Claim 14:
15. A method for producing a sieve basket for receiving medical items to be disinfected or sterilized, the method comprising the steps of:
producing a base plate from a sheet metal blank, the base plate comprising an inner portion and edge portions;
forming apertures in the inner portion to create a plurality of struts;
processing the base plate to remove warping caused by internal stresses that develop after the step of producing the base plate and/or the step of forming apertures, so that the inner portion and edge portions are flat and conform to a single plane;
bending or deforming the edge portions relative to the inner portion to form a sieve basket shape having a bottom and sidewalls; and
pressing at least one embossing punch onto the inner portion, after the step of processing the base plate to remove warping, to plastically deform the plurality of struts so that each strut assumes a uniform wave shape.
