I mostly use PU casting resin and have already added some graphite powder in it and worked out perfectly Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com

I would like to make castings for flywheels for example, 4 - 6 in diameter. I tried to cast a 2 inch cube filled with iron powder but it got very hot melting the plastic mould. Any thoughts? Alexanm
