摘要： The invention relates to a wall-ironing tool for manufacturing metal containers with a cylindrical body and a bottom by deep drawing, which tool comprises a mandrel and at least one wall-ironing ring unit. Such a wall-ironing tool is known. Known in the prior art is the use of a mandrel and/or a wall-ironing ring of hard-metal. Hard-metal is a comparatively heavy material having a specific mass of 14.000-15.000 kg/m . This results in large inertia forces, particularly for the mandrel reciprocating at great speed. A further drawback of the use of hard-metal is limited acid resistance, whereby the relevant surfaces may not be touched with the fingers and it is necessary to rely on special cooling means with a known pH. The invention proposes a wall-ironing tool of the type stated in the preamble which has the characteristic that the mandrel and/or the or each wall-ironing ring, at least the active surfaces thereof, consist of ceramic material.
