Production Process
- Refractory metal raw material inspection → precision plate leveling → CNC cutting & blanking → integral precision stamping via standardized molds → high-precision dimension calibration → edge deburring & polishing → surface precision cleaning → triple inspection (material purity, dimensional tolerance, appearance defect) → sorting & classification → finished product packaging → delivery with complete test reports
