In the aerospace field, advanced ceramics and hard-brittle glass have become core materials for critical structures and functional components due to their excellent properties.
In the aerospace field, advanced ceramics and hard-brittle glass have become core materials for critical structures and functional components due to their excellent properties.
The use of technical ceramics in extreme aerospace environments is well known. Some of the most demanding applications are found in propulsion and satellite systems, where ceramics operate in ultra-high vacuum providing electrical insulation whilst withstanding high temperatures, intense radiation, and rapid thermal cycling.
The ability of technical ceramics to survive and deliver consistent performance across a range of aerospace applications—from electric propulsion and navigation systems to optical payloads and thermal control—demonstrates the scope and capability of the materials we offer.
We provide custom ceramic components and precision machining services tailored specifically for aerospace applications, supporting both prototype development and low-to-medium volume production.
Across aerospace applications—such as attitude control, navigation systems, electric propulsion, satellite structures and payloads, and optical and laser systems—ceramics and glass are indispensable in critical components requiring high precision, thermal stability, and reliability.
Delivering aerospace-grade precision with tolerances up to ±1 um for mission-critical components
Aerospace systems—especially high-precision instruments such as Ring Laser Gyroscopes (RLG), satellite optics, and vacuum subsystems—require materials with exceptional dimensional stability, thermal resistance, and long-term reliability. Advanced ceramics and glass materials play a critical role in ensuring performance under extreme conditions.
In the aerospace field, Jundro has served numerous global clients, providing high-precision, high-reliability technical ceramic solutions to many industry-leading organizations, including GE, ESA, and China Aerospace Science and Technology Corporation.
Precision machining for complex aerospace ceramic and glass components
We have supplied high-precision Macor and Shapal-HI-M ceramic holders and fixtures for scientific research projects at leading institutions such as the National University of Singapore and the University of Maryland, supporting demanding applications in vacuum, optical, and advanced research systems.
