Q: What is Cav-Bal®PRO?
A: Cav-Bal®PRO is an advanced cavity balancing software designed to resolve cavity imbalance in injection moulding. It provides precise, data-driven adjustments for hot runner tip settings, ensuring uniform cavity filling, consistent part weights, and improved process stability in multi-cavity injection moulds. It can balance up to 64 cavities.

Q: How much is Cav-Bal®PRO?
A: Cav-Bal®PRO is £349 + VAT for a single 12 month license.

Q: Can I get Cav-Bal®PRO for free?
A: Cav-Bal®PRO is not available as a permanently free product. However, a full-featured 30-day trial is available to allow evaluation before purchase.

Q: What is cavity imbalance in injection moulding?
A: Cavity imbalance occurs when multiple cavities in a mould do not fill evenly during the injection moulding process. This can lead to part weight variations, inconsistent packing pressures, dimensional inaccuracies, increased scrap rates, and quality control issues.

Q: Is Cav-Bal®PRO AI, or does it use AI?
A: No.

Q: How does Cav-Bal®PRO correct cavity imbalance?
A: Cav-Bal®PRO uses scientific injection moulding principles, including Design of Experiments (DoE) methodology and proprietary algorithms, to calculate the optimal hot runner tip adjustments needed to achieve cavity-to-cavity balance.

Q: Does Cav-Bal®PRO work on non-valve gated moulds?
A: Cav-Bal®PRO is primarily designed for valve-gated moulds but can also be used with non-valve gated hot runner moulds although the results may not always be as accurate.

Q: What is SIM Workbench?
A: SIM Workbench is a module within the Cav-Bal software, it is a suite of Scientific Injection Moulding tools and calculators for developing injection moulding processes.

Q: What types of injection moulds does Cav-Bal®PRO support?
A: Cav-Bal®PRO is specifically designed for valve-gated multi-cavity hot runner moulds. It provides precise balancing for hot runner systems, optimizing fill time uniformity, cavity pressure balance, and material distribution. It is not intended for sequential filling configurations.

Q: Does Cav-Bal®PRO require in-mould sensors?
A: No, Cav-Bal®PRO does not require any pressure, temperature, or flow sensors inside the mould cavities. It works by analysing shot-to-shot cavity weight variations and other standard process data, enabling engineers to make hot runner tip adjustments based on calculated recommendations.

Q: Can Cav-Bal®PRO be used with both thermoplastics and thermosets?
A: No, Cav-Bal®PRO is designed for thermoplastic injection moulding only.

Q: Does Cav-Bal®PRO integrate with injection moulding machines?
A: No, Cav-Bal®PRO is a standalone software tool. Users enter component weights from a short shot study, and the software generates precise recommendations for adjusting hot runner settings.

Q: How long does it take to use Cav-Bal®PRO to balance my injection moulds?
A: It depends on how many cavities you have and how long it will take you to weigh the parts for the study. The software typically requests weight data from 3 shots at each step, but this can be reduced to 1 shot per step if you are confident there is minimal shot-to-shot variation. A study can typically be completed from around 20 minutes and upwards to achieve a well-balanced result.

Q: How quickly can I see improvements in cavity balance using Cav-Bal®PRO?
A: Engineers will typically see improvements in cavity balance immediately after implementing the recommended hot runner tip adjustments. Significant reductions in part variability and scrap rates can often be achieved within a single setup cycle.

Q: Can Cav-Bal®PRO reduce scrap rates and cycle times?
A: Yes, by improving cavity balance, Cav-Bal®PRO helps reduce reject rates, eliminate overpacked and underfilled cavities, and optimise fill times—all of which contribute to reduced cycle times and increased productivity.

Q: Does Cav-Bal®PRO replace other scientific moulding techniques?
A: No, Cav-Bal®PRO is a complementary tool designed to work alongside scientific injection moulding practices such as injection speed studies, hold pressure studies, clamp force studies, cooling time studies, and cavity balance studies. It effectively replaces the traditional cavity balance study by providing a more structured and data-driven approach. The software also includes exportable data and a PDF report (PRO version) to support your existing documentation if required.

Q: How do I know if my moulding process needs Cav-Bal®PRO?
A: If you are running a multi-cavity hot runner mould and want to achieve the best possible cavity balance, Cav-Bal®PRO provides a clear, scientific approach. It is particularly useful where there is inconsistent cavity fill, difficulty achieving balance, or a narrow process window. It enables precise optimisation of hot runner tip settings without the need for in-cavity sensors.
