Main Advantages of Warm Extrusion

Warm extrusion is a forging method that does not require much heat. Warm extrusion is neither hot nor cold. It is a method that is becoming popular in the manufacturing industry.

Warm extrusion popularity is contributed by some of the advantages that cold forging does not have. The benefits of this method are similar to those of hot extrusion but have explained the main advantages of warm extrusion below.

Lower Forging Press Loads

The first advantage of warm extrusion is low forging press load. When the metal is heated below crystallization, it becomes easier to forge it. The external force is reduced when pressing to form the desired shape. The reduction of force lowers the cost of buying many press equipment and saves pressing time.

Surface Quality is Good

The other advantage of warm extrusion is the surface of the product is good. After the warm extrusion process, the heated forge is improved to withstand atmosphere and physical conditions. The forging parts become strong, and they are hardened when they cool. The process increases the surface quality and the forging part’s attractiveness.

Flexible Shapes

The other advantage of warm extrusion is the ability to forge flexible shapes. The forging parts are flexible to designs of the demand at hand.

Greater Workpiece Ductility

Warm extrusion increases the flexibility of the forged part. This advantage is another main reason warm extrusion is preferred over cold extrusion. Ductility is an element that must be considered because the parts are extensively exposed later while working. This forging method makes the parts produced more effective and reduces the wearing of parts.

Mass Production

Mass production is another advantage of warm extrusion. At a given time, a manufacturer can produce many demanded forged parts. This advantage is because the workpiece becomes flexible quickly; hence the designs are made faster. This warm extrusion method also requires less pressing tools.

Warm extrusion comes with many advantages, and that is why many manufacturers are using the method despite it being the latest method of forging metals.
