ABSTRACT:
An adapter block having connection openings provided in and extending normal to a surface thereof is produced by a process which includes the steps of foaming a resin compound such as a polyurethane in a mold cavity which has a shape complementary to the adapter block, the resulting component having an integral skin on the exterior surfaces thereof; then allowing the component to harden; then machining the integral skin off the mentioned surface and a surface on the opposite side of the component; and then applying an adhesive to and placing further components against the machined surfaces so that the further components become secured to the first-mentioned component.
