Abstract : The main driving forces for lightweight materials for the automotive industry and military applications are cost effectiveness, high strength, and wear resistance. Precision Metal Forming (PMF) has developed a new and innovative squeeze-casting process called metal compression forming (MCF). MCF integrates the deceptively simple concept of solidification of metal under direct pressure with closed die forging and low-pressure permanent-mold fill technologies. This hybrid process, therefore, combines the advantages of traditional direct-squeeze casting and low-pressure permanent-mold casting. This report discusses property advantages attained with this process over traditional aluminum casting processes.
