The Remet FastForm® range of paste injectable waxes were designed to set up rapidly and are ideally suited for increasing productivity when injecting large patterns such as those found in precision investment cast pumps and valve bodies used in oil and gas industries. Initial results of DOE studies carried out with an MPI wax injector showed a marked decrease in cycle time while maintaining dimensional and surface finish quality comparable to standard wax. Establishing acceptable injection parameters for each wax injector often requires large number of samples to be injected. Thermophysical instrumentation offers methods independent of injection machine for characterizing these parameters. Differential scanning calorimetry (DSC) has been used to examine the crystallization and solidifcation of wax and wax components. DMA (Dynamic Mechanical Analysis) has been used to characterize solid shrinkage of wax. We have previously reported on the potential for controlled stress rheometry (CSR) and DMA as investigative tools to look at the viscoelastic properties of waxes across the solid/liquid phase boundary. These investigative approaches were correlated with results obtained with the MPI injector. This composite approach permits a potential user of pattern waxes such as FastForm® to quickly establish injection parameters from a reduced number of test injections.
