A flow head and a method for use with a blow molding apparatus. The flow head includes a flow head housing with a material flow cavity. The flow head housing includes a movable die pin mechanism which is moveable between an open position and a closed position. A main melt pipe is connected to the material flow cavity. The main melt pipe is maintained at a first temperature. A shot chamber mechanism is connected to the material flow cavity. The shot chamber mechanism is maintained at a second temperature, which is lower than the first temperature. Thermoplastic material is formed into a parison for the blow molding apparatus. As the movable die pin mechanism is positioned in the closed position, the thermoplastic material is moved to the shot chamber to prevent degradation of the thermoplastic material.
