Custom Ceramic Parts (also known as prototypes) are precision components manufactured according to customer drawings. They are made from materials such as aluminum oxide, aluminum nitride, silicon carbide, Macor, and more, using cutting, grinding, polishing, and CNC shaping techniques. These parts often feature complex geometries, curved surfaces, micro-holes, slots, and tight tolerances to meet specific functional requirements.

Machining Process Workflow
Material Forming
Powder mixing → Pressing / Injection molding / Cold isostatic pressing
Shaping & Machining
Grinding: Surface grinding, cylindrical grinding, centerless grinding
CNC Machining: 5-axis or multi-axis CNC equipment for ultra-precision cutting, drilling, milling, etc.
Precision Polishing
Surface polishing to achieve smooth, mirror-like, or even optical-grade finishes
Product Inspection
Dimensional, flatness, roughness, and defect checks using interferometers, CMMs, roundness testers, etc.
Ultrasonic Cleaning & Vacuum Packaging
Cleaning: Ultrasonic cleaning removes microparticles to ensure cleanliness
Packaging: Vacuum-sealed to protect parts from pressure and contamination during transport
Application Fields
- Semiconductor Manufacturing: Ceramic arms, vacuum suction cups, heat spreaders
- Medical Devices: Biocompatible implants, precision probes, fluid pump components
- Aerospace: Thermal protection parts, vacuum seals, gyroscope components
- Defense: Lenses, windows, thermal management components
- Quantum Technology: Ion trap supports, quadrupole insulator brackets
- Optics: Silicon carbide mirrors, telescope lenses
