Rampf: Presentation of modeling board and close contour portfolio
Rampf Group, Inc. has presented its new sculpting epoxy Raku EP-2346/EH-2946 at IAAPA 2021 in Orlando, FL, USA, from 16 – 19 November 2021. The hand-modeling paste ensures unprecedented levels of detail and is very easy to sculpt and process, said the company.

Raku EP-2346/EH-2946 exhibits good adhesion to wood, metal, and fiberglass. The lightweight sculpting epoxy guarantees smooth textures and is classified according to ASTM E84 Class A standard for flame spread and smoke generation. An impressive example of the sculpting epoxy’s qualities was presented at the trade show – a cuckoo clock featuring an extremely high level of detail and perfect finish. The stylish time keeper was made by the design & tooling specialist Weber Group based in Sellersburg, IN, USA.
Rampf said its portfolio of advanced customised liquid polyurethanes and epoxy systems for theme park and specialty tooling solutions is tailored to meet the specific requirements of customers throughout the entire production chain – from prototyping, model, mold, and tool construction to production. The mercury-free and RoHS-compliant systems feature outstanding consistency and quality as well as a wide range of handling, curing, and performance properties.
Rampf also featured its board materials and close contour product range for cost-effective and high-quality model, mold, and tool construction. The tooling boards made from polyurethane and epoxy exhibit outstanding mechanical properties, finest surface structures, and good dimensional stability. The boards are said to be easy and quick to machine and compatible with all industry-standard paints, release agents, and epoxy prepregs. Raku Tool adhesives matched in hardness and color are available.
Rampf boards are used, amongst others, for the manufacture of styling, master, cubing, and presentation models, negative molds for casting, design and form studies, and lay-up tools. (Source: Rampf)
Close contour materials include close contour pastes (two-component epoxy systems which are applied to a close contour substructure by hand or CNC machine), close contour castings (semi-finished polyurethane products supplied as three-dimensional castings that are already close to the final contour), and close contour blocks (polyurethane or epoxy systems which are produced to customer specifications and delivered as unmachined rectangular blocks).
