What to know about forging and why aluminum forgings are more popular than aluminum castings

Updated in 2023-10-06

In metalwork, different methods are used to shape metal into the desired shape. One such method is forging. This metal processing technology allows for the production of metal parts that are inherently superior, reliable, and capable of exceptional tolerances.

What is forging?

Through the use of external force and heat, metal is shaped differently during this manufacturing process. The metal can be easily molded because it is pliable after being heated. You can utilize either hot forging or cold forging, depending on the type of metal and your design specifications.

Forging type

The hand pounding and shaping of metal by blacksmiths gave rise to modern blacksmithing. It currently makes use of a variety of technical techniques and large machinery to provide better results. Here are the various metal forging techniques.

Open Die Forging - Also known as drop forging, it transforms a piece of metal without completely enclosing the material within the die. It is done by striking the heated metal against a mold until it forms the shape of the mold.

The two die halves of closed die forging, also known as press forging, must be moved toward one another and around the workpiece using a punch. They create a forged shape when they come into touch. Although die forging is a quick procedure that ensures precision, quality, and strength, it is more expensive than other forging techniques.

Cold Forging – This method shapes metal at room temperature and includes drawing, heading, stamping, stamping, and thread rolling. Copper forging manufacturers prefer it when shaping soft metals like copper, especially because the finished product has a better surface finish and greater dimensional stability.

Other methods include: rolling, upsetting, ring rolling, pressure, isothermal and multidirectional forging. All these methods allow controlled deformation of the metal, resulting in metallurgical integrity and superior mechanical quality.

Both forging and casting techniques can be used to produce aluminum. To produce high-strength pieces, metal is put under extreme pressure during the forging process. Despite heat being the main forging technique, some forgings do not.

In casting, on the other hand, the material is heated above its melting temperature and then poured into a mold to solidify and become a casting. Since they are different manufacturing techniques, why is forging better than casting?

Lower cost: Compared to die-cast forging, die forging tools are affordable. In manufacturing, it is convenient to have several manufacturing options. Cost is a major deciding factor. When forging, productivity is higher than when casting.

Greater Strength: When aluminum forgings are heated, they acquire mechanical properties that give them a stronger-to-lighter ratio than castings. Additionally, the forging has no pores. Thus, it is feasible to carry out heat treatment operations that significantly enhance a portion of mechanical qualities. Greater aluminum forging strength ensures longer service life and improved working performance.

Higher Surface Finish: Different surface finishes are possible with forging. On the other hand, the casting's surface polish is neither appealing or smooth. However, forging can quickly produce a smooth surface or teeth with greater sharpness.

Flexibility: There are some shapes that are forged from aluminum, but not all of them. With closed-die aluminum forgings, you may create a variety of amazing shapes. The versatility of early ensign stage models has, however, significantly improved with the use of contemporary techniques like 3D modeling and drawing. In contrast to casting, the component's physical size may restrict design freedom.

When compared to casting, aluminum forging is the best technology. It comes with a host of advantages, helps you save money, and gives you a long-lasting item.
