stress-strain curve

Manufacturing; Plastic injection molding

The curve plotting the applied stress on a test specimen versus the corresponding strain. Stress can be applied through shear, compression, flexure, or tension.

stress relaxation

Manufacturing; Plastic injection molding

The decay of stress at a constant strain.

linear mold shrinkage

Manufacturing; Plastic injection molding

The difference between the size of the part and the size of the mold cavity. Values given are often the average of a range.

shrinkage allowance

Manufacturing; Plastic injection molding

The dimensional allowance which must be made in molds to compensate for shrinkage of the plastic compound on cooling.

screw travel

Manufacturing; Plastic injection molding

The distance the screw travels forward when filling the mold cavity.

underflow

Manufacturing; Plastic injection molding

The dominant flow of two confronting flows, over the other. The lesser flow reverses direction giving poor surface appearance and structural strength. Underflow should be avoided ...

damping

Manufacturing; Plastic injection molding

The effect on a mass that causes decreasing amplitude.
