Mechanical Testing & Micro structure examination

In exclusive for engineering and automobile industries, the various mechanical tests like, Tensile test with different capacities (25 kN, 100 kN, 400 kN, 1000 kN) Hardness (Vickers, Brinell, Rockwell, Rockwell Superficial), Impact test (as per ASTM and ISO standards), microhardness test are being carried as per various national and international Standards

 

We possess the latest technology with years of trained professionals to handle your quality assurance testing services.
