How it's used
Primarily used in the context of plastic injection molding and hobbyist model building to describe the excess plastic left at the injection point. It refers both to the physical gate on the mold and the resulting scrap piece that must be removed after the part cools. In casual conversation, it is often synonymous with the unwanted plastic nub that remains on a piece after it is detached from the runner.

There are still many gate marks on this model that haven't been trimmed.
Use the side cutters to trim off the gate marks first.

Common mistake
Do not confuse this with the geographical term 水口 which refers to a water outlet or a coastal area. In a workshop or hobby store, the context will make it clear that it refers to plastic molding, but outside of those settings, the meaning changes entirely.
