Mold crater

Fig. 2(a) shows the SEM micrograph wire EDM micro-grooved of stainless steel part. From the micrographs shown in Fig. 3, it is seen clearly that the craters/depressions present on SS surface have been replicated by the polymer parts, indicating a good replication quality. This suggests that the polymer flows easily on the surface when molding was performed at elevated temperatures and ambient pressures. All the four polymers of this study showed the same response.
