PROSES SEMISOLID FORMING

Abstract

This paper presents a semisolid forming process as a new process that can replace conventional casting and
forming process. Semisolid forming process is metal procesing in semisolid state. There are several advantages of this
process. The important of these is non-turbulent filling of the die. Non-turbulent die fill in the process can eliminate air
entrapment encountered in the conventional die casting. The semisolid forming process also offers the near net shape
capabilities of die casting and produces parts with less shrinkage porosity and macrosegregation. The limitation of
semisolid forming process is this process requires globular (non-dendritic) structure alloys for raw material process.
