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 computing apparatus connected to the molding machine; and a controller connected to the computing apparatus. The computing apparatus includes a processor configured to generate a previous orientation distribution of the fibers in the mold cavity based on a molding condition for the molding machine, a rotary diffusional distribution of the fibers based on the previous orientation distribution of the fibers, and an updated orientation distribution of the fibers based on the rotary diffusional distribution of the fibers. 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.
