I use this for casting aluminum ingots and it works great!
When I first started melting aluminum I tried using a cheap steel muffin pan but I had a very difficult time getting the metal out, I then moved on to a lost foam system which worked, but the result wasn't very clean ( due to jagged edges of the foam, sand impurities, etc. ).
After a short time browsing amazon I came across this mold ( 85x45x30mm size ) and figured I'd give it a shot. To be honest I was impressed with the packaging, but was a little disappointed when it arrived and I saw how small it was ( Tip: measure a piece of paper and cut it to the dimensions you are looking at before you buy, that way you can see how big something is ).
All of my disappointment vanished when I used it the first time and saw how clean the result was, it left a smooth and shiny surface, much better than the foam cut with a knife and came out extremely easily compared to the muffin pan.
Tips:
- The mold gets very hot, don't try to touch it while it's cooling, even with gloves on! ( Not like I would ever do that.... )
- Heat the mold before casting, I personally just set the mold on the lid of my furnace a minute or two before I'm ready to pour. My furnace is currently a carbon furnace but I have yet to see any damage to it. ( I wouldn't use it as a crucible in the furnace though )
Photo Description:
The stack in the back is the ingots I've cast with this mold, the rest are some of my first lost foam castings, the only thing I've done with these is rinse them off and in the case of the foam ingots, scrubbed them with a wire brush to remove the sand.
TLDR; Great product, would totally buy again.
Great quality and works great for my needs. Be sure to keep in a dry place. the carbon will start to leach out if you live in a high humidify area. I keep mine in rice when not in use.
Be careful when dipping ingots into a water bucket- if the mold becomes coated in water and then liquid metal is applied it WILL BOIL! Very dangerous unless you go ahead smelting with caution. Great product though! Will use for the years to come.
Used to make over 100 copper bars so far.
I use this with a small electric metal melter for aluminum. I like the smaller ingots like this so I can measure out better. Make sure you understand how small it is.
Feature Product
- 【Composition:】99.95% Graphite. Ash content less than 0.1%. Excellent thermal conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles.
- 【Performance】Excellent thermal stability for fast heating and cooling / Well corrosion resistance to strong acid and alkali / Good thermal conductivity properties which highly shorten the melting time and save energy / Great impact resistance performance to ensure the reliability of product quality.

Love it
Haven’t tried it but it’s just a block that’s been machined so the quality is great! I don’t see how this will fail to do it’s job. Would buy again!
Husband is extremely happy with this purchase, it came exactly as described and it works perfectly. Thank you. Would recommend.
Nice Mold
I can't really say that I like or dislike anything particular, but it does look nice.
