A blow molding machine comprising a base, a wheel mounted rotationally on the base, a controller to control operation of a pin within a die, and a position detector for detecting a short run mold on the wheel wherein the wheel comprises a plurality of identical molds and the short run mold which differs in size and/or shape fr om each of the plurality of identical molds. The position detector, upon detecting the short run mold, switches a relay to switch from a first pin control program causing th e extrusion of a parison having; appropriate parameters for the plurality of identical molds, to a second pin control program causing the extrusion of a parison having appropriate parameters for the short run mold.
