AbstractThe subject invention provides a method of manufacturing an air conditioning compressor assembly for a vehicle having a front head member. A forming die having a cover half and an ejector half is shaped to define the features of the front head member. A conventional casting process is used to form the front head member. The front head member is cast to include a plurality of sealing surfaces, each concentric with a bore. A fastener passes through the bore to secure the front head member to the compressor housing such that a head portion of the fastener is in sealing engagement with the sealing surface as cast into the front head member to provide a pressure tight seal therebetween.
