72 Cavity PET Preform Mould Design & Manufacturing: Precision Engineering for High-Volume Production

Introduction

In the competitive world of PET preform manufacturing, efficiency and precision are critical. As a leading expert in 72 Cavity PET Preform Mould Design & Manufacturing, we specialize in high-cavitation moulds that maximize productivity while maintaining superior quality. This article explores the key aspects of PET preform mould design, manufacturing processes, and the benefits of high-cavity moulds for large-scale production.


Why Choose a 72-Cavity PET Preform Mould?

A 72-cavity PET preform mould is ideal for manufacturers looking to optimize output while reducing cycle times and operational costs. Key advantages include:

  • High Production Efficiency – More cavities mean higher output per cycle, making it perfect for large-scale PET bottle preform production.

  • Cost-Effective Manufacturing – Reduced per-unit cost due to economies of scale.

  • Consistent Quality – Precision engineering ensures uniform wall thickness, weight, and dimensions across all cavities.

  • Energy & Resource Savings – Higher cavitation reduces energy consumption per preform.


Key Considerations in 72 Cavity PET Preform Mould Design

Designing a high-performance 72-cavity PET preform mould requires expertise in:

1. Hot Runner System Optimization

  • A well-designed hot runner system ensures uniform melt distribution, minimizing material waste and cycle time.

  • Advanced nozzle and gate technology prevents drooling and stringing.

2. Cooling Channel Design

  • Efficient cooling is critical for maintaining fast cycle times.

  • Conformal cooling channels improve heat dissipation, reducing warpage and improving preform quality.

3. Cavity & Core Precision

  • High-grade steel (e.g., H13, S136, or Stainless Steel) ensures durability and corrosion resistance.

  • CNC machining and EDM processes guarantee tight tolerances for consistent preform dimensions.

4. Ejection System Reliability

  • A robust ejection mechanism prevents sticking and ensures smooth demolding.

  • Balanced ejection force avoids deformation in high-cavity moulds.
