A comprehensive quality control system has been established, covering every stage of the process. Starting from the incoming inspection of raw materials, advanced precision equipment such as spectrometers and metallographic microscopes is used to ensure that the furnace charge meets strict compositional standards. During production, technologies like online temperature measurement and non-destructive testing are employed to continuously monitor the quality of castings in real time. Finally, at the finished-product stage, rigorous inspections are carried out, including hydrostatic pressure tests and mechanical property assessments, to guarantee full compliance with quality requirements.
