Rigorous Quality Assurance for CF8/304 Castings
To ensure zero-defect delivery for your critical projects, our in-house laboratory conducts 100% traceable quality inspections throughout the manufacturing process:
Chemical Composition: Verified by OES Spectrometer analysis for every heat/melt.
Mechanical Properties: Tensile strength, yield strength, and elongation testing.
Dimensional Inspection: Coordinate Measuring Machine (CMM), 3D scanning, and digital calipers.
Non-Destructive Testing (NDT): X-Ray radiography flaw detection, Liquid Penetrant Testing (PT), and Magnetic Particle Testing (MT) available upon request.
Leak & Pressure Testing: 100% pressure-tested for valve bodies, pump impellers, and fluid control parts to prevent porosity leaks.
Value-Added Post-Casting Services
We provide a comprehensive one-stop solution, taking your project from raw liquid metal to finished, assembly-ready components:
Precision CNC Machining: CNC Turning, Milling, Drilling, Tapping, and Boring.
