Plastic injection molding
Plastic injection molding is the primary process for manufacturing plastic parts used in consumer goods such as computer keyboards, monitors, bottle caps, cups and solid plastic articles. Plastic is known to be a very versatile and economical material that is used in many applications. Injection molding involves taking plastic in the form of pellets or granules and heating this material until a melt is obtained. Then the melt is forced into a split-die chamber/mold where it is allowed to "cool" into the desired shape. The mold is then opened and the part is ejected, at which time the cycle is repeated.

Plastic injection molding
Tie-bar spacing
Manufacturing; Plastic injection molding
The space between the horizontal tie-bars on an injection moulding machine. Basically, this measurement limits the size of moulds that can be placed between the tie-bars and into the moulding ...
Ash content
Manufacturing; Plastic injection molding
The solid residue remaining after a substance has been incinerated or heated to a temperature sufficient to drive off all combustible or volatile substances.
Finite element analysis
Manufacturing; Plastic injection molding
The solution of simultaneous equations for each element with resulting pressure, temperature and elapsed time at each node.
Melt strength
Manufacturing; Plastic injection molding
The strength of the plastic while in the molten state. This is a pertinent factor in extrusion, blow moulding and drawing of molten resin from a die.
Yield strength
Manufacturing; Plastic injection molding
The stress at which a material exhibits a specified limiting deviation from the proportionality of stress to strain.
Molecular weight
Manufacturing; Plastic injection molding
The sum of the atomic weights of all atoms in a molecule. Especially in plastics an average molecular weight is reported.
Molecule
Manufacturing; Plastic injection molding
The smallest unit quantity of matter which can exist by itself and retain all of the properties of the original substance.
