Board Materials
for Styling, Model Making and Tooling – Mill. Done.

For over 40 years, we have been developing innovative Board Materials for model making, mold making and tooling – engineered in Germany. Our RAKU® TOOL solutions deliver efficiency, performance, and sustainability: densities from 0.08–1.7 g/cm³, fine surface quality, high dimensional stability, easy machining, plus perfectly matched adhesives and repair fillers. Through closed-loop recycling, we reuse up to 50 percent of production residues; our systems contain up to 30 percent chemically recycled components. Tooling and Modeling – efficient, powerful, sustainable.
Properties and Functions
- Styling Board Materials (SB) – lightweight, precise, easy to machine: PU semi-finished products with extremely fine surface structure. Ideal for negative molds for casting, substructures for pastes, CNC test runs, design and form studies, styling, master and data control models, and negative molds. Apricot-colored versions available. Excellent manual and CNC machinability.
- Model Making Board Materials (MB) – dimensional stability for masters and presentation models: PU model making boards with clean chip formation, stable geometry and homogeneous surfaces. Density range 0.6–0.72 g/cm³. Perfect for master models, cubing and presentation models, design and form studies; adhesives matched in color and hardness.
- Tooling Board Materials (WB) – epoxy and PU for demanding applications: density ranges 0.69–1.7 g/cm³, high dimensional stability, fast CNC machining. Ideal for metal forming, hammer tools, foundry tooling, molds, jigs, and layup tools. Our epoxy variants are the benchmark for layup tools in composites (prepreg), proven in automotive and aerospace.
- Adhesives – perfectly matched: 1-component and 2-component systems based on epoxy and PU. Excellent adhesion, flow behavior, easy machining, fast room-temperature cure. Precisely matched to the color and hardness of each polyurethane tooling board.
- Repair Filler – fast restoration: 2-component epoxy fillers, with properties and color perfectly aligned to the corresponding materials. Easy to machine, fast curing; hardener also available separately and compatible with standard Board Material adhesive resins.
