Step 6. Lost wax Casting reproduction using wax injection. 21083

This is the sixth step in the reproduction process I use for making my jewelry. After the molds have been fully de-waxed and tempered in the furnace for 12-24 hrs the molten metal is poured into the molds.

Nice videos.I am trying to cast in aluminum a 1/35 sprocket the size of a quarter. But I am new at this. How can I make the mother mold? Can you tell me how to make this mold out of? The sprocket is for a model tank. But I wanna make this sprocket in metal or aluminum. You can see photos of the sprocket in flickr.com keyword 1/35 metal tiger tank.

@matostruck I use silicone injection molds to make my wax copies that are then cast out into sterling silver... or in your case, aluminum or bronze. The silicone molds are made from a 2 part mix. If you want the name of the supplier for the mold mix and equipment to replicate the part, or if you'd like me to make the parts for you, please send me a private message. Thanks.

I also do not want to buy electric furnace, kiln and vacuum machine etc...

@musicmaneman1 for lost wax casting there are certain machines which are required. There are companies which offer custom casting service and rapid prototyping, but if you want to do it 100% yourself, it's hard to cut out the big things. The mold compound is 'Kerr satin cast 2000' I don't have any experience with drywall mud as a mold compound. The overall quality would probably be lacking. The lost wax process is well suited to making the components you spoke of.

Nice series. One question, what's the advantages and disadvantages of using the vacuum method vs a centrifuge?

[hellotoy21]

@menappi Vacuum is a lot safer and usually more consistent than centrifugal but centrifugal is less expensive to purchase and slightly less expensive to operate typically.

Forgive my ignorance but, why do you sustain the vacuum to the casting table after the metal has been poured already? The metal is solid at that point and the vacuum would have no effect.

Hi, Thanks for the videos. I also used same process to mfg my robot parts after seeing this videos. Actually I used coal furnace but it takes too much time So I'm searching for small electric furnace.

Please give me detail about furnace that you used also It's cost..

Thanks again.

What type of molding compound do you use? I have seen people use drywall mud mix. Is this acceptable? I want to make some aluminum gun parts (scope mounts and muzzle breaks and stuff) and I am crossed between sand casting and lost wax process. Have you ever done sand casting?

What temperature range can you melt at with your machine? I would like to cast some aluminum and was wondering if the machine would be able to melt it. I believe aluminum melts between 1200-1300 f .I prefer to go with a simple small electric setup like yours to melt. How long does it take to melt and what price do they typically run? Thanks
