Freeman Manufacturing & Supply Co. (Avon, Ohio) is featuring its line of modeling and tooling boards. The newest addition is RenShape 5065, a high-performance, high-temperature epoxy board developed for use at temperatures up to 400°F/204°C in applications such as aerospace master models and layup tools for high-temperature-curing prepregs. It is reportedly able to maintain dimensional stability at high temperatures and is a suitable substitute for metallic materials. This board offers good edge definition and good surface finish with a Tg of 470°F/243°C. RenShape 5065 machines cleanly on the CNC by producing chips instead of dust.
