ABSTRACT:
An adapter block having fluid channels is made up of at least two parts bonded together. At least one of the parts is made up of an integral skin foam material, more specially polyurethane. A foam-molded core of this material is covered over by an integrally molded, unfoamed skin. At the faces that are to be bonded the skin is first machined away by a roughening tool. A mold for producing the adapter block is made up of two mold end parts with hollows to take up mold pins so that mold pins or stoppers may be put therein. The mold end part opposite to the end part with the pins is made of an elastically soft material. The mold pins may have concave end faces.
