Fuel Pump

Part Geometry (as in radii, wall thickness, fillets, parting line...) applies almost identically to diecast molds and plastic injection molds.  If you can build a diecast mold, you can normally build a plastic injection mold and vice versa.

Deicast molds are necessary for parts molded with metals.  The melt temperature of the metal material used in diecast parts is considerably lower than steel.  Aluminum and Magnesium are two common diecast materials.

The Fuel Pump body pictured is for an automotive replacement part manufacturer.  Their was no part development required by St. Joseph Mold and Tool.  The dimensions were availeable and complete, although these dimensions were on old prints.

Our task was to update and get back into production a long-lived product.

The antiquated data needed to be integrated into contemporary diecast moldmaking technology.  This was accomplished by generating a solid model of the fuel pump body using our Solid Works solid modeling seat.

The solid model of the fuel pump body provided the paths for the easy generation of cavity blocks, cam blocks, and cores.  These resulting computer generated components were also in the form of solid models.

The components were CNC milled and then other components and systems installed to bring about the completion of a fully functional diecast mold.
