72 Cavity PET Preform Mould | High-Output Solution for Large-Scale Production

High Production Efficiency for Large-Scale Manufacturing
The 72-cavity configuration significantly increases output per cycle, enabling stable and continuous high-speed production. It is ideal for mass production of bottled water, beverages, and edible oil packaging, helping manufacturers improve overall production efficiency.

 

Valve Gate Hot Runner System for Superior Molding Quality
Equipped with an advanced valve gate hot runner system, the mould ensures precise gate control with clean, smooth gate surfaces. This eliminates stringing and reduces the need for post-processing, resulting in consistent and high-quality preforms.

 

Optimized Cooling System for Shorter Cycle Time
The mould features an optimized cooling channel design that enhances heat transfer efficiency, effectively shortening the injection cycle. Uniform temperature distribution across all cavities ensures consistent dimensions and stable product quality.

 

Durable Materials for Long-Term Operation
Key components are manufactured from high-hardness, corrosion-resistant mould steel, combined with precision machining. This ensures excellent wear resistance, extended service life, and reduced maintenance, making it suitable for long-term, high-load production environments.

72 Cavity PET Preform Mold

 

Types of 72 Cavity PET Preform Mould

Standard 72-Cavity PET Preform Mould
Designed for high-volume production of standard preforms used in 0.5L to 1.5L bottles, this mould offers an optimal balance between output and operational flexibility.

 

72-Cavity Mould with Hot Runner System
Equipped with a heated manifold system that keeps PET in a molten state, ensuring uniform and waste-free delivery to all 72 cavities.

 

72-Cavity Mould with Cold Runner System
Uses a simpler, unheated runner system where excess PET solidifies and must be removed and recycled after each cycle.

 

Configurable 72-Cavity Moulds (Variable Cavity Operation)
Advanced moulds that can operate at different cavity counts (e.g., 48, 60, or 72 cavities) by selectively deactivating certain sections.

 

72-Cavity Moulds for Specific Applications
Tailored to produce preforms for particular bottle types, such as carbonated soft drinks, juice, hot-fill containers, or specialty packaging.

 

 

Applications of 72 Cavity PET Preform Mould

Beverage Bottles
One of the most prominent uses of PET preforms from 72 cavity molds is in the production of beverage containers. These include bottles for carbonated soft drinks, bottled water, fruit juices, energy drinks, and sports beverages. The material’s excellent gas barrier properties (especially against CO₂) help maintain carbonation and freshness, while its shatter-resistant and lightweight characteristics enhance safety and reduce transportation costs.

 

Food Containers
PET preforms are extensively used beyond beverages, particularly in packaging edible oils, vinegar, salad dressings, sauces, and ready-to-eat perishable foods.

 

Cosmetics and Personal Care Packaging
The cosmetics and personal care industry relies heavily on PET for packaging shampoos, conditioners, body washes, lotions, perfumes, and skincare products.

 

Pharmaceutical Packaging
In the pharmaceutical sector, PET preforms are used to manufacture bottles for liquid medications, syrups, eye drops, and oral solutions. The material’s high purity, low permeability to gases and moisture, and resistance to microbial growth make it ideal for preserving the efficacy and shelf life of medical products.

 

Industrial and Chemical Containers
PET’s strong chemical resistance makes it suitable for packaging industrial liquids such as solvents, acids, detergents, and cleaning agents. Containers made from PET preforms offer durability, leak-proof sealing, and resistance to corrosion—critical for safe handling and storage of hazardous substances.
