For the processing of prepregs in autoclaves we manufacture direct milled tools or CRP moulds. This is depending on the given production volume. The direct milled tools are especially suitable for highly reactive prepregs, which get processed during low temperatures and small pressures. Because no model making is needed, this process is cost effective. However the tools are just appropriate for a small number of pieces. CRP moulds get initially manufactured with the help of milled master moulds. These moulds are robust and durable, moreover they can resist temperatures up to 200°C.
