Our Quality Standards
At Sudarsan Engineering Industries (SEI), we are committed to delivering superior quality
components by strictly adhering to ISO standards. Our quality assurance process begins with
the procurement of raw materials and continues through every stage of manufacturing,
inspection, and final dispatch.
We ensure that every product meets customer specifications through rigorous inspections and testing at various stages.

Our Quality Control Process: A Step-by-Step Approach
1. Raw Material & Alloy Inspection
- Raw material procurement as per required specifications
- Metal composition analysis to ensure purity
- Alloy preparation & quality checks
2. Casting Process & Initial Inspections
- Spectrographic analysis to verify alloy composition
- Slurry quality analysis for sand casting & gravity die casting
- First-piece casting inspection
3. Machining & Dimensional Inspection
- Precision machining compliance check
- Dimensional inspection per customer specifications
- Third-party dimensional verification (if required)
4. Physical & Chemical Testing
- Mechanical property testing, including:
- Tensile strength
- Yield strength
- Elongation percentage
- Reduction area
- Hardness & impact testing
- Corrosion resistance testing
5. Non-Destructive Testing (NDT) & Final Quality Checks
- Radiographic inspection (X-ray testing)
- Ultrasonic testing (UT) for internal defects
- Magnetic Particle Inspection (MPI) for surface defects
- Visual inspection – 100% defect-free assurance
6. Final Packaging & Dispatch
- Inspection before packaging
- Secure packaging as per customer requirements
- On-time dispatch with full compliance documents
