Lightweight construction solutions for the aerospace industry

Rampf Tooling, a producer of liquid, paste, close contour, and board materials for model and mould making, will present its products for lightweight construction with a focus on the aerospace industry at JEC Europe from 12 – 14 March 2013 in Paris. The company will highlight its Raku-Tool product range, which comprises epoxy and PU systems used in composites production processes, like hand/wet lay-up, vacuum bagging, resin infusion, prepreg, autoclave, wet compression moulding or RTM, and cover a wide application temperature range.

Included will be the close contour casting material Raku-Tool CC-6503, which can be used for the production of lay-up tools as it exhibits a good and seamless surface structure. The materials are supplied as ready to machine, three dimensional castings, already a close outline of the final shape. The close contour products which can be used for mould and tool production feature a fine, seamless surface, good machinability, no handling of liquid materials to the greatest possible extent and a good dimensional stability, says the company. Due to the already close contour shape, less waste is generated, so the final shape can be milled faster and with less cutter wear.

The new working board, Raku-Tool WB-0691, together with adhesive and repair paste will be presented as a complete package solution. Its application area stretches from lay-up tools for low temperature prepregs and vacuum forming tools to applications in the medium temperature range in racing, marine, sport, medical technology as well as the machine industry. A case study showing the production of a gangplank for a yacht using the classic and proven Raku-Tool WB-0700 will be on show.

From the range of liquid systems, the company will showcase the epoxy infusion system EI-2500/EH-2970-1, which is used to impregnate dry fibre packages in one operation and exhibits good flow and wetting properties. Through the resin infusion process a high part quality with low part thickness variance as well as high mechanical properties can be achieved. Additionally structural changes are easily possible, says the company.

In addition, Rampf Giessharze and Rampf Dosiertechnik will exhibit customised components for sealing, bonding, casting and coating as well as low pressure mixing and dispensing machines. One display will be the C-DS-Tooling, a mobile, compact and adaptable dispensing machine for manual casting of parts.
