Diploma in Mechanical Engineering


The Diploma in Mechanical Engineering is a 3-year polytechnic study that students can pursue after completing class 10th. It focuses on the Design, Construction, and repair of Mechanical Equipment using Basic Mechanical Principles. 

Mechanical Diploma or Mechanical Engineering Polytechnic courses are available to students immediately after their 10th or equivalent test. Mechanical Diploma courses require a minimum of 55% marks in class 10. Candidates from reserved categories are eligible for a 5% relaxation. Admission to the Diploma in Mechanical Engineering Courses is based on entrance exams administered by several state examination boards.

  1. Is a Diploma in Mechanical Engineering a good course?
    This is one of the most reputable and oldest engineering departments in the country. It is the best department for students interested in a career in engineering. In both private and public organisations, Diploma in Mechanical Engineering graduates receive high salaries.
  2. What is better, doing a Diploma in Engineering after the 10th or B.Tech/B.E after the 12th?
    Both of the mediums are good but the Diploma holders have benefits. Because most of the Subjects of the B.Tech or B.E are covered in the Diploma course so it would be like a revision of the course thus we can say they have a better base for the course. Another benefit Diploma holders have is that they would have a job after the course and can pursue further higher study as part-time or distance learning.
  3. What are the top specialisations of Mechanical Engineering?
    The top specialisations in Mechanical Engineering are Biomechanical Engineering, Controls, Design, Energy Science and Technology, Manufacturing, micro-Electromechanical System, and NanoEngineering.
  4. How many subjects are there in the Mechanical Engineering Diploma?
    The Mechanical Diploma is divided into 6 semesters with 6 to 8 subjects in each semester, depending on the university.
  5. What is the scope of a Diploma in Mechanical Engineering?
    The scope of Mechanical Engineering in India is vast, with opportunities available in various sectors like Automobile, Aerospace, Energy, Construction, and many more.

Other specialisation in Diploma: - 

Diploma in Civil Engineering, Diploma in Information and Technology, Diploma in Aeronautical Engineering, Diploma in Electronics and Communication, Diploma in Automobile Engineering, Diploma in Chemical Engineering, Diploma in Instrumentation Engineering, Diploma in Production Engineering.
