Epoxy Fixtures are used mostly by stampers who must contend with short runs or
complex shapes. These fixtures usually are cast directly from the part to be stamped
and the back is either sanded or milled flat. They are also used to match irregular
surfaces or contours. Epoxy fixtures require continuous 'make-ready' throughout the
production run because they continually flatten due to the pressure and heat exerted 
by the die. The term 'make-ready' refers to the use of tape, cork, rubber or other
materials to build up depressed areas of the fixture to properly support the part when
die pressure is exerted.
