MED Department Image

The Department of Mechanical Engineering came into its existence right from the inception of the then Regional Engineering College Hamirpur (now National Institute of Technology Hamirpur) in the year 1986 and served as catering department to other disciplines. The discipline of Mechanical Engineering started offering undergraduate programme leading to four year Bachelor of Technology (B.Tech) degree in Mechanical Engineering in the year 1994. The first batch was started with an intake of 30 students which has now been enhanced to 60 students by the Ministry of HRD, Government of India from the session 2006-2007 which has further been enhanced to 90 students. Since its existence, 21 Batches of Undergraduate students with B.Tech Degree in Mechanical Engineering, 14 batches of Postgraduate programme i.e. M.Tech. (Thermal Engineering) and 7 batches of M.Tech. (CAD CAM Engineering) have passed. Apart from this about 20 students have got their PhD in various areas of specialisation i.e. Thermal, Production, Materials and Design. The department has a separate building housing the various laboratories viz : Strength of Materials, Theory of Machines, Dynamics of Machinery, Mechanical Measurements and Control, Heat Transfer, Refrigeration & Air Conditioning, Turbo Machines, Production, CAD/CAM, Metrology & Heat Engines, lecture rooms, seminar room, faculty chambers and office.
