You can make a "negative" mold easily with RTV silicone. It's flexible, so it's easy to remove the original part and any subsequent castings. If the part has a lot of detail, or is an odd shape, you may need to support the RTV mold with a plaster shell.
Check out some Theatre Prop Building books from your local library, lots of good casting info to be found there.
