The primary method of molding plastic vehicle components is injection molding. Vacuum is used first to convey plastic pellets into a hopper. The plastic pellets are then heated and forced under high pressure into a mold cavity. The parts are formed in the mold cavity and in some cases vacuum is drawn in the cavity to aid the process and give the products better definition. Finally, after the parts have been formed, they are removed from the mold with suction cups and pumps that are usually attached to a robot arm.
