High-Efficiency Preform Production: HPET 5000-488 in Ghana Customer Application Case

With the continuous growth of the global plastic packaging industry, high-efficiency and precision injection molding systems have become essential for PET preform manufacturing. Recently, the HPET 5000-488 injection molding machine was successfully delivered to a customer in Ghana for high-volume production of PET bottle preforms, demonstrating strong stability, fast cycle performance, and excellent product consistency.

Project Overview

The Ghana customer required a reliable solution for mass production of 30mm neck PET preforms used in beverage packaging. After technical evaluation and configuration optimization, the HPET 5000-488 was selected due to its high clamping force, multi-cavity capability, and stable injection performance.

The production parameters of this project are as follows:

• Preform weight: 12g
• Cavity number: 96 cavities
• Neck finish: 30mm
• Cycle time: 13.5 seconds

These parameters place high demands on injection speed, plasticizing efficiency, mold balance, and cooling system performance. The HPET 5000-488 is designed to meet exactly these requirements.

Machine Performance Advantage

The HPET 5000-488 is engineered for high-output PET preform production. In this application, it demonstrates several key advantages:

First, the machine delivers excellent injection stability even under a 96-cavity mold configuration. Maintaining consistent weight and dimensional accuracy across all cavities is critical, especially for lightweight 12g preforms. The system ensures uniform melt distribution, reducing variation and improving product quality consistency.

Second, the optimized plasticizing system supports rapid and stable material melting, enabling a short cycle time of 13.5 seconds. This significantly improves production efficiency and reduces overall manufacturing cost per unit.

Third, the machine's high clamping force ensures mold stability during high-pressure injection, preventing flash and ensuring precise neck finish formation at 30mm specification. This is particularly important for beverage-grade PET applications where sealing performance is critical.

Production Stability and Efficiency

During continuous operation, the HPET 5000-488 maintained stable output with minimal fluctuation in cycle time and product weight. The cooling system worked efficiently to support fast demolding, which is essential for high-cavity molds like 96-cavity PET preform tooling.

For the Ghana customer, this translates into higher daily output, reduced downtime, and improved overall production efficiency. The system is well-suited for large-scale beverage packaging manufacturers aiming to expand capacity in competitive markets.

Conclusion

The successful application of the HPET 5000-488 injection molding machine in Ghana demonstrates its capability in high-cavity, high-speed PET preform production. With a configuration of 96 cavities, 12g preform weight, 30mm neck finish, and a 13.5-second cycle time, the system achieves an excellent balance between productivity, stability, and product quality.

This case further highlights the machine's suitability for global PET packaging markets, particularly in regions where efficiency and reliability are key to production competitiveness.
