Manufacturers are continuously looking to save on production costs while maintaining high-quality packaging. The aerosol can market is no different; however, these cans are especially sensitive to metal thickness reduction due to overpressure inside the cans. In addition, any leak testing solution of aerosol cans must meet the requirements outlined in the ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road).

Bonfiglioli Engineering, a global leader in the design and construction of packaging inspection systems for various industries was awarded a project to manufacture a new generation of KBA systems with high-speed inspection capabilities which exceeded the previous speed threshold. This innovative solution for 100 per cent in-line leak testing is equipped with the ESA (Enhanced Sensitivity Algorithm) which provides leak testing for low-thickness aerosol cans at speeds of up to 800 aerosol cans per minute.

The KBA Non-Invasive, Non-Destructive leak inspection machine for empty aerosol cans is available in various configurations: 24, 36, 48 and the recently delivered 60 testing heads. This versatile design ensures that customer’s production speeds are easily matched, even for cans with internal pressurization levels that range up to 15BarG / 220PSI.

The KBA system is designed to meet and exceed the needs of the customers while meeting global regulatory standards such as those outlined in FEA guidelines, ADR, DOT requirements (49 CFR 173.306). Bonfiglioli Engineering KBA leak testing machines are engineered to be in compliance with Industry 4.0 requirements with the ability to monitor pneumatical and electrical energy consumption. Other system options include MES (Manufacturing Execution System connection, also referred to as OEE) and Statistical Process Control that reduces deviations for a better yield control and challenge leak mode.
