Extrusion is pretty good for when you need a strong but simple tube. Including things like light poles and lamp posts. Extruded metal tubes are often combined to create more complex structures, and this process can also used in some cases to add simple holes or special shapes to the rod. wire nail making machine
Here are the typical steps of the metal casting process:
Metal billets formed using processes of melting, solidification, and rolling. The billet is then heated for the extrusion process. Making the metal more pliable and easier to shape.
Pressure apply to the billet, with dies used for the extrusion process with great precision to ensure a good fit.
The metal is completely forced through the die, then cooled and hardened. The extruded metal is then cut to the desired length, which may require a grinding step depending on the shape of the final piece.
Various processes, including annealing, coating or others, may also apply to the metal as it is extruded.
aluminum and steel
Forgings can make from a variety of metals. But aluminum and steel are particularly common materials due to their strength and flexibility. It has many advantages over the cold drawing process depending on your needs:
Precise dimensions
Extrusion is a faster process than cold drawing. Extrusion creates more precise dimensions compared to cold drawing. Extruded metals have a smoother surface than drawn metal, making them ideal for certain applications such as food processing equipment and medical devices.
Extruded products generally cheaper than cold drawn products.
Plastic deformation is less of a concern with extruded products and it is easier to achieve a perfectly round shape.
Metal products
There are several common examples of extruded metal products in today’s world. For example, square metal tubing is a common metal rod often used for frame casing and other purposes, while steel I-beam is often used in complex structural applications. Other options include round tubing, 80/20 framing, channel tubing, and various forms of metal rods and wires.
Cool drawing
Cool drawing On the other hand, cold drawing is a process that is similar in some ways to extrusion—for example, using a metal block preformed for the process—but also differs from other major concepts. During cold drawing, the billet itself is not actually part of the process. Instead, the metal fed through a series of dies. Each slightly different, to change the size of the metal as it fed.
Because each pass creates a smaller piece of metal, you can push more total metal through the process compared to extrusion—but this is offset by one key difference: Pull casting requires more passes to create the finished product. Unlike extruded tubes and beams, cold drawn pieces must be passed through dies several times to achieve their final shape. While extrusion simply pushes the metal through a die to fit the desired shape, pull casting requires each pass to progressively reduce the size. Until you reach your goal.
