1.	Which of the following processes is not the type of metal forming process?(a) Extrusion(b) Injection moulding(c) Forging(d) DrawingI had been asked this question in exam.The above asked question is from Classification of Metal Forming Processes topic in division Forming Process of Casting-Forming-Welding II
Answer» The correct answer is (b) Injection moulding Easy explanation: Extrusion, forging and drawing PROCESS are the main general types of metal forming process, while the injection moulding is other process which is basically a part of CASTING process which INCLUDES the formation of parts by injecting the MELT into a cavity by the help of a plunger. This method is not the part of metal forming because the phase change of metal occurs during the process.
