Abstract:
A method of forming a fluid meter housing, comprising the steps of:providing a first mold having an internal surface corresponding to the internal shape of a fluid meter housing; injecting molten metal into said first mold; cooling said first mold and molten metal until the metal solidifies forming a metal core shaped like the internal surface of the fluid meter housing; removing said metal core from said first mold; providing a second mold having an internal surface corresponding to the external shape of the fluid meter housing, said core and said second mold configured for creating a cavity in the shape of the fluid meter housing; placing said metal core into the second mold so as to create said cavity; injecting into said cavity a molten thermoplastic to fill the cavity formed between said metal core and said second mold; cooling said second mold until the molten thermoplastic is solidified thereby forming the fluid meter housing; removing from said second mold the fluid meter housing containing said metal core from said second mold; heating the plastic fluid meter housing and metal core until the metal becomes molten; and removing the molten metal from the fluid meter housing; wherein said first and second molds are further formed for providing a plurality of tabs and a locking boss on said fluid meter housing for detachable connection of a register.
