Abstract: An apparatus is provided that includes a mold that includes a first cavity defining a toothbrush body, a first injection unit in fluid communication with the first cavity and a second cavity, and a second injection unit also in fluid communication with the first cavity. An apparatus is also provided that includes a mold that includes a first cavity defining a toothbrush body, a second cavity defining a toothbrush body, where the first cavity and the second cavity define substantially identical toothbrush bodies, a first injection unit in fluid communication with the first cavity and a second injection unit incapable of being in fluid communication with the second cavity.

Abstract: An injection molding system includes a first unit that has a first injection molding machine configured to inject a first molding material into a first cavity partitioned by a first fixed mold and a movable mold, a second unit that includes a second injection molding machine configured to inject a second molding material into a second cavity partitioned by a second fixed mold and the movable mold, and a movement mechanism configured to, after the first molding material is injected into the first cavity, move the movable mold filled with the first molding material from the first injection molding machine to the second injection molding machine.
