The Polytechnic in Mechanical Engineering College in India offers a wide range of subjects that help you build a strong foundation in core mechanical engineering concepts. The diploma covers both theoretical knowledge and practical skills so that students can understand how machines work, how they are designed, and how industries operate.
You will study Engineering Mechanics, which teaches you the basics of forces, motion, and how mechanical systems behave. Thermodynamics helps you understand heat, energy, and power generation, which are essential in engines and industrial systems. Subjects like Fluid Mechanics teach you about the behaviour of liquids and gases, which is useful in hydraulics, pumps, turbines, and automotive systems.
You will also learn Machine Design, where you study how different machine parts are designed for strength, safety, and efficiency. Manufacturing Technology introduces you to processes like welding, casting, machining, and forming — skills used in industries across India.
Modern subjects like CNC Programming and CAD/CAM prepare you for advanced manufacturing environments. Through these, you learn how to design machine parts on computers and create precise components using automated machines. Many polytechnic colleges also include Robotics to help students understand automation, sensors, and robotic systems used in modern industries.
The Diploma in Electronics and Communication Engineering (ECE) offered by colleges in Delhi, such as Puran Murti Campus, includes a broad and industry-relevant curriculum spread over six semesters. This course is carefully designed to build strong technical knowledge and practical skills in electronics and communication systems. From the first semester, students are introduced to the basics of electrical and electronics engineering. As they progress through the course, they explore more advanced concepts in digital systems, signal transmission, microprocessors, and communication technologies.
Some of the key subjects covered include material science, which helps students understand the properties and behavior of electronic materials used in semiconductors and circuits. Communication systems is another major area, where students learn how signals are transmitted and received through analog and digital channels, including modulation techniques and signal processing.
The program also covers microprocessors and microcontrollers, teaching students how programmable chips are used to control machines and devices, an essential skill in automation and embedded systems. Students gain hands-on experience with electronic instruments such as oscilloscopes, multimeters, and signal generators, which are essential tools for testing and analyzing circuit performance.
In addition, the diploma includes learning about audio and video systems, giving students practical knowledge of consumer electronics, broadcasting technologies, and entertainment equipment. The course also focuses on applied learning, which is why the final semester is dedicated to industrial exposure and project work. During this period, students participate in field training, where they apply their theoretical knowledge to solve real-world problems under the guidance of industry professionals.
