What Grounds Passenger Jets? AC Impellers & Oxygen Latches Exposed
The crux of unplanned grounding of passenger aircraft is often hidden in the “micro battlefield” of air conditioning impellers and oxygen latches – the corrosion fatigue of traditional aluminum alloy impellers and the low-temperature embrittlement of zinc alloy latches, exposing the lag of aviation material design in extreme working conditions.

Flight Control Chassis & Connectors: Top 8 Hidden Dangers Exposed
The hidden dangers of the flight control chassis and connectors are by no means minor problems, but key factors related to the safety of the entire aircraft. From material fatigue to signal interference, from failure in extreme environments to corrosion risks, each hidden danger may trigger a chain reaction

What Breaks First? Shock Absorber Pistons & Radar Brackets Under Fire
The shock absorber piston often breaks down first – high-frequency impact and extreme temperature accelerate its fatigue fracture, leading to chassis failure; and once the radar bracket is damaged, the consequences are even more fatal

Can Polyetherimide Filament Be 3d Printing?
Polyetherimide (PEI) filament is not only a viable option for 3D printing, but also a revolutionary material for high-performance industrial manufacturing. Through high-temperature printers (nozzle>350°C, hot bed>150°C) with closed chambers and negative pressure exhaust systems

What is the purpose of knurling?
The core purpose of knurling is to permanently change the surface characteristics of the workpiece through mechanical deformation without adding any additional materials, which not only enhances the friction (friction coefficient can be increased by 300%-500%), but also achieves anti-slip function.
