Ep. 11 - Extrusão a Quente vs Extrusão a Frio: Qual a diferença? #welding

Welcome back to the channel! Continuing our series on Manufacturing Processes, today we're going to delve even deeper into the world of Extrusion! 🚀 Did you know that the temperature at which the metal is worked completely changes the final result of the part? In this video (Module 7), we'll unravel the calculations behind extrusion and compare hot and cold methods. In this video, you will learn about: 🔹 Geometric Parameters: What is the Die Angle (α), how to calculate the Extrusion Ratio, and what DCC (Diameter of the Circumscribed Circle) means. 🔹 Hot Extrusion: How metals with low ductility are worked at high temperatures (up to 1300°C for steels!) and what the challenges of the process are, such as die wear and oxidation. 🔹 Cold Extrusion and its Advantages: Why cold forming guarantees better mechanical properties (work hardening), precision in tolerances, and an impeccable surface finish. 🔹 Impact and Hydrostatic Extrusion: The secrets behind the manufacture of thin-walled tubes and the use of pressurized fluids to eliminate friction. 👇 Leave a comment: Considering the problems of Hot Extrusion, which do you think is the biggest challenge for the industry: excessive die wear or oxidation of parts? I want to know your opinion! 👍 Did the lesson help?
