K factor The coefficient of thermal conductivity. The amount of
heat that passes through a unit cube of material in a given time when
difference in temperature of two faces is 1ºF. Karl Fischer
Titration Test A quantitative means of accurately determining the
moisture level in the pellets as a percentage by weight.
Key Material In a blend of two or more materials, material
whose uniform dispersion is most important to the success of the
operation.
Kinematic Eddy Viscosity Ratio of eddy viscosity to density.
Kinematic Viscosity Ratio of viscosity to density; the unit of
kinematic viscosity is the stoke.
Kinematics Motion of bodies without reference to the forces
producing the motion.
Kirksite High thermal conductivity alloy of aluminum and zinc
used for cast molds.
Knit lines (weld lines) The marks visible on a finished part
made by the meeting of two flow fronts of resin during molding.See Weld
Mark
Knockout bar A bar that holds and actuates ejector pin(s) in
mold. Used to eject molded piece from mold.
Knockout pins (ejector pins) A rod or device for knocking out
a finished part from a mold.
Krebs Units Arbitrary scale used for the comparison of
viscosities. |
