Sigmamotor Inc. was established in 1956. We have kept up with times and are well equipped with CNC lathes and mills along with conventional tools. We do prototype work as well as mechanical assembly. We have a thorough, documented inspection department where parts are inspected by process before they are shipped.

Our shop can turn bar stock from 1/8” to 3-½” diameter and we possess a 10” chuck capacity. We work with many materials including aluminum, brass, hot and cold rolled steels, stainless steel (300 series to precipitation hardening 15-5ph), alloys (hastalloy to titanium) and we specialize in plastics, from ABS to Zelux.
