Quality

Utilization of systematic manufacturing techniques enables us to deliver consistent quality and takes short lead-time for production requirements. Further, improvisation, constant assimilation and adoption of latest international technology, helps us to meet the growing industry requirements.

Our in-house Quality Control Division & well equipped test laboratories ensures that the quality standards are in conformance to international benchmarks, at every stage of the production.

We conduct a host of quality test for all our products. Some of the tests we conduct are:

Test of Raw Materials
Forgings that are duly isothermally annealed and normalized are procured from the reliable suppliers. They are subjected to Dimensional and Metallurgical checks before any further processing. The tests include:

Visual inspection for cracks and folds

Chemical composition check by spectra analysis

The raw materials are also tested for

Hardness

Harden ability

Micro Structure

Grain Size and Grain Flow

Tests conducted for Transmission Gears and Shafts include

Tooth thickness by MOT / DOP

Root Diameter

PCD Run out

Lead and Profile

Surface finish

Patrol inspection is done at defined intervals. We verify and record various parameters on process control charts.

Tests conducted for quality assurance of Gears include:

Tooth thickness

PCD Run out

Backlash with mating parts

Tooth contacts

Before Heat treatment, inspection is done to ensure removal of all sharp edges and burrs.

A gamut of tests conducted for quality assurance for all our products are:

Crack detection of ground surfaces by Magnaflux.

Heat Treatment.

Checks on Case Depth.

Inspection of Core and Surface Hardness.

Micro Structure testing.

Testing of Flatness of Crown Wheels.
