Intrested in learning

[DeadPerson]

Hello, Im a CNC machinist working in a faucet company. So far I've been doing moderate production and modifying current parts, and I also do prototypes. Now that time has gone by, the prototypes they request now get more complex and difficult to machine in a CNC Mill and lathe.

So i am intrested in learning the entire process in making a mold and casting it, but I dont know where to begin, and what materials I need to start. Can anyone help me?

Are you talking about a model.....or a real mold.....For a mold, you still need the ability to create a 3D model...1/2 will be machined into a piece of steel or aluminum to create a negative image...same goes for the other side.....

If we talking faucets...then you still need a model that you can use to create a cavity in the sand molds that will be used to cast the part.....you will need to learn about casting sand (Petrobond), flues, gates, etc.

What you just said is exactly what I need. I know how to use Mastercam X (taking a class atm) and they gave us a example on how to make a cavity, and I'll prolly end up buying Mike Mattera's videos if I ever need MCX refrence.

What I need now is how to make a mold, what materials you need, what are the formulas, all the works ( i know im talking about 10 years worth of info). Are there any books out there to help me get started on this?

Here's one link with many links...also search the Internet for "sand casting", mold making, lost foam casting....

Also...when you make metal molds....they are generally used for casting plastics.....

Sand casting or lost foam casting is the pretty traditional method for making metal castings with the exception of those metals with low casting temperatures....like the white metals which can be centrifically cast in a silicone rubber mold....
