18 Element Spectrometer to test Aluminium alloy.

Density Index Testing

Gas inclusion and porosity testing using density index of liquid metal.

Laser temperature measurement

Tool temperature measurement using laser gun.


Micrography – Outsourced – Automotive parts micrography examination to not only understand porosity but also to verify microstructure of the parts.


Radiography – Outsourced – To confirm part density and understand porosity in parts. All our domestic automotive parts require Level – 1 or Level – 2 porosity

2D Height Gauge

2D Height Gauge – On line & off line dimensional check by Mitutoyo make 2D height gauge.

Hardness Tester

Having inspection facility in HRC / BHN for components as well as tool spares such as pins, clamps etc are tested for correct hardness.

DFT Meter

Paint quality and thickness is tested after powder coating using DFT Meter.

Lux meter

For checking paint finish and visual testing, illumination standards are confirmed testing brightness of inspection area using Lux meter.


To ensure 100% inspection, most critical dimensions and areas are passed through operator friendly Attribute type of gauges. Concentricity gauge, snap gauge, flatness gauge and certain customised gauges are some other types of gauges that we use.


CMM – outsourced – Only few times we require CMM testing of dimensions, in such cases it is preferred to outsource it to a reliable quality laboratory. It also ascertains 3rd party validation.
