Die Casting of Major Engine Components

Abstract

‘Aluminum and automobiles’ are closely linked to the progress and development of the automobile industry. Moreover, at this time when energy conservation is the prime requisite, manufacturers are compelled aggressively to pursue weight reduction and compactness in designs of future automobiles. As a result, lightweight alloys, in particular aluminum and magnesium, are in ever increasing use as materials for automobile components. A very good example of the extent of lightweight alloys used in automobiles was very evident at the 1976 international conference on aluminum and the motor car held in West Germany. On display were aluminum bumpers, truck cabs, door panels, bonnets, steering columns and numerous other parts, indicating the rapid trend toward weight savings by broadening the use of aluminum materials. However, even though great strides have been achieved in weight savings through design, a full market acceptance cannot be realized unless products of stable quality and low manufactured cost can be made available. Discussed herein is the approach being taken by Honda Motor Company to cope with this subject. The focal points to be discussed are the existing production line which produces the large engine cylinder block die casting, and future development of aluminum die casting.
