Extrusion | Types of Extrusion Process, Advantages and its Applications By Shree Sai Extrusion Technik Pvt. Ltd.
What is Extrusion? Extrusion is a type of forming process (which is a type of manufacturing process) in which a metal is confined in a closed cavity and then allowed to flow through only one opening so that the metal takes the shape of opening. In other words it is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. Theextrusion process can be done with the material hot or cold.
Types of extrusion processes: 1. Direct (or forward) extrusion- This method employs a power operated ram and a container into which the metal is kept for confinement. A dummy block is used between ram and hot metal. Because of ram pressure, metal first fills the cylindrical shape and then is forced out through the die opening until a small amount is left in the container. Finally it is sawed off next to the die and butt end is removed.2. Indirect (or backward) extrusion- This process is similar to direct extrusion except that the extended metal is forced out through a hollow ram. No friction works between the metal billet and the container walls since the billet does not move the container. In comparison of direct extrusion, less force is required in indirect extrusion.
Advantages of extrusion: Low cost per part Flexibility of operation In hot extrusion, post execution alterations are easy because product is still in heated condition. Continuous operation High production volumes Many types of raw materials can be used Good mixing (Compounding) Surface finish obtained is good Good mechanical properties obtained in cold extrusion
