This paper investigates volumetric shrinkage phenomena occurring during the injection molding process of polymer materials and its influence on product quality. The study focuses on a washing machine tank manufactured from PP J-360 material. The effects of cooling system design and heat transfer conditions on volumetric shrinkage are analyzed both theoretically and experimentally. A mathematical model for evaluating volumetric shrinkage is developed based on temperature distribution, pressure variation, and pvT characteristics of the material. Different cooling channel configurations are compared to determine their influence on shrinkage and deformation behavior.
