Lead Pouring Molds

Recommended Posts

I just wanted to find out what material have any of you used to make lead molds with. Aluminum is clearly number one material but if you dont have it what do you think the best alternative should be. I have been pouring using wood (clear maple) and that has worked ok so far. I wanted to try some bondo to see how that would work.

  I made some umbrella rigs using some of the putty that gets rock hard like steel. That worked well also. Any input will be helpful. Thanks.

Silicone molds will stand up to melted lead, at least for some time.  The Silicone comes in two versions, the two part liquid and the two part putty.  The two part putty sets up faster and takes the heat of the lead much longer.

 

If your molds are pretty detailed, the two part liquid is probably better for your needs, but it does not last as long.  I prefer the putty.

I use the Alumilite High Strength 2 for my liquid, but the putty shown in the above link for a longer lasting mold.
