The reduction of the SCORIM cycle time is evident with the increase of the filler concentration, being the result of the HA loading, since the ceramic amount determines the thermal conductivity of the compound.
Nevertheless, the severe thermo-mechanical conditions imposed in injection molding, especially during SCORIM application (melt temperatures close to 200[degrees]C).
t] for SEVA-C/HA composites as a function of the HA weight percent for both conventional injection molding and SCORIM (best mechanical results following a maximum stiffness criteria).
HA composites, the higher stiffness of SCORIM moldings is distinguishable for 30 and 50% wt.
t] and UTS for conventional and SCORIM moldings of the 30% wt.
HA SCORIM processed composite, it was possible to produce samples with [E.
The injection of material into the Cavity is again followed rapidly by the application of SCORIM periodic shears to orient alignable materials.
Moldings were produced using the three different cavity geometries and the four inJection molding techniques, namely conventional, BSM, SCORIM, and SBM.
Weld line removal for this material was investigated using BSM and then using SCORIM as photographed in Figs.
Figure 11 shows these moldings made conventionally, with BSM, SCORIM, and SBM.
At 25 [degrees] the conventional and SCORIM moldings show similar high values of reflectivity comparable to those of a good sprayed metallic paint, e.
The application of SCORIM appears to alter the intensity of reflectivity slightly over that of a conventional molding.
