A small gate, generally 0.75mm or less in diameter.
To fill all cavities at the same time in multi-cavity molds, the dimensions of pinpoint gates must be held within tight tolerances . Pinpoint gates leave only a small, easily removed mark on the part. But the melt tends to freeze earlier and a third plate is often required for part removal. Pinpoints gates can also lead to high shear rate and high entrance pressure loss.
An indirect gate is a variant of a pinpoint gate. Indirect gates are used when the injection location must be transferred from the center of the part.
