Based in Michigan, USA, our client is a leading trade-manufacturing enterprise specializing in precision components for aerospace, medical devices, and other high-end industries. The 2 CNC turned parts in this collaboration are aircraft tubing bearing end caps made from ULTEM 2300 TAN, a high-performance engineering plastic known for its extreme heat resistance (HDT 217℃) and high strength (tensile strength 103MPa). However, its exceptionally high melt viscosity posed significant machining challenges. The client required dimensional tolerances within ±0.02mm and surface roughness Ra≤1.6μm to ensure sealing and structural stability in extreme temperatures ranging from -55℃ to 180℃.
As a certified leader in China’s aerospace precision machining (ISO 9001:2015, IATF 16949, and AS9100D), we bring over 20 years of expertise in processing high-performance materials like ULTEM and PEEK. Our capabilities include:
The two bearing end caps feature precision fit surfaces and thin-walled annular structures, while ULTEM 2300 TAN’s 15,000 Pa·s melt viscosity (10x that of normal ABS) created two critical issues:
As the client emphasized, "End cap deformation could lead to aircraft tubing leaks—a zero-tolerance safety hazard." Beyond dimensional precision, the parts required aerospace material certification (e.g., AMS 3658), a challenge for traditional machining processes to meet alongside material performance requirements.
