Non-Destructive Testing (NDT) Services for Premium Investment Castings

Non-destructive testing (NDT) represents a critical quality assurance methodology that evaluates material integrity without compromising component functionality. By leveraging advanced thermal, acoustic, optical, electromagnetic, and radiographic technologies, our NDT services identify subsurface anomalies and surface defects with micron-level precision across all engineering materials and complex geometries.

Comprehensive NDT Capabilities:

1. Digital Radiographic Testing (X-Ray)

Our state-of-the-art X-ray inspection system delivers:

• 450kV high-resolution imaging for thick-section castings

• Real-time DR detection with 0.1mm sensitivity

• Automated defect recognition software

• ASTM E94/E1032 compliant reporting

Defect Detection Spectrum:

• Gas porosity (0.3mm minimum detectable size)

• Shrinkage defects (dendritic/filamentary patterns)

• Hot tears and cold cracks

• Inclusions (slag, sand, oxides)

2. Metallurgical Analysis

Our material science laboratory provides:

• Optical emission spectroscopy (OES) for full elemental composition
