Drawing & Application Review
Our senior ceramic engineers conduct a thorough DFM (Design for Manufacturability) analysis on your CAD files or technical drawings, assessing geometry, wall thickness, thermal expansion constraints, and operational stresses.
Material & Manufacturing Confirmation
We match your application demands with the ideal ceramic formulation (Alumina 95%-99.8%, Zirconia, Silicon Carbide, Silicon Nitride) and determine precision tooling, sintering shrinkage parameters, and CNC cycle plans.
Precision Manufacturing & Finishing
Utilizing high-tonnage CIP, precision CNC machining, internal and cylindrical grinding, and plane lapping/polishing, we achieve tight dimensional tolerances up to ±0.001mm with mirror-like surface finishes (Ra < 0.05µm).
Inspection & Delivery Coordination
Components undergo ultrasonic cleaning, CMM 3D coordinate validation, and surface roughness testing within our ISO Class 6 cleanroom before clean-vacuum packaging and worldwide shipment.
