PCT No. PCT/EP92/00991 Sec. 371 Date Apr. 5, 1994 Sec. 102(e) Date Apr. 5, 1994 PCT Filed May 7, 1992 PCT Pub. No. WO92/20506 PCT Pub. Date Nov. 26, 1992An apparatus and method for producing plastic chip cards and chip card blanks with a wall thickness considerably reduced in certain areas involves first injecting the plastic material into an initial mold space that has no reductions in wall thickness as yet. The distance between certain wall areas of the initial mold space is then reduced to the required reduced measure, displacing the plastic material into adjacent areas of the mold space.
