EXACTCASTTM formulations
IN series
	The IN series is an insulating
formula designed for use with all
metals including steel.

EX series
	The EX series is a standard grade
exothermic formulation designed
for use with all ferrous metals. Our
EX sleeves & risers are contain lowfluorine levels.

EXF series
	The EXF series is an exothermic
fluorine-free variation. The eliminationof fluorine allows for easier / lesscomplicated disposal of used sand.
Several additional benefits canbe realized with fluorine-free risers &sleeves: reduction of graphite
degeneration, avoidance of surface
flaws and overall cleaner workplaces.

Breaker edge risers use a loose molded part in the bottom area of the riser along with a corresponding springpin to create a specifically defined breaking point. This, in turn, makes it easier to break off the riser and significantly reduce fettling costs. In fact, in some cases one can completely eliminate the need for finish grinding.
A incorporated cap and loose tube (KMV-CC) prevents against riser particles falling into the mold. Both styles
are available in a fluorine free formulation.

The new EXACTCAST™ KIM insertable mini-riser line was created to service customers looking for options
that didn't come at the expense of high metal usage. The "KIM" accomplishes this by doubling the riser wall
thickness. In addition, by incorporating a conical shape less metal is required to fill the space. Total riser
weight is also of little concern due to the lightness of the refractory material composition. Available in a fluorine
free formulation, with or without a breaker core and with metal neck reduction.
