The present apparatus for trimming the edges and for cutting holes into three-dimensional hollow work pieces comprises few components and may be easily modified or retooled for use on molded work pieces of different shapes and sizes. For this purpose, the apparatus comprises a support mold 1 having a shape complementary to the shape of the work piece. The support mold is exchangeable and receives or holds the work piece in a form locking manner. The support mold comprises slots 4 or apertures 6 located where the trimming or cutting is to take place in the work piece. A laser cutting device 20 is arranged for cooperation with the support mold 1 in such a way that a relative motion may be performed between the laser cutting device and the support mold. Thus, the cutting laser beam is effective along the slots and along the edges of an aperture.
