EXACTCASTTM KMV XLHIGHLY EXOTHERMIC AND INSULATINGMINI RISER FOR LARGE CASTINGS
When making molds in large-scale casting, the mold must
be precisely finished, despite or precisely because of its
enormous size, and risers must be placed in the correct
position. In the melting process, large-scale casting
requires a lot of energy to melt the amount of metal. In
quality assurance, defect mediation is crucial, because
small defects in the solidification process of the metal canrender the huge casting unusable.
Developed specifically for large castings, EXACTCASTTM
KMV XL is a cold-box bonded mini-riser with highly
exothermic and insulating properties. Thanks to theperfect balance between both properties, the riser
provides the right performance during the solidification
process of large steel or iron castings. EXACTCASTTM
KMV XL risers are the premium solution for optimizing
feeding systems that increase output in iron or steel
casting applications. By using EXACTCASTTM KMV XL,
the volume of a conventional feeding system can be
reduced, thus the capacity of the foundry can beincreased.

EXACTCASTTM KMV XL for large iron and steel castings
The EXACTCASTTM KMV XL product family has establisheditself as one of the most successful in the large foundry
sector. Specially developed for large iron and steel
components, EXACTCASTTM KMV XL risers are a milestone
in innovative riser system design. With EXACTCASTTM KMV
XL, the total costs of large foundries can be reduced andcompetitiveness significantly increased.
Balance between exothermic and insulating properties
This product‘s success is based on the right balance
between the exothermic energy and theinsulating properties. When using riser systems in largescale casting, longer times for casting and filling as well
as for solidification must be taken into account due to thesizes handled. EXACTCASTTM KMV XL risers deliver heatat the right moment and have good insulating properties tofeed the casting during the solidification process.
In addition, the high quality of the EXACTCASTTM KMV XL
riser ensures that it withstands high temperatures over longfilling times while retaining its original shape.
Riser volume cut in half
Many years of experience have shown that anEXACTCASTTM KMV XL riser with half the feeding volume
can adequately and safely replace traditional fiber riser
systems. This reduces the riser volume by up to 50%,
which, in turn, leads to lower melting requirements andthus improved output.
In addition, the total volume of all selected EXACTCASTTM
KMV XL risers should be at least 20% of the casting
volume. This allows the production of multiple castings ornew castings.
