Step 6: Remove the casting from the mold.

When the metal has cooled and solidified, you can remove it from the mold. If you cast into a single-use mold, you can break away the mold from the casting. If you used a plaster investment, you will want to quench the plaster in water after the metal has solidified. The water will help break away the mold. For reusable molds, you may use ejector pins to extract your casting.

Step 7: Finishing

File and polish your solid metal cast! This may involve cleaning your cast metal object, like scrubbing away excess mold material in water, breaking off the casting gates with clippers for small objects, or even an angle grinder for large pieces.

Learning how to cast metal

Whether you want to cast a small ring or a complex piece of metal for a car engine, the possibilities in metal casting are endless. The type of metal casting you choose to pursue will depend on your vision for the final product. If you are interested in pursuing jewelry, you will want to work with precious metals such as gold, silver, and platinum. If more industrial projects pique your interest, your casting may range from smaller aluminum tiles to a cast-iron skillet. Once you nail down your goals, you can explore options to educate yourself.

We always recommend beginners start in an in-person class to cover safety requirements, gain access to a studio, and learn metal casting from a professional.

What are the different types of metal casting?

The main types of metal casting utilize either expendable or non-expendable molds. Expendable mold casting utilizes a single-use mold made from resin-bonded sand, ceramic shell, plaster investment, or foam. Common types of metal casting that utilize expendable molds are lost wax casting, investment casting, and sand casting. Non-expendable molds are reusable and permanent molds and made from cast iron or steel. Non-expendable molds are used in die casting and slush casting.
