Why Aluminum Hot Forging Process Is Better Than Casting
There are two ways that aluminum metal could be formed into other products. One of them is cold or hot forging, and the other one of casting. Casting is the process of heating aluminum above the melting point and pouring it into the mold to dry. The aluminum hot forging process, on the other hand, includes pressing the metal under high pressure to produce plasticity.
There are numerous reasons why the aluminum hot forging process is the best between the two. In this article, we are going to look at why this is the case. Here are reasons why manufacturers are going for forging and not casting:
When compared in terms of strength, the hot-forged aluminum products offer superior properties. The cast aluminum material has a problem with porosity, which makes them less strong compared to the forged ones. The high-strength features from the aluminum hot forging process are a result of the heat-treatment process. With the heat treatment, the metal develops fine grains that make it stronger.
If you are in the business and want to make money, then you need to check your profit margins. If you an alternative manufacturing process that guarantees better quality output at a cheaper cost, go for it. That’s what the aluminum hot forging process provides compared to casting. For casting, you need to heat the metal above crystallization temperature. This means a lot of energy, which is not the same as forging. The production rate of forging is lower.
Better Lead Time
The time that’s taken to producing hot forging is shorter compared to casting. With the improved technology, it is has become very easy to carry out an aluminum hot forging process. With the hydraulic machine, heating and cooling system plus some finishing machine, you good to hot forge. But with casting, the time used to produce the same aluminum products is long.
When it comes to shapes, the aluminum hot forging process offers one of the best flexibility. With the dies, it is very easy to even form the most sophisticated shapes. The coming of 3d modeling and drawing has also increased this flexibility.
The surface finishing for the aluminum hot forging process enables the production of an array of finishes. That’s because of the smooth surface that allows even for ease of engraving. That’s not the case with aluminum casting, which produces rough surfaces.
