Abstract
A molding system includes a mold having a mold cavity; a molding machine configured to fill the mold cavity with a composite molding resin including a polymeric material having a plurality of fibers; a processing module connected to the molding machine; and a controller connected to the computing apparatus. The processing module includes a processor configured to generate an orientation distribution of the fibers in the mold cavity based on a molding condition for the molding machine, wherein the orientation distribution is generated taking into consideration a combined effect of a molding pressure and a shear rate on a zero-shear-rate viscosity of the composite molding material. The controller is configured to control the molding machine to perform an actual molding with the molding condition for injecting the composite molding resin into at least a portion of the mold cavity.
