PMI® - Precision Metalsmiths, Inc.Specializing in small parts
Small wonders: PMI capabilities
PMI's niche in the marketplace is in fabricating small castings small castingfrom fractions of an ounce to 10 pounds. The maximum weight for our aluminum castings is five pounds. The maximum dimensions of our castings are 12 inches by 8 inches by 4 inches.

Alloys available ­ At PMI, we have cast over 200 different ferrous and non-ferrous air-meltable alloys. Our family of alloys includes numerous grades of:

  • Steel ­ carbon and low alloy, tool steel, 300 and 400 series, stainless, precipitation hardened, high nickel alloys, high cobalt alloys, electrical/magnetic
  • Aluminum ­ 200 series, 300 series, and specialty alloys of aluminum with copper, magnesium, manganese, silicon, and other metals to adjust mechanical properties
  • Ductile Iron ­ as-cast and austempered ductile iron (ADI)
  • Copper-based ­ red and yellow brass, silicon brass and bronze, beryllium copper

Volume Considerations ­ A typical part has annual quantity requirements that range from 1,000 - 2,000 parts up to a few hundred thousand; however, PMI investment casting might be cost-effective even when the quantities are relatively small. $600 minimum order.

Prototyping ­ The PMI ProtoCast® system is a development tool that permits you to see a part in metal without tooling. By casting the part from a pattern constructed from machineable wax, we can offer you a way to test part function, design, or alloy choice before you commit to tooling cost.

Finishing Services ­ PMI will gladly furnish you with complete parts. Our services include heat treating, machining, anodizing, coating, plating, painting, and simple assembly. What we donít do in-house, we contract out to carefully selected vendors who meet our rigid standards for quality and on-time delivery.

PMI Proto-Cast® process

PMI machinists use our patented Proto-Pat® material to form a precise model of a part. Using our exclusive Proto-Cast® process, the model is used to create an accurate investment casting in the specified alloy. This process offers significant savings when compared to other prototype development methods.
