| Summary: | Sidecore is a dies component of molding on low pressure die casting. The material
used to Sidecore is FCD 500, which has the basic micro structure of ferrite -
pearlite. Problems that occur in the foundry process is not achieving basic form
microstructure ferrite - pearlite, but tend ferrite. Of the failure modes, designed
tackled by giving of promote perlite elements in the smelting process. One of the
promote pearlite elements is copper.
Research starts from the planning and designing of the casting process by varying
the composition of Copper 0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6%. Then proceed with the
manufacture of foundry patterns and test samples according to the design. Once the
sample is finished, metallographic microstructure testing, hardness testing, and
tensile testing.
The result of this research had been concluded that: the addition of 0.2% copper
influenced to producing of nodular cast iron FCD 500 with microstructure (48%
ferrite - 52% pearlite) on 25mm walled casting thickness. |
