Abstract: The invention relates to a tool consisting at least partially of plastic material and containing nanoparticles which are included into said plastic material. Said tools exhibiting a high pressure and friction resistance, are used in particular as shaping tools, for example for deep drawing of metallic sheets for vehicle bodies.

Abstract: The invention relates to tools (11, 12), made from plastic and a material with slide bearing properties inlaid in the plastic, whereby the plastic tools further comprise a component of inlaid aluminium. Said plastic tools are suitable for the moulding, in particular the deep-drawing of metallic workpieces (10), such as for example components of automobiles. The tools have a high pressure-resistance and wear resistance and permit deep-drawing with essentially small amounts of, or no, lubricants as a result of said slide bearing properties.

Abstract: The invention relates to a tool comprising a partial region made from plastic, in which a material with slide bearing properties is inlaid. Said tool is a moulding tool, which can be applied, for example, in the deep-drawing of metal pieces. The partial region in which the material with slide bearing properties, for example graphite, is inlaid, is a front layer (11) of the tool, comprising the moulding region thereof. The backing (12) of the tool is also made from plastic, which can optionally contain conventional fillers. The front layer (11) of the tool, reinforced, for example, with graphite, permits a deep drawing optionally without the use of lubricants, whereby the moulding region of the tool has good slide bearing properties and a high pressure resistance.

Abstract: The invention relates to a method for producing models or pre-forms, comprising the following method steps: (a) producing a shaped core from a water-soluble block material, (b) coating the shaped core with a curable polymer, (c) curing the curable polymer at from 25 to 250° C., and (d) removing the core material by treating the coated core with water.

Abstract: The present invention relates to compositions comprising A composition comprising (a) a resin containing a polyepoxide and a polyisocyanate, and (b) a treated filler which is either a silane-treated filler or an atomised filler, The compositions are suitable for the fabrication of high performance resin molds which can then be used for various molding methods such as injection molding, press molding, vacuum molding, high pressure molding or foaming molding.
