Precise CNC (computer numerical control) machining is critical in ensuring that plastic aircraft parts are durable, reliable, and lightweight. Whether its humidity, corrosion, rapid temperature and pressure changes, or other, aircraft are constantly subjected to harsh environments. As such, their parts must be up for a challenge. Precision machining is critical for all aircraft parts, but some need it more than others. For an aircraft to be in top shape, all parts must be functioning as intended. A single flawed or damaged part can affect the entire system. In this blog, we will discuss the six areas where precision is most important: the engine, avionics, sensors, airframe, connectors, and seating.
