Tool made from plastic
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.
