Gasket
A static (stationary) sealing device used to retain fluids under pressure or to seal out foreign matter
Gate
In injection and transfer molding, the orifice through which the melt enters the cavity. Sometimes the gate has the same cross-section as the runner leading to it; often, it is severely restricted
Gate Edge
A gate that is cut along one edge of the mold cavity
Gate Fan
Large cross sectional area for feeding plastic into the cavity. Flow channel tapered from the runner to the gate
Gate Flash
A gate that encompasses entire periphery of part. Usually of low sectional thickness in relation to part
Gate Mark
A raised spot or small depression on the surface of an injection or transfer molded part where the gates interface the cavity. See also Sprue Mark
Gate Pin-Point
A restricted orifice, usually used in a three plate-type mold, through which molten resin flows into a mold cavity
Gate Ring
The clearance between the force plug and the vertical wall of the cavity in a positive or semi-positive mold; also the ring of excess material which escapes from the cavity into this clearance space
Gate Sprue
The type of gate in which the plastic is injected directly from the molding press into the cavity
Gate Straight-in
the rectangular area between the runner and the part. This area is tapered on three sides so the smallest area is at the point of contact with the part
Gate Underside
The orifice found between the "A" and "B" plate which carries the resin into the cavity in an overlap of the part in such a manner so as to obtain a clean break on the part. Usually found in thermoset molding
Gates
the openings in an injection or transfer mold whereby material enters the mold cavity
