Tooling / Modelling Board
Polyurethane tooling block or modelling board (different names for the same material) is cut and shaped by hand or, particularly the higher densities, by CNC router to produce dimensionally accurate patterns (or bucks) of a composite part. The filled nature of tooling block means that the shaped pattern can already have a high quality surface finish which needs little surface preparation before it can be used to produce a mould.
Lower density model board is suitable for hand machining and even hand carving (although for quicker easier hand carving of a pattern PU Foam Block is recommended) with the higher density model board being suitable only for hand machining or CNC machining.
Model board is also used by architects and architectural model makers to create accurate, stable models of buildings or architectural landscapes.
Once a pattern has been cut and finished to the desired shape the PU board is compatible with a wide range of finishes and release agents.
