Provides improved dimensional stability under high temperature conditions up to 80°C. Unlike epoxy boards that may distort beyond 120°C, these polyurethane blocks maintain structural integrity with minimal expansion and contraction.
Ensures uniform heating of complex or large tools and enables quicker autoclave processing compared to alternative materials.
Non-abrasive tooling board that machines with high precision on CNC equipment, delivering superior surface finish and dimensional accuracy.
Tools fabricated with these blocks are significantly lighter than metal alternatives, reducing labor intensity and fabrication time while being ideal for prototypes and small production series.
