During the manufacture of aluminum, you can either use forging or casting. In the forging process, metal is put through tremendous pressure to create high-strength parts. Although the primary forging method is heating, some forgings do not use heat. On the other hand, in casting, a material is heated above its melting temperature and poured into a mold to solidify and become cast. Since they are different manufacturing techniques, why is forging better than casting?
Lower cost: Die forging tools are affordable compared to die-cast forging. In manufacturing, several fabrication choices are convenient. Cost is a major determining factor. When forging, the production rate is higher than when you do the casting.
Greater strength: When aluminum forging is treated with heat, it displays mechanical properties that make its strength-to-weight ratio better than castings. In addition, forging is also porosity-free. This means it allows heat treatment processes that significantly increase the selected mechanical features. The greater strength of aluminum forging guarantees better working performance and durability.
Greater surface finish: Forging allows a variety of surface finishes. On the other hand, the surface finish of casting is not appealing or smooth. However, forging makes it easy to create smooth surfaces or sharper serrations.
Flexibility: Not all shapes are forged in aluminum forging, but there are exceptions. When you use closed die aluminum forging, you can get different incredible shapes. However, using modern tools like 3D modeling and drawings has also increased the flexibility of the models in the early ensign stages. Unlike in casting, the physical size of the component might limit flexibility in design.
As mentioned, aluminum forging is the best technique compared to casting. It offers many benefits that save you money and give you durable products.
