Coverley - Production Engineer}1/FH.2.10.37. ALUMINIUM ALLOY BEARINGS. In reply to By.29/N.23.9.37. we are now looking into the question of producing the Main and Connecting Rod Bearing Sheels by the Centrifugal Casting process which should materially assist in reducing our present scrap caused by concealed Blow Holes. Production of Bearings by this method should ensure a closer grain than gravity Die Castings with consequent reduction of porosity, and in addition we anticipate being able to cast the sheels closer to finished size than at present which will reduce the material cost . Another point for consideration is the fact that Centrifugal Casting should ensure consistent results which will avoid machine energy being wasted on Bearings already scrap due to concealed defects.
