Core Aerospace Machining Capabilities

CNC Machining
Achieve precise, high-tolerance parts with advanced CNC milling, turning, and multi-axis machining. Ideal for both prototype and end-use metal or plastic components.

Sheet Metal Fabrication
Cut lightweight, durable aerospace components using laser cutting, bending, punching, and stamping. Sheet metal fabrication produces aircraft brackets, enclosures, chassis, and panel assemblies that meet structural standards.

Injection Molding
Efficiently produce complex plastic parts with rapid turnaround times. We offer bridge tooling and production tooling for high-volume runs with consistent quality.

3D Printing
Quickly iterate product designs with industrial-grade additive manufacturing. Great for complex geometries, functional prototypes, and low-volume end-use parts.

Wire EDM
Precision cutting for hard-to-machine materials and intricate shapes. Ideal for tooling, dies, and tight-tolerance automotive components requiring exceptional edge quality.
Low-volume, cost-effective production of aerospace-grade parts for functional testing. Urethane casting provides an excellent surface finish and quick replication of parts.

Advantages of CNC Machining for the Aerospace Industry
Material Choices
Aerospace parts require materials that can deliver performance under extreme conditions. CNC machining supports a wide range of aerospace-approved materials, including aluminum and titanium.
Prototype to Production
Rapid prototyping and low-volume production can happen on the same equipment, reducing the lead times and accelerating product development cycles.
Complex Geometries
Advanced 5-axis CNC machining enables the production of complex intricate designs that are critical for aerospace weight-saving applications. Components like turbine blades and engine mounts can be machined in fewer steps with better accuracy.
Cost Efficiency
CNC machining offers scalable manufacturing with predictable costs for OEM manufacturing and reduces the need for multiple operations and secondary finishing operations to achieve better tolerances and surface quality.
