Barrel machine component where resin is fed into for heating and mixing; contains the screw
Cavity hollow half of the mold; typically referenced as the A-side
Clamping Force force needed to keep mold closed while mold fills with plastic
Cold Runner channels in the mold that flow material to the part cavity; hardens with part and is removed after ejection
Cooling Channels channels built throughout the mold to control the mold temperature
Core half of the mold that fills the hollow side; typically referenced as the B-side
Cycle Time time it takes to complete one molded part; commonly measured from mold open to next mold open
Ejector Pins installed in the mold to eject the part from the mold when properly cooled
Flash excess material on molded par
Gate entry point for plastic into part cavity
Hot Manifold channel system that runs material to the part cavity and keeps material heated to avoid a runner
Knit Line occurs where different flow fronts of material meet while flowing through the mold
Mold Flow Analysis computer simulation of predicted material flow, fill, and warp in mold to assist in tool and part design
