Our 6-Step Quality Process
Pre-Process Inspection
Every incoming component is inspected for material grade, dimensional accuracy, and surface condition before heat treatment begins. Non-conforming parts are flagged immediately.
Controlled Induction Process
Our CNC-controlled induction systems maintain precise power density, heating time, and coil gap. Each parameter is set and locked per component specification to ensure repeatable results.
Real-Time Temperature Monitoring
Infrared pyrometers and temperature sensors monitor the surface temperature throughout the heating cycle. Deviations trigger automatic adjustment or process halt.
Quench Control & Verification
Polymer and water quench concentration, temperature, and flow rate are precisely controlled for every batch. This ensures uniform martensite formation and prevents cracking or soft spots.
Rockwell Hardness Testing
Every batch is tested on our calibrated Rockwell hardness tester. We verify surface hardness (HRC), core hardness, and case depth on sample pieces. Minimum 3 points tested per batch.
Hardness Report & Certification
A documented hardness test report is issued with every batch — showing component ID, material, target vs achieved HRC, case depth, and operator sign-off. Required for OEM and export orders.
Process Specifications
Certifications & Standards
ISO 9001 Quality Management
Our quality management system follows ISO 9001 principles — standardised process documentation, equipment calibration schedules, and traceability for every job.
OEM & Export Grade Standards
We supply induction-hardened components to OEMs and export manufacturers requiring documented quality assurance, dimensional accuracy, and consistent batch-to-batch repeatability.
Calibrated Testing Equipment
Our Rockwell hardness testers, case depth measurement instruments, and pyrometers are regularly calibrated. Calibration certificates available on request.
Full Traceability & Documentation
Each job is logged with component details, process parameters, operator ID, and test results. Records are maintained for a minimum of 2 years for re-inspection or audit purposes.
Documents We Provide
Every job at Thakur Industries comes with proper documentation for quality assurance, OEM compliance, and audit readiness.
