Force plug

The clearance between the force plug and the vertical wall of the cavity in a positive or semipositive mold. Also the ring of excess material that escapes from the cavity into this clearance space. 

Force plate n. The plate that carries the plunger or force plug of a mold and the guide pins or bushings. Since the force plate is usually drilled for steam or water lines, it is sometimes called the steam plate. 

Force plug (plunger, piston) n. The portion of a mold that enters the cavity block and exerts pressure on the molding compound, designated as the top force or bottom force by position in the assembly. 

Stripper plate In molding, a plate that strips a molded piece from core pins or a force plug. The plate is actuated by opening the mold. 

Figure S.7 Cross section of a split cavity mold for producing a molded spool. A and B form the two halves of the cavity. Chase, C, folds the halves together. Other parts are D, core pin E bottom plate and F, the force plug or plunger. (Ref Buckleitner, E.V., ed., Basic Mold Types and Features , Plastics Mold Engineering Handbook, S " ed.. Chapman Hall, New YotIc)...

Phaser. A ram or piston used for the displacement of fluid or semifluid materials in injection- or extrusion-molding methods also called piston, pommel, force, force plug, and pot plunger. 

Plunger plon-jori n (1611) The part of a transfer-press or old-style injection machine that applies pressure on the unmelted plastic material to push it into the chamber, which in turn displaces the plastic melt in front of it, forcing it through the nozzle and into the mold. See also Ram, Force Plug, and Pot Plunger.
