QUALITY & INSPECTION
Quality built into every stage,
not just checked at the end.
For an OEM, one out-of-tolerance part can stop an assembly line. That is why inspection at Madhav Industries starts before production and continues until the carton is sealed.
Explore our quality process01 / CONTROL AT EVERY STAGE
Three-stage inspection system
Checks begin with incoming material, continue through production, and finish with a batch review before packing.
| Stage | What we check |
|---|---|
| Incoming material inspection | Grade, thickness, surface condition and supplier certificate for every lot of raw material |
| In-process inspection | First-off approval at each setup, then periodic checks on dimensions and form during the run |
| Final inspection | Dimensions, finish, burr-free edges and visual quality on every batch before packing |
02 / CHECKING POINTS
What we inspect
Dimensional inspection
Diameters, lengths, thickness, hole positions and thread accuracy against the drawing.
Surface-finish inspection
Polish level, scratches, dents and burrs checked under proper lighting.
Hardness testing
In-house tester for hardened blades and parts.
Material verification
Mill test certificates verified for every lot; material grade validated through spectrochemical analysis.
03 / MEASUREMENT
Our inspection instruments
| Instrument | Used for |
|---|---|
| Digital vernier caliper | Length, width, diameter, depth |
| Outside micrometer | Precise shaft diameters and thickness |
| Inside micrometer | Bore and internal diameters |
| Depth micrometer | Step, groove and slot depths |
| Air gauge | High-accuracy, fast checking of bores and shafts |
| Thread gauge | Thread pitch and fit |
| Pin gauge | Hole sizes |
| Steel rule and measuring tape | General dimensions |
04 / CALIBRATION
Reliable measurements start with calibrated instruments.
All measuring instruments are calibrated on a fixed schedule that is half-yearly through an accredited laboratory. Each instrument carries an ID and calibration due date, and out-of-calibration instruments are removed from use.
Traceability
Every batch can be traced back to its raw-material lot, production date and inspection record. If a question ever arises, we can find the answer.
Non-conforming parts
Non-conforming material is immediately segregated into a designated area, documented for traceability, and strictly controlled to prevent unintended use or mixing with conforming stock.
