling balance and venting to ensure excellent wall thickness distribution and bottle performance after blow molding.

Manufacturing Process at Debodi Mould

Every PET preform mould undergoes a rigorous manufacturing process:

1. Customer requirement analysis
2. 3D mould structure design
3. Mold flow simulation
4. High-speed CNC machining
5. EDM precision processing
6. Heat treatment
7. Precision grinding and polishing
8. Assembly by experienced technicians
9. Quality inspection
10. Injection testing
11. Customer approval before shipment

This standardized manufacturing workflow ensures every mould meets international quality standards before delivery.

Advantages for PET Bottle Manufacturers

• Higher production efficiency
• Lower production cost per bottle
• Excellent preform consistency
• Reduced injection cycle time
• Stable long-term operation

Quality Control at Every Stage

Quality is never inspected only at the final stage. At Debodi Mould, every manufacturing step is monitored through strict quality control procedures.

Our inspection includes:

• CMM dimensional inspection
• Hardness testing
• Concentricity inspection
• Cooling channel testing
• Hot runner inspection
• Assembly precision verification
• Injection trial testing
• Finished preform measurement
