of Warm working
The advantages
over cold working are: 1) forces and
power are higher,2) more intricate
work geometries possible, and 3)
need for annealing may be reduced
.or eliminated
T
F
Blow molding is an important
industrial process for making one-
piece hollow plastic parts with thick
.walls

The result is a mold that can maintain better dimensional control over high production volume. b) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with fine wood chips. They are then compressed with high pressure without baking. c) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with dry clay that do not need heat in order to cure.
