Multi-Cavity PET Preform Moulds: How to Choose the Right Cavity Count for Your Production
From 4-cavity to 144-cavity, the choice of cavity count is one of the most consequential decisions in preform production. Get it wrong and you are either under-producing or over-investing. This guide gives you the framework to choose correctly.
Understanding Cavity Count Options
Cavity Count vs. Output and Investment Level
Cavity Count Selection Guide
| Cavity Count | Machine Tonnage | Approx. Output/hr | Investment Level | Ideal For |
|---|---|---|---|---|
| 4–8 Cavity | 120–250T | 1,500–4,000 | Low | Trials, pharma small batches, specialty formats |
| 16–24 Cavity | 250–400T | 5,000–9,000 | Medium | Mid-volume CSD and water; SME bottling plants |
| 48 Cavity | 350–500T | 12,000–18,000 | Medium-High | High-volume water and CSD; standard platform |
| 72–96 Cavity | 500–700T | 20,000–32,000 | High | Large beverage producers; dedicated production lines |
| 128–144 Cavity | 700T+ | 40,000+ | Very High | Integrated production; major FMCG groups |
Important Consideration
More cavities does not always mean better economics. A 96-cavity mould requires a larger machine, higher maintenance capability, and a production volume to justify the investment. Hexamech always evaluates total cost of ownership — mould cost, machine cost, maintenance complexity, and product volume — before recommending a cavity count.
