Surface Finish:
Sand casts have a grainy surface texture, just like most engine blocks do.
Plaster casts can show fine details like a fingerprint if done properly.

Sand Casting vs. Plaster Casting:
We can cast your parts using either a sand mold or a plaster mold. Sand casting is faster and cheaper but the surface is rougher, and complex parts are difficult to cast. Plaster casts cost more and take longer because more labor & materials are involved; however, complex parts and nice surfaces are possible. We will help you decide, based on your goals.

Finishing Options:
We plan to offer anodizing and powder coating options in the future.
