We are the world class engineering manufacturer providing the highest quality products, services and solutions to our customers.


Testing Facilities (Material Testing Labs)

All products undergo through inspection and tests by out Quality Assurance Department at varios stages of manufacturing according to internationally established inspection procedures and methods. HMC is equipped with both destructive and non-destructive testing facilities and a metrological laboratory. 


Tensile testing of metallic materials on Universal Testing Machines (10 Tons, 30 Ton Tons, 60 Ton and 100 Tons)
Hardness testing , Bench type  and portable (Rockwell,Brinnel and Vicker)
Bend testing of metallic materials.
Charpy Impact Testing both at room temp and below zero
Charpy Impact Testing Machine 15/30 Kg-m/CM2
Compression Strength of refractory materials


i. Spectrometric

The department has unique installation of most modern spectrometer (Spectromax Germany of 26 elements) for analysis of Iron/ Steel and Copper based materials / alloys, adjacent to the melting section of HMC to provide accurate reliable and fast track analysis in a  minimum time,  since good process control requires prompt feed back.

ii. Wet Chemistry/analysis

All foundry inputs such as Ferro Alloys (Ferro Silico, Ferro Manganese, Ferro Chrome, Ferro Nickel & Ferro Vanadium etc), Al, Ni, Cu, Tin, Lead and their alloys are got checked before being incorporated into production function, in addition to these following testing facilities are also available.

–              Physical & chemical testing of silica sand and Bentonite Clay.
–              Refractory Materials of all kinds
–              Sodium Silicate, Water and Oil etc
