Advantages & Disadvantages of Cold Extrusion

Cold extrusion is highly advantageous as it is used to withstand all the stresses that are created by the extrusion process. There are various advantages of cold extrusion over the hot extrusion, some of the important ones are listed below:

•No oxidation process

•Higher strength due to cold working

•Good mechanical properties that are provided the temperatures created, are below the re-crystallization temperature

•Closer tolerances

•Good surface finish

•Fast extrusion speeds, in case the material is subjected to hot shortness

Dimensional precision:

•Net-shaped features

•Lower energy consumption

•Higher production rates

•Cleaner work environment.

Apart from the above-mentioned advantages, there are some disadvantages as well that are associated with cold extrusion. These are lubrication cost, higher loads, limited shape complexity, and limited deformation.


Applications of Cold Extrusion

•The cold extrusion process is widely used to manufacture products from Copper, Lead, Tin, Aluminum Alloys, Titanium, Molybdenum, Vanadium, Steel, Zirconium, and Niobium.

•Some of the products that are developed using this process include various parts such as Collapsible Tubes, Gear Blanks, Aluminum Cans, Cylinders, Fire Extinguisher Cases, Shock Absorber Cylinders, and Automotive Pistons.

•Cold Extrusion is also used in the Automobile Sector, in various applications such as:

*Injection technology

*Engine control

*Fuel supply

*Automatic transmissions

*Seat technology

*Safety systems (restraint systems)


Metals that are commonly extruded include:

•Aluminum is the most commonly extruded material. Aluminum can be hot or cold extruded. If it is hot extruded it is heated to 575 to 1100 °F (300 to 600 °C). Examples of products include profiles for tracks, frames, rails, mullions, and heat sinks.

•Brass is used to extrude corrosion free rods, automobile parts, pipe fittings, engineering parts.

•Copper (1100 to 1825 °F (600 to 1000 °C)) pipe, wire, rods, bars, tubes, and welding electrodes. Often more than 100 ksi (690 MPa) is required to extrude copper.

•Lead and tin (maximum 575 °F (300 °C)) pipes, wire, tubes, and cable sheathing. Molten lead may also be used in place of billets on vertical extrusion presses.

•Magnesium (575 to 1100 °F (300 to 600 °C)) aircraft parts and nuclear industry parts. Magnesium is about as extrudable as aluminum.

•Zinc (400 to 650 °F (200 to 350 °C)) rods, bar, tubes, hardware components, fitting, and handrails.

•Steel (1825 to 2375 °F (1000 to 1300 °C)) rods and tracks. Usually plain carbon steel is extruded, but alloy steel and stainless steel can also be extruded.

•Titanium (1100 to 1825 °F (600 to 1000 °C)) aircraft components including seat tracks, engine rings, and other structural parts.
