Services
Tool Fabrication
We design and build custom fixtures, gages, and specialty tools for aerospace applications with tolerances down to 0.0002. Our capabilities include EDM fixtures, turbine blade tooling, and CMM nests using CNC machining and manual equipment. Our experienced toolmakers produce complex tooling for milling, drilling, and assembly operations.
Cast Urethane
We manufacture durable cast urethane and RTV silicone masking products for aerospace shot peen and grit blast applications. Our materials offer chemical resistance and temperature tolerance from Shore 10A to 80D durometer, providing lightweight alternatives to metal components with 50% weight reduction.
Composite Tooling
Our composite tooling services create resin transfer molds, autoclave molds, and trim tools for aircraft engine components and structures. With 20+ years of experience, we produce multi-piece molds requiring tight tolerances for aerospace OEMs and Tier 1 suppliers using Class A toolmakers.
Prototype Machining
We offer high-precision machining for low-volume components using 3- and 5-axis CNC equipment, manual mills, and lathes. Our capabilities include complex geometries for aerospace components, with inspection using Mitutoyo CMM equipment to verify critical dimensions.
Additive Manufacturing
Our additive manufacturing produces SLS and SLA prototypes for aerospace applications with dimensional accuracy. We create functional parts up to 26" x 14" x 21" using selective laser sintering, and demonstration models with stereolithography for fit, form, and function testing.
