Spmil has manufactured air leak test rigs for auto components, viz, cylinder head, cylinder block, assembled cylinder head, assembled engine, petrol tank, or any pressurised/fluid reservoirs. They are designed to test the components for casting soundness such as cracks, sponginess, and joints. The procedure to test the component is to locate, clamp and plug the component in position. Filtered, regulated and lubricated air from frl unit is passed into the component till the pressure reaches a preset value and checked for leakage through a mass flow sensor and the result is displayed on dro. If the component is rejected, it is immersed into the emulsion tank where the point of leakage is observed visually with rotation of the rig. In case of ok component depressurisation, declamp followed by deplugging take place. This total operation is automatic without operator interference.
