Hot Runner Cavity Balance Software
Intelligent Imbalance CorrectionCav-Bal®PRO
Cav-Bal® is specialist software developed to scientifically calculate the hot runner tip adjustments required to balance cavities.
What Is Cav-Bal®?
Cav-Bal®PRO is proprietary cavity balance software developed by Moulding Optimisation Ltd for correcting hot runner cavity imbalance in multi-cavity injection moulds. It is used during mould qualification, process validation, and troubleshooting to establish uniform cavity filling and stable production conditions.
What Cav-Bal® Does
Cav-Bal® analyses short-shot cavity weight data and calculates:
-
Required hot runner tip temperature corrections
-
Cavity-to-cavity imbalance percentage
- The optimum ΔT for the balanced tip profile
Cav-Bal® can achieve a measurable <1% cavity imbalance on your hot runner moulds; results are limited only by the resolution of the hot runner controller.
“For anyone involved in process development, validation or process optimisation, Cav-Bal is an invaluable tool. It has become an essential part of my workflow, and I genuinely wouldn't attempt to balance a mould without it."
"Cav-Bal will pay for itself in no time at all. Not only that, it provides excellent back up documentation that can be saved and printed out for your tools development records."

Why Cavity Balance Matters
Unbalanced moulds can result in:
-
Dimensional variation
-
Cosmetic differences between cavities
-
Uneven packing
-
Gate freeze inconsistency
-
Increased scrap
-
Extended mould trials
-
Ongoing “tuning” during production
Traditional tip tuning is often iterative and experience-based.
Cav-Bal® converts cavity weight data into calculated adjustments using a structured Design of Experiments methodology — removing guesswork and reducing trial time.
Where Cav-Bal® Is Used
Cav-Bal® is suitable for:
-
Initial mould qualification
-
Scientific Injection Moulding studies
-
Medical validation (IQ / OQ / PQ support)
-
Routine maintenance re-balance
-
Troubleshooting cosmetic or dimensional variation
-
High cavity count hot runner systems
It is particularly effective on:
-
Valve-gated hot runners
-
Multi-cavity tools (from 2 to 64 cavities)
-
Engineering polymers
-
Medical and high-tolerance applications
The Engineering Philosophy Behind Cav-Bal®
Cav-Bal® was developed from real-world injection moulding experience to reduce the time it takes to balance cavities on multi cavity hot runner moulds.
It does not replace scientific injection moulding although data collection is identical to the traditional Cavity Balance Study. It takes that data and gives the Engineer the exact hot runner tip settings to use, enabling the best possible imbalance, with the best possible ΔT, in the shortest possible time.
Cav-Bal® integrates naturally into a structured SIM approach and supports validation-driven environments.
