Certifications & Compliance

At Dhananjay Group, quality is non-negotiable. Our dedicated, in-house Quality Testing facilities are equipped with a comprehensive range of precision instruments and machines to ensure every component meets the most stringent standards for dimensional accuracy, material integrity, and performance.
Comprehensive Quality Testing Capabilities
We utilize state-of-the-art equipment to perform detailed measurements and rigorous performance tests, ensuring reliability from raw material inspection through final product validation.
Dimensional & Profiling Equipment
3D Portable CMM (Romer make): For highly accurate, flexible, and on-site volumetric measurements of complex geometries and large components.
2D CMM: Precision measurement of components with strokes up to 500 \times 600 \times 400 \text{ mm}.
Profile Projector: Essential for non-contact measurement and comparison of complex profiles, threads, and small component features.
Contracer: Used for tracing and analyzing the contours (shape and geometry) of intricate components.
Surface RA Tester: Measures the roughness average (\text{Ra}) of machined and finished surfaces to ensure texture compliance.
Mechanical & Material Testing
Universal Testing Machine (UTM): Performs tensile, compression, and bend testing to determine the mechanical strength and properties of materials.
Hardness Tester: Measures the material’s resistance to permanent indentation, ensuring correct heat treatment and material grade.
PMI Testing Machine (Positive Material Identification): Non-destructive testing to verify the chemical composition and grade of metal alloys.
Weld & Finish Integrity Testing
Weld Penetration Testing: Checks the depth and quality of the weld fusion to guarantee structural integrity.
Proof Load Test for Welding: Applies a specific load to a welded assembly to verify its strength and reliability under stress.
Salt Spray Testing: Accelerated corrosion testing to assess the protective quality and lifespan of surface coatings (like zinc plating or powder coating).
DFT Meter (Dry Film Thickness Meter): Precisely measures the thickness of protective coatings to ensure compliance with specifications.
