Quality control and Quality assurance.

We have been certified by lS09001、OHSASl8001、ISO14001、ABS、GL、KR、BV、CCS、CWB、ASME、AISC.

We are also one of the members of AGMA.

We have adequate measuring instruments、equipments and resources to verify and meet the desired quality of the products.

· The chemical composition of the raw material is verified by both our lab and the spectrometer.Quantum of check:100%.

· Mechanical property testing of raw material is verified and approved by our lab and it is also periodically verified by an external agency.Quantum of check:100%.

· Ultrasonic testing, dye-penetrant examination,magnetic particle testing and nitric acid detection is used on various components at receiving & final inspection for crack detection.Quantum of check:100%.

· Heat treated components are inspected for case depth, microstructure and hardness with change in depth.Quantum of check:100%.

· Gear quality examination:Using Zeiss CMM,Leitz CMM, KlingeInberg tester P350 offline detection, HÖFLER/Niles/Gleason-Phauter tester online detection at various manufacturing locations.Quantum of check:100%.

· CMM is used to measure gearbox casings,planetary carrier and other components on assemblies at various manufacturing stages.

· We have receipt inspection to control the supplier's receipt products.

· We have set up first piece inspection and approval process during manufacturing.

· We have 100% quantum inspection of all the parts at the time of final inspection.

· The final product quality has been ensured by 100% verification of assembly parameters,hardness,accuracy, no-load testing, vibration, running smoothness before delivery.
