6 types of injection molding gate & when to use them

2021-2-24 · The injected molten plastic solidifies inside the mold cavity to form the part, but plastic also solidifies at the gate, which leaves a solid protrusion sticking out of the part. The gate must therefore be trimmed a process called degating either automatically (by the injection molding machine) or manually once the part has been ejected.
