Apparatus and method whereby coinjection molding shooting pot actuation structure is configured to be installed in a coinjection hot runner with a coinjection nozzle (13), the coinjection nozzle (13) having at least two melt channels (14,15) ending at the same gate (22). The shooting pot is preferably disposed in one of a mold cavity half (11) and a mold core half (10). A shooting pot piston is configured to discharge a melt from the shooting pot. A transmission structure is configured to (i) extend through one of the mold cavity half (11) and the mold core half (10), and (ii) to transmit a force to the shooting pot piston (45). Actuation structure is disposed on the opposite side of the mold cavity half (11) from the coinjection hot runner, and is configured to provide the force to the transmission structure. This configuration conserves space in the mold.
