Quality verification

9-Stage Closed-Loop Manufacturing & Quality Inspection Process.

Strict quality checkpoints from incoming raw bar stock to outbound export packaging guarantee zero-defect compliance with customer drawings.

Incoming Raw Material Inspection

Spectrometer chemical composition check, ultrasonic bar flaw testing, and steel mill certificate verification.

Process Self-Inspection

Operators check first-off piece blank dimensions, centering, and turning tolerances before batch processing.

Operator In-Line Verification

Continuous monitoring of bore fits, face runout, and tooth thickness throughout hobbing and shaping.

Routing Section Patrol Inspection

Roving QC engineers conduct random sampling and process audit across all machining cells.

Special Heat-Treatment Inspection

Metallographic analysis, carburized case depth verification, and surface Rockwell hardness (58-62 HRC) check.

Final Dimensional Inspection

Zeiss 3D CMM and Klingelnberg gear testing centers measuring lead crowning, profile, and tooth runout.

Finished Product Inspection

Flank roughness profiling (Ra ≤ 0.4 µm), tooth contact pattern rolling check, and spline go/no-go gauging.

Anti-Rust & Packaging Inspection

Ultrasonic cleaning, high-performance anti-rust oil application, and individual vacuum vapor barrier wrapping.

Outbound QA Re-Inspection

Final pre-dispatch audit of crate seaworthiness, moisture-proof barrier, barcode labeling, and EN 10204 3.1 MTR records.
