  1. Ceramic and band heaters are a bit expensive compared to a wire
    coil heater, but the benefits they offer are great.
    The length-to-diameter ratio, pitch, length of each zone and helix angles of
    a screw must all be matched to the plastic type being
    used. The screw must also be designed to suit a specific type of die.
