Molding system for preparing molding article

A molding system for preparing an molding article, comprising:

• a molding machine;
• a mold disposed on the molding machine and having a mold cavity for being filled with a molding resin;
• a processing module configured to generate a mechanical pressure distribution of the molding resin in the mold cavity based on a molding condition for the molding machine, wherein the mechanical pressure distribution of the molding resin is generated based in part on a bulk viscosity effect of the molding resin;
• and
• a controller operably communicating with the processing module and configured to operate the molding machine for transferring the fluid molding material into the mold cavity with the molding condition using the generated pressure distribution of the molding resin to perform an actual molding process for preparing the molding article;
• wherein the mechanical pressure distribution of the molding resin is generated based in part on the bulk viscosity effect to a volume variation of the molding resin.
