Melting Process – VAM or PM ensures minimal contamination and uniform microstructure.
-
Hot Forging & Rolling – Improves grain alignment and material strength.
-
Heat Treatment – Stress relieving and annealing to optimize ductility and stability.
-
Precision Machining – CNC milling, grinding, and shaping to customer specifications.
-
Surface Finishing – Bright rolling, polishing, or grinding for optimal appearance and performance.
-
Final Inspection – Ultrasonic flaw detection, dimensional verification, and visual inspection.
By following this strict manufacturing route, every High Purity Cobalt Plate meets or exceeds international material standards.
