Grafenberg, Germany -- Many pattern makers attended a foundry symposium focussing on current industry topics and on RAMPF Tooling's solutions and products, hosted by Rampf and partner Esterhammer at Rampf's new innovation centre in Grafenberg at the end of June.
To be able to compete with the international industry, Germany's foundry industry must use new and trend-setting products, Rampf points out: "Pattern makers want innovative solutions."
During the event, RAMPF Tooling's team demonstrated various chemical and abrasion tests and showed how to evaluate the results. Such tests are especially important for model making in the foundry industry, the company emphasises.
In its new innovation centre's technical school, the team then demonstrated various Raku-Tool liquid systems, including a key product, the gelcoat PG-3104. Ramp says this exhibits "excellent impact strength and is suitable for large-series production."
The experts also showed the PC-3451 casting system "which has no skull and crossbones label and is also suitable for large-series production," Rampf noted. Many different models were produced from various abrasion-resistant polyurea gelcoats and face-casting systems as well as from the polyurethane fastcast, full casting and epoxy systems, the company said.
Raku-Toolboard materials come in different qualities, mainly for model production. With Raku-ToolWB-1250, delegates saw first hand during a milling demonstration the good chip and low dust formation with this material. Rampf also showed the "eco board" Raku-ToolWB-1450, produced using predominantly recycled polyol.
Rampf also showed its Close Contour Casting process, a technology which it says gives quicker machining, less tool wear and less wastage. Models or moulds are made using special mix and metering equipment and RAMPF's own casting technology.
Guests had the opportunity to ask detailed questions: "I think it is great to obtain first hand information on new products but I also appreciate the opportunity to talk to colleagues from the industry" commented one of the participants.
Peter Eggelbusch and Stefan Hauk from CLAASGUSS were in search of new solutions. "We are already using a Raku-Toolboard material with a very good dimensional stability for the production of foundry patterns and core boxes and we will shortly test another board material."
Rampf said company founder Rudolf Rampf "revolutionised the modeling market in 1981 with the invention of the first polyurethane board." Today the company offers a wide range of model, mould, and tool-making materials under the Raku-Tool brand.
The products are used in many industries such as automotive, aerospace, marine, wind energy, ceramics, plastics and mechanical engineering. The material specialist also has a worldwide presence through the American and Japanese subsidiaries of RAMPF Group, as well as via numerous distributors throughout Europe.
