Diploma in Mechanical Engineering

Overview

Mechanical engineering is everywhere: in cars, machines, kitchen appliances, and even in your ceiling fans. And guess what? You do not have to wait for 4 years to master it, because Diploma in Mechanical Engineering has got you covered. A Diploma in Mechanical Engineering is a faster and more practical route, starting after your 10th class. 

Thermodynamics, CAD, machine design, workshops, and labs are included in this so you do not get overloaded with theories. The Diploma in Mechanical Engineering is the right choice if you are interested in machines and do not want to waste your time.


What is Diploma in Mechanical Engineering?

Diploma in Mechanical Engineering is a technical and practical degree that spans 3 years. Students can opt for it right after class 10th. The course is designed to build strong basics in mechanical systems. You learn how machines, engines, and tools work. And how to fix or improve them. You also learn in labs and workshops through working with real tools and real parts. That is what makes Diploma in Mechanical Engineering different.

  • The duration of Diploma in Mechanical Engineering is 3 years and can be pursued after Class 10th.
  • Admission is based on merit and entrance exams like JEECUP, JEXPO, and Odisha DET.
  • Suited for those interested in machines, mechanics, and robotics.
  • Top recruiters are NTPC, Bajaj, Ford, Honda, BHEL, L&T, and Ashok Leyland.
  • Common job roles are Mechanical Engineer, Technician, Sales Engineer, and Manufacturing Manager.
