Quality Control & Testing Lab

Zero-defect delivery is our standard. Our facility includes a dedicated testing zone.

Raw Material Inspection (Composition Verification)

Before production, the raw material (copper and zinc alloy) must be verified to ensure it meets specifications and is free of unwanted impurities.

  • Spectroscopy Analysis: Techniques like X-ray fluorescence (XRF) and Optical Emission Spectroscopy (OES) are used to determine the exact percentage of copper, zinc, and trace elements like lead, ensuring the alloy grade is correct.
  • Chemical Analysis: Testing for impurities and checking physical properties of incoming ingots or rods.

In-Process Inspection

Inspections are conducted during the manufacturing process (casting, forging, or machining) to detect issues early and reduce scrap.
  • Dimensional Checks: Using Vernier calipers, micrometers, and thread gauges to measure parts hourly during production.
  • Visual Inspection: Checking for surface flaws like blisters, tool marks, scaly surfaces, or oxidation during intermediate stages.
  • Temperature Monitoring: Recording pre- heating temperatures (e.g., 840-860°C) during hot rolling.

Non-Destructive Testing (NDT)

NDT techniques check for defects without damaging the finished component, often used for 100% inspection of critical parts.
  • Dye Penetrant Testing (PT): Used to detect surface-breaking cracks or porosities on casting or machining.
  • Ultrasonic Testing (UT): Employs sound waves to detect internal voids, porosity, and cracks in castings or billets.
  • Eddy Current Testing: Rapidly detects surface and near-surface inclusions and material property changes.

Dimensional and Geometric Inspection

Final verification of the part’s shape, size, and tolerance.
  • Coordinate Measuring Machines (CMM): Used for high-precision, multi-dimensional measurements.
  • Optical Comparators/Profile Projectors: Project an enlarged image of complex profiles to check them against design
    blueprints.
