Taize has installed a second automated air tightness testing line at the Yuhuan factory, bringing total testing capacity in line with our 5 million unit annual production volume.
Every thermostatic valve, air vent valve and radiator plug now passes a 1.6 MPa air tightness test before packing. The new line records the result of each individual part against its production batch, so a test report can be produced for any shipment.
Leakage is the most common after-sales complaint about radiator parts, and it is almost always caused by porosity in the casting or a damaged seal rather than by the design. Testing every single part is the only reliable way to remove that risk before the goods leave the factory.
Customers who require documentation can request the batch test report together with the shipping documents. Third-party inspection by SGS or DNV can also be arranged before container loading.
