In order to estimate the process parameters that will allow obtaining an adequate temperature at
the interface, a 32 factorial design was carried out involving only numerical simulations (table 4). Since
the desired temperature at the interface should have lower values than the processing one (the material
temperature during the injection), the proper combination of process parameter can be taken from the
response surface presented in figure 6. A rough estimation indicates a laser power around 16W and a
laser speed about 0.6 m/min.
