Abstract
Methods for manufacturing components capable of transporting a liquid including providing a mold, placing at least one core made from a core material into the mold, injecting a component material into the mold about the core to produce a green component, heating the green component to burn out the core and produce a brown component, and sintering the brown component to produce a finished component capable of transporting a liquid wherein the finished component is from about 95% to about 99% dense.
Claims20
A method for manufacturing components capable of transporting a liquid comprising:
- providing a mold;
- placing at least one core made from a core material into the mold;
- injecting a component material into the mold about the core to produce a green component;
- heating the green component to burn out the core and produce a brown component having at least on cavity therein;
- and
- sintering the brown component to produce a finished component capable of transporting a liquid through the at least one cavity wherein the finished component is from about 95% to about 99% dense.
A method for manufacturing components capable of transporting a liquid comprising:
- providing a mold;
- placing at least one core made from a core material into the mold;
- injecting a component material into the mold about the core to produce a green component;
- heating the green component to burn out the core and produce a brown component having at least one cavity therein;
- sintering the brown component to produce a finished component capable of transporting a liquid through the at least one cavity;
- and
- hipping the finished component to produce a densified component that is about 99.9% dense.
A method for manufacturing components capable of transporting a liquid comprising:
- providing a mold;
- placing multiple non-linear cores made from a core material selected from the group consisting of SLA-type resins, polycarbonates, polypropylene, and combinations thereof, into the mold;
- injecting a component material selected from the group consisting of nickel based alloys, cobalt based alloys, and combinations thereof, into the mold about the cores to produce a green component;
- heating the green component over a temperature range of from about 150° F. (about 65° C.) to about 500° F. (about 260° C.) to burn out the core and produce a brown component having multiple non-linear cavities therein;
- and
- sintering the brown component over a temperature range of from about 700° F. (about 370° C.) to about 2300° F. (about 1260° C.) to produce a finished component capable of transporting a liquid jet fuel through the cavities wherein the finished component is a fuel nozzle comprising a fuel conduit supply and a fuel distributor ring and wherein the finished component is from about 95% to about 99% dense.
