High-Precision Machining Centers

Precision Machined Composites and Tooling

The Engineered Composites Incorporated (ECI) facility integrates state-of-the-art machining centers to produce precision composite parts with complex geometrical features and/or unique functional requirements. We utilize advanced CNC machining as part of our lean, vertically integrated manufacturing processes – both for product finishing and for custom tooling.

Whether we’re trimming custom molded parts, milling complex part features, or producing high-precision tool components, our CNC services deliver unmatched quality and repeatability while streamlining your project’s secondary operations.

Precision Finishing for Complex Molded Composite Parts

Beyond accurate molding and forming, our customers’ composite parts often require finely machined edges, drilled or tapped holes, and precise mating features to meet the final application specifications.

Our in-house CNC machining department is fully equipped to deliver clean, repeatable finishing for a wide range of thermoset and thermoplastic composite materials. We can thus achieve a more accurate surface finish, tighter tolerances, and/or complex part features, which would be impossible using only conventional compression molding processes.

  • Multi-axis machining for complex geometries
  • Drilling, tapping, countersinking, and slotting
  • Machining of edge features and mounting points
  • Surface finishing for dimensional control
  • High repeatability across medium- to high-volume production

Our machining processes are closely integrated with our molding department, as well as our robotic trimming and punching operations. This helps us maintain tight control over quality and deliver consistent performance from part to part. What does that mean for your end products?

  • Tighter tolerance control
  • Reduced edge chipping and delamination
  • Cleaner holes and cutouts
  • Improved downstream assembly fit and function

CNC Machining for In-House Tooling and Fixtures

In addition to part finishing, ECI uses CNC machining to support in-house tooling and mold manufacturing. Our toolroom utilizes high-precision CNC machines to manufacture and maintain production tooling, jigs, and fixtures. In-house tooling enables shorter lead times, improved part quality, and greater flexibility for any future design changes your products may require.

  • Mold base and cavity machining
  • Custom fixture development for trimming, punching, and assembly
  • Maintenance and modification of legacy tools
  • High-durability steel or aluminum inserts and components
  • Certified to ISO 9001:2015 standards and UL E495715 traceability requirements

By keeping this critical capability in-house, ECI eliminates third-party delays, simultaneously ensuring your production tools are built and maintained to the exact standards required for consistent, long-term quality and repeatability.
