Glass Fiber Reinforced Plastic (GFRP) is the high-strength, lightweight champion of advanced materials, but it’ll eat standard tools for breakfast. You need a machining partner who gets it.
We specialize in CNC machining GFRP. We know the feeds, the speeds, the tool geometries, and the exact hold-down techniques to deliver clean, precise, and burr-free parts. No delamination. No fraying. Just razor-sharp accuracy in a material that defies weight.
KEY BENEFITS
Forget “good enough.” GFRP gives you a critical advantage where it counts.
| Benefit | What It Means For Your Project |
|---|---|
| High Strength-to-Weight Ratio | Lighter than aluminum, stronger than many steels. Build faster machines, more efficient vehicles, and longer-lasting components without the mass. |
| Outstanding Corrosion Resistance | Laughs off moisture, chemicals, and UV exposure. Ideal for harsh environments where metal would corrode and fail. |
| Excellent Dielectric Properties | A natural insulator. Perfect for electrical enclosures, circuit boards, and non-conductive structural components. |
| Dimensional Stability | Won’t warp, swell, or shrink with temperature and humidity changes. Your critical tolerances stay critical. |
| Design Flexibility | Complex geometries are no problem. We machine what you can design, unlocking forms that are impossible with metal fabrication. |
APPLICATIONS
This isn’t a lab material. It’s a workhorse across industries that demand peak performance.
| Industry | Typical CNC Machined Parts |
|---|---|
| Aerospace & Defense | Antenna radomes, drone arms, structural brackets, inspection fixtures, interior components. |
| Automotive & Racing | Lightweight body panels, insulating brackets, sensor housings, custom jigs and fixtures. |
| Electronics & Telecom | RF insulation panels, waveguide components, test socket bases, non-conductive enclosures. |
| Industrial & Marine | Chemical processing parts, pump components, fluid handling systems, non-metallic tools. |
| Medical & Scientific | Imaging system components, lab equipment housings, patient handling arms, prototype models. |
