Quality System
Quality is built in, not inspected in
Shenghua operates a full-process quality system spanning incoming material, in-process control, finished product and release — driven by data and measured against standards, so every bar survives extreme service.
Control Process
-
01
Incoming Inspection
Every lot is verified by OES analysis against its mill certificate before entering production — no off-spec material gets in.
-
02
In-Process Inspection
First-article and patrol inspection on critical operations with real-time monitoring of dimensions and process parameters.
-
03
Nondestructive Testing
Penetrant (PT) and ultrasonic (UT) testing reveal internal and surface defects — zero tolerance for misses on critical parts.
-
04
Mechanical Testing
Full mechanical tests (tensile, impact, hardness) with retained samples for complete traceability.
-
05
Final Inspection
100% dimensional and visual final inspection with a test report shipped with each part.
-
06
Release & Traceability
Lot-level traceability; mill certificate and test report delivered with every shipment.
