Low Pressure Permanent Mold (LPPM) Process for Aluminum Suspension Castings 1999-01-0040
Passenger car suspension components have traditionally been manufactured from ductile iron castings or welded steel fabrications. Although, as fuel economy and emission concerns become more important, passenger car component designers are looking to aluminum suspension components for a reduction in unsprung weight. The advancements in the Low Pressure Permanent Mold (LPPM) Casting Process has made it one of the most cost and quality effective methods for producing production quantities of premium grade aluminum castings for the suspension component industry.
This paper presents the advantages, the weight savings potential, the physical and mechanical property data that categorizes low-pressure casting as a state of the art premium grade casting process. The expected conclusion from this paper is that the automotive designers will become aware of the advantages and feasibility of replacing ferrous suspension components for passenger cars with cast aluminum A356-T6 suspension components using the Low Pressure Permanent Mold Casting Process.
