    Short shot – The mold doesn’t fill completely and the part is incomplete
    Splay – visible gray or silver streaks on the finished product caused by excess moisture in the material
    Weld line – a line or seam that forms where liquid material comes together
    Burning – Burn marks on the product caused by air trapped in the mold
