Introduction
In industries where aluminium castings play a key role—such as the energy sector, electric mobility and energy storage—the ability to guarantee tightness is essential.
To respond to these increasing market demands, Fonderia Taroni has implemented helium leak testing within its production process, one of the most sensitive methods available to detect microporosity in critical components.
This new capability strengthens the company’s role as a technologically advanced partner, capable of delivering components with high reliability and consistent performance.
Why Helium Leak Testing Matters
Helium, thanks to its extremely small atomic size and inert behaviour, can pass through micro-defects that other test methods fail to detect. This makes helium leak testing a widely recognised solution for components such as:
-
current transformers and electrical insulators
-
enclosures for electrical and electronic systems
-
pressure-related elements
-
housings used in e-mobility
-
parts used in energy storage systems
What Fonderia Taroni Provides Today
Fonderia Taroni now performs:
-
helium leak tests using mass spectrometry
-
complete, traceable test reports for every inspected component
-
high-sensitivity non-destructive testing suitable for complex geometries
-
leak rate measurement and evaluation according to customer requirements
All equipment and procedures follow standardised internal methods, ensuring consistent results and accurate measurements.
Benefits for Customers
1. Documented and traceable quality controls
Each tested part is accompanied by clear measurement data, useful for audits, technical discussions and product validation.
2. Lower risk of non-conformities
Potential issues are identified before components reach the customer, reducing rework, delays and supply-chain interruptions.
3. Higher reliability for critical applications
Helium leak testing supports the performance of electrical insulators, housings and other components installed in high-demand environments.
4. Faster development cycles
With testing performed in-house, feedback for prototypes and new designs is significantly quicker.
Main Applications
This advanced testing service is especially suited for:
-
current transformers and electrical insulators
-
medium- and high-voltage equipment
-
power electronics structures
-
components used in electric cooling systems
-
battery system housings and energy storage applications
The company is also evaluating future applications in aerospace, hydraulics and medical sectors.
Conclusion
By integrating helium leak testing within its processes, Fonderia Taroni strengthens its commitment to delivering reliable aluminium castings for the most demanding markets.
This value-added service enhances support for current customers and opens new opportunities in sectors where performance and precision are essential.
