Extrusion is a cornerstone process in modern manufacturing, enabling the creation of products with complex cross-sections and consistent quality. The National Programme on Technology Enhanced Learning (NPTEL) offers a thorough framework for understanding the classification of extrusion processes and the equipment used. This article explores in detail how NPTEL classifies various extrusion processes and equipment, focusing on their operational principles, advantages, disadvantages, and applications. Throughout, we will emphasize the concept of "types of extrusion and extrusion equipment nptelnptel" to provide a comprehensive understanding.
