Polyurethane board sets from Rampf for foundry modeling

With its highly abrasion-resistant Raku Tool WB-1258 foundry board, Rampf is offering an alternative to face cast pattern plates and highpriced metals for a wide range of foundry modeling applications. Thanks to its very good abrasion resistance, more than 100,000 replications can be produced with the PU board. This was previously possible only by using either liquid systems with complex manufacturing processes with higher costs or high-priced metals like aluminium, said the company.

With the new foundry board material, core boxes and pattern plates are manufactured that facilitate the quick and easy production of models with outstanding abrasion resistance, dimensional stability and accuracy.

The core box/pattern plate is directly milled using CAD data, which also ensures the high precision of the models. The dimensionally stable polyurethane board is easy to process and changes can be easily made. The product also exhibits minimal sand adhesion, high chemical resistance, and virtually no swelling. Milling tools made from this board have significantly longer service life. Colour-matched adhesives are available.
