New Leak Detector Ensures the Quality of Castings
Our foundry produces high-quality castings for a wide range of applications. Some of the most complex components we manufacture are valves for vacuum pumps, which require completely airtight walls. Any defect could affect the pump’s functionality and therefore it’s essential for each valve to undergo 100% testing, ensuring maximum quality and reliability.
Previously, we outsourced airtightness testing to a partner company in England. However, this process extended the production cycle and increased overall costs. With the new ELD500 Leak Detector, we can now perform testing directly at MESIT, meeting the requirements of our customers.
How does the testing work? First we place a valve in the device, seal it and create a vacuum inside to simulate real operating conditions. Then we release a small amount of helium around the valve. Due to its extremely small molecular size, helium can penetrate even the tiniest leaks. The instrument accurately detects every trace of helium which enter the valve, enabling us to identify defects in the material, such as porosity or flaws in the sealing surfaces caused by machining.
