PRECISION QUALITY ASSURANCE
Quality Control & Inspection
Advanced dimensional metrology, coordinate measurement, and rigorous testing protocols ensuring micron-level accuracy, complete material traceability, and zero-defect output.
Quality Engineered Into Every Stage of Production
At Kalp Turnkey Services, quality is not a post-production check—it is a core engineering discipline embedded across every manufacturing step.
Operating under a certified ISO 9001:2015 Quality Management System, our dedicated, climate-controlled metrology laboratory is equipped with world-class measuring instruments for complete physical and metallurgical validation.
Our flagship inspection asset is a large-envelope Coordinate Measuring Machine (CMM) with measuring travels of X-800 × Y-1500 × Z-600 mm, enabling high-precision verification of complex geometries, tight bore tolerances, and geometric dimensioning & tolerancing (GD&T).
We also operate high-resolution Video Measuring Machines (VMM / Profile Projector), digital surface roughness testers (Mitutoyo SJ210), electronic height gauges, and comprehensive hardness testing units (Micro Vickers, Rockwell, and Brinell).
Every batch is delivered with full Manufacturing Data Books (MDB), including Mill Test Certificates (EN 10204 3.1 MTC), NDT reports, heat treatment charts, and detailed dimensional inspection records guaranteeing 100% traceability.
