Air Hole : A hole in a molding by air or gas trapped in the melt during solidification.
Air Traps : Converging flow fronts surround and trap a bubble of air or gas which will cause a surface blemish in the part .
Bottom Plate: The plate fixed to the moving half of die and facilitates attachment to the injection molding machine .
Cavity : The mold or die impression that gives a molding its external shape.
Core: Male potion of the mould, which forms internal shape of the component.
Cooling: Channels located within the body of a mold through which a cooling Channels medium is circulated to control the mold surface temperature.
Cycle Time : The time required by an injection molding system to mold a part and return to its original position/state.
Draft : An angle or taper on the surfaces of a pattern or insert that facilitates removal of parts from a mold or die.
Edge gate:Entrance to the part from the runner located on the parting line.
Ejector: A mechanism that pushes the solidified molding out of the die.
Feeding: In a molding, providing plastic melt to a region undergoing solidification, usually at a rate sufficient to fill the mold cavity ahead of the solidification front and to compensate for any shrinkage accompanying solidification.
Flash: A thin section of plastic formed at the parting surface.
Temperature :The material temperature at each point as that point was filled. The result shows the changes in the temperature of the flow front during filling.
Gate: Is a channel or orifice connecting the runner with the impression.
Guide Pillars : Cylindrical members meant to align the mold halves and are & Bushes made of hardened steel. Bushes are meant for wear resistance between housing and pillars.
Hesitation : Hesitation is a surface defect that results from the stagnation of polymer melt flow over a thin-sectioned area, or an area of abrupt thickness variation.
Housing : A metal block which houses inserts (core and cavity), pillars, return pins etc.
Injection: The process of forcing molten melt under pressure into molds.
Injection Location :The injection location is the place where the molten plastic is forced into the mold cavity.
Insert : A part formed from a second material, usually a metal that is placed in the molds and appears as an integral structural part of the final molding.
Locating ring: Is a circular member fitted to top-plate of the mould. Its purpose is to register the mould in its correct position on the injection machine.
Molding: Plastic part molded to the required shape by pouring or injecting melt into a mold, as distinct from one shaped by cutting or a mechanical working process.
Mold Temperature: The temperature at which the mold is maintained. Often the most important benefit of raising mold temperature is that it allows a slower injection rate without the plastic getting too cold.
Nozzle: Hollow metal hose screwed into the extrusion end of the heating cylinder of an injection machine designed to form a seal under pressure between the cylinder and the mold.
Parting Plane : In molding, the dividing plane between mold halves.
Runner: A Channel through which melt flows from one receptacle to another.
Sprue Bush: A bush with a tapered hole, which connects nozzle with runner.
Tie Bar: A bar-shaped connection added to a casting to prevent distortion caused by uneven contraction between two separate members of a casting.
Vent : A small opening or passage that facilitates the escape of gases when the melt is fills the die cavity.
