PMI's niche in the marketplace is in fabricating small castings
from 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 don’t do in-house, we contract out to carefully selected vendors who meet our rigid standards for quality and on-time delivery.
