The authors (17) also studied the effect of ISBM process parameters and preform design on the bottle properties; the process parameters comprising the blow pressure, the timing of the blow pressure activation relative to the stretch rod motion was studied to improve the simulation predictions of bottle wall thickness (18), (19).

Experimental study of preform reheat temperature in two-stage injection stretch blow molding

The optimal conditions are rear temperature of 320 (degrees)F, front temperature of 300 (degrees)F, block temperature of 300 (degrees)F, injection pressure of 1000 psi, blow pressure of 60 psi, mold temperature of 120 (degrees)F, and mold close time of 60 seconds.

Therefore the preblow pressure is applied shortly after the end of preform stretching quickly followed by the final blow pressure, since there is no risk for the rod to contact the preform wall in that situation.
