Abstract: A method of forming a component of a vehicle heating, ventilation, and air-conditioning system from polymeric material includes providing a molding system including at least one mold cavity defining the component. A base resin is introduced to the mold system via an inlet. A chemical foaming agent is blended with the base resin to form a composition. The composition is then further heated and blended under pressure, wherein the chemical foaming agent decomposes within the composition. The composition is introduced to the mold cavity, wherein a reduced minimized pressure of the mold cavity facilitates initiation of a nucleation of the composition, wherein the composition expands to fill the mold cavity.
