Sand Casting Sandbox, Aluminum Alloy Delft Clay Casting Molds, Small DIY Metal Jewelry Casting Mold, High Temperature Jewelry Ring Casting Sandbox Melting Pot for Jewelry Makers

Very nicely done. Looks very durable. Have yet to use it but looking forward to use it.

This casting mold looks functional at first glance, but it quickly becomes a headache. There are no built-in vent holes, which leads to trapped air and bad pours. The edges are overly sharp and uncomfortable to handle, and once you pack it with sand, the two halves seize together like glue. It takes serious effort to pry them apart without damaging the mold or your work. Not worth the hassle especially if you’re expecting a smoother workflow.

Works well

Great mold. Perfect for casting small molds for jewelry and even small figures. It's easy to use and the final products are. great.

Machined decently but can get stuck trying to slot the pieces together. Make sure you keep it clean for your sand casting.

Frustrating to use as all the sand just leaks out of the hole. Seems extremely easy with that sprue hole but that was not the case in my finding.

There is no channel inside to prevent the sand from sliding out of the flask. When the half are pulled apart the flask pulls off and the sand stays in place. Also there is no alignment mark.

UPDATE: Was able to complete a small casting, picture included, out of zinc/zamac. Patience is necessary. Would be better if ID of tube had a bit of texture so the sand would stick better to it but worked out fine.Measured with caliper: 2.54" ID, 2.825" OD and 2.625" length when assembled with .975" side port. Better to be larger than the description as opposed to smaller. Should work alright for casting small items. Mold separation features should be smoother; machine cut marks result in rough separation. Pour opening has very sharp points on it; manually chamfer or break the edge to prevent cutting or stabbing your fingers as I did.
