WebMay 29, 2024 · The extrusion process is one of the most common processes in the production world today. It involves the use of a large variety of materials like metals, plastics, ceramics, etc. The process can be done in either hot or cold when better properties are required. Extrusion processes in metals may increase the strength of the material.
The process begins by heating the stock material (for hot or warm extrusion). It is then loaded into the container in the press. A dummy block is placed behind it where the ram then presses on the material to push it out of the die. Afterward the extrusion is stretched in order to straighten it. If better properties are required then it may be heat treated or cold worked. The extrusion ratio is defined as the starting cross-sectional area divided by the cross-sectional … WebFeb 28, 2024 · Extrusion is a manufacturing process that generates profiles having a fixed cross-sectional area by pushing the billet material through a die. It is a bulk-forming process, where the stock material is deformed into the final shape under pressure (and temperature), without any melting and solidification or material removal.
