1001 opportunities with polyurethane

During October 2011 the two millionth board was produced at Rampf Tooling. This is a further milestone in the success story of the RAMPF Group which meanwhile comprises five independent companies with a consolidated turnover of Euro 104.4 Mio and three overseas subsidiaries.

The success story started 32 years ago.

1980 the modeling material in the automotive industry was still wood - the problem - wood is not dimensionally stable.  A new material had to be sought and was found in polyurethane. The first board made in polyurethane (was produced in an old factory in Renningen, South Germany. Two years later, with the market penetration of the first "PUR-board" for modeling, the first production line was built up.  In 1987 the first styling board was produced and in 1994 the first working board for jigs was developed and manufactured in Grafenberg (near Stuttgart). 1998 marked another milestone: Rampf Tooling developed the first modeling board made from recycling polyol. With this invention Rampf Tooling has taken a new step in the direction of a „greener" future. In 2006 Rampf Tooling decided to enter the market directly and succeeded in becoming the largest board producer world-wide under the brand name Raku-Tool. The produced boards have a smooth and uniform density. Today, the well-balanced product portfolio of boards comprises a total of 37 different products including some boards made from recycling polyol.

With the consistent trend towards CAD/CAM Rampf Tooling continues to develop its quality board materials. Excellent, fine surface structures, improved machinability and chip formation, high mechanical properties as well as matched bonding and repair systems are all part of the world market leader's service spectrum.

The service offer, customized products, is constantly expanded. Most board materials can be ordered in any size and can be adapted to meet the customer's special needs and applications.

In this way Rampf Tooling supplies ready to machine castings and blocks and even customized large volume size castings of up to 10 tons. The customer can therefore fully concentrate on his strength, the machining of the casting or block.

"To date we have cast 110 million tons of material, delivered 400 containers and produced 2000 boards per week," explains Heinz Horbanski, Managing Director of Rampf Tooling. "We consume 50 percent of the PU production of Rampf Giessharze for our own board production, which equals around 40-50 tons per week."

Among many examples in the automotive and aircraft industry (e.g. protective caps for the wings of the A380) we would like to introduce some special applications:

At the Technology fair in Yokohama he presented a black panther made with Raku-Tool SB-0080, a symbol of the African-American Civil Rights Movement in the United States and a life-size version of „Nats-chan", a popular, Japanese comic girl, made of  Raku-Tool SB-0470. "Comics have a long tradition in Japan and the message is well understood in his country. Japanese comics are unique in terms of design and the techniques used by their creators," explained Midorikawa the reason for this special application. "The models are excellent examples of what is possible with model and prototype construction."

The wood sculptor Samy Virmoux has designed a sculpture with Raku-Tool SB-0470(Photo r.), after discovering polyurethane as a possible material. Born 1964 in La Faute sur Mer, France he visited l‘Ecole des Beaux Arts in Nantes. Since 1995 the professional book restorer works freelance. Virmoux's usually impressive oak wood sculptures, timelessly elude all standard stylistic classification trials. He lives in South Germany.
