Abstract:
A method of fabricating a device having at least two parts molded of different materials, comprising:providing a mold cavity having at least three cavities, a first cavity defining a configuration of a first part of said device, a second cavity defining a configuration of a second part of said device and a third cavity defining a configuration of a third part of said device, said cavities initially being in flow communication with each other with flow communication between said first and third cavities being through said second cavity; temporarily closing off said first and third cavities from said second cavity including closing flow communication between said first and third cavities; injecting a first material into said second cavity to mold the second part of said device; opening flow communication between said first and third cavities; injecting a second material into said first and third cavities, said second material flowing between said first and third cavities through at least one portion of the second part of the device as molded wherein said at least one portion of said second part effectively defines a passageway for said second material between said first and second cavities to form said first and third parts of said device; ejecting said device from the mold cavity whereby said device as molded has parts of different materials molded sequentially together.
