    back pressure ?
    suction back?
    humidity - ok.. it is HDPE
    what about RSP? works OK?
    Melt temperature vs. injection speed vs. pressures ?

    Possibly broke or damaged NRV on press. How consistent is shot weight, cushion, peak pressure of injection, or does the screw rotate when injecting?
