Cav-Bal®PRO – Advanced Cavity Balancing for Multi-Cavity Injection Moulding

Cav-Bal®PRO is designed to solve one of the most persistent challenges in injection moulding: cavity imbalance, also referred to as flow imbalance, fill imbalance, shot-to-shot variation, cavity-to-cavity inconsistency, mould filling imbalance, hot runner balancing, and multi-cavity process variation. In short, if you get your cavity balance perfect, every other element of your injection moulding process becomes easier.

Used alongside your existing Scientific Injection Mouding procedures, this software applies cutting-edge scientific principles to provide precise, repeatable adjustments for hot runner tip settings, and therefore flow control, ensuring optimal cavity balance, uniform fill times, balanced pressure distribution, and improved part weight consistency. By achieving proper balance, Cav-Bal®PRO enhances process control, reduces scrap rates, improves shot-to-shot consistency, and increases overall moulding efficiency.

A Scientific Approach to Cavity Balancing

Cav-Bal®PRO stands out by offering a structured, data-driven, and repeatable approach to correcting cavity fill imbalances in multi-cavity, valve-gated hot runner moulds. Traditional methods often depend on the subjective judgement of process engineers, leading to inconsistent results, prolonged cycle development, and inefficient troubleshooting.

Cav-Bal®PRO eliminates this guesswork by integrating:

• Design of Experiments (DoE) methodology to systematically evaluate balance corrections
• Proprietary algorithms to calculate exact adjustments for hot runner tip temperature settings
• Quantitative data analysis for consistent, optimised cavity filling and reduced part variability

By leveraging scientific injection moulding techniques, Cav-Bal®PRO enables engineers to:

• Achieve uniform cavity fill across multi-cavity tools to the best imbalance % possible, in the shortest time possible.
• Optimise hot runner and valve gate performance
• Reduce cycle time while maintaining quality
• Improve overall productivity and reduce troubleshooting time
