CARBON FIBER. CARBON FIBER.CARBON FIBER.
Strength you can feel. Weight you barely notice. Precision that defines performance. Matte black, rigid, and ready — engineered for those who demand more than plastic.
Unmatched Strength and Rigidity
• Up to 38% Higher Tensile Strength – 69 MPa vs. 50 MPa for Nylon 12, giving parts more load-bearing capability. • Nearly 3× Stiffer – With a tensile modulus of 5.3 GPa (vs. 1.9 GPa), PA11 CF parts hold their shape under pressure and stress. • Over 65% Greater Flexural Strength – 110 MPa vs. 66 MPa for Nylon 12 means stronger parts that won’t bend or deform.
Superior Heat and Environmental Resistance
• Designed for high-temperature applications where Nylon 12 softens or degrades. • Carbon fiber reinforcement improves thermal stability and lowers thermal expansion for precision even under heat. • Naturally resistant to moisture and UV exposure, ideal for rigorous outdoor use.
Professional Finish and Lightweight Design
• Carbon fiber infusion produces a sleek matte black surface — functional and aesthetic right off the printer. • Delivers metal-like strength at a fraction of the weight, enabling lighter, more efficient assemblies.
Designed for High-Pressure HPA systems
• Lightweight carbon fiber composite reduces load without sacrificing strength or rigidity. • Tested for durability across extreme temperature and humidity conditions to ensure reliable field performance.
Rigid Carbon Fiber Structure
• Low expansion under heat preserves airseal integrity during rapid-fire or sustained full-auto use. • Machined precision surfaces ensure smooth magazine insertion and consistent alignment with feed paths.
Custom Cerakote & Precision Coatings
