Two Types of Wedding Ring Manufacturing Methods: Forging and Casting.

Although not widely known, there are two major methods of manufacturing wedding rings: forging and casting. Here, we will explain each of these manufacturing methods.

What Is Forging?

The forging process is a traditional manufacturing method that originated in Germany and has been around in Japan for centuries. It involves compressing a mass of metal, softening it by applying heat, and cutting, hammering, and stretching it repeatedly with a roller or hammer to form the ring. The forging process requires a great deal of time, skill, and experience. With that said, it is a time-consuming and costly process. Rings forged with this method are more durable and have a high degree of precision.

What Is Casting?

The wax casting method relies on pouring metal into a mold, a concept similar to making chocolates with mold. Before working on the actual ring, a resin prototype is created using a 3D printer. Next, the mold is created based on the form of the prototype. Once the mold is ready, precious metal is then heated, poured into the mold, and cooled to form the jewelry.

Pros and Cons of Forging Method

Advantage #1 Durable

The primary benefit of forging is strength. Forging is a process of forming metal by applying pressure or beating it into shape. When force is applied to the metal, unwanted air bubbles and gases are knocked out of the metal, the interior is crimped, and crystals are oriented. As a result, the metal becomes stronger.
Wedding rings made by the forging process have the great advantage of high density and hardness, and are resistant to pressure and deformation.

Advantage #2 A Comfortable Fit

The advantage of forged wedding rings is that they are comfortable to wear on the finger because the hard, forged surface can be polished carefully to enhance the brilliance and create a smooth surface finish. It is also characterized by its weight and the firmness of the metal's density.

Advantage 3_Everything is one-of-a-kind

Forging is a manufacturing method where each piece is made one by one, resulting in all pieces being one-of-a-kind. Since no prototype is required and each piece is formed from precious metal ingots, it is easy to change the width and thickness of the piece, allowing it to be arranged to your liking.

Disadvantages of Forging

The disadvantage of the forging process is that it is difficult to create complex shapes because of the process of forming and cutting by beating. Another demerit of the forging process is that it is not suitable for mass production, such as making many identical shapes at a lower cost, because no prototype is used.

Cast wedding rings, advantages and disadvantages

Advantages of Casting

Since the molding is done by pouring into a mold, complex designs can be accommodated. For example, arms can be designed with wavy or finely patterned designs. This high degree of freedom is a major advantage of the casting process. Another major advantage is that it is suited for mass production. With a single mold, several rings of the same design can be made simply by repeating the process of pouring, cooling, and hardening metal.

Disadvantages of casting

Casting is a process in which molten metal is poured into a mold. Since there is no process of forging the metal, the density is uneven and crystals are not oriented in the same way. In addition, air bubbles can easily enter the metal during the pouring process, creating small holes inside the metal, known as "su" in the technical terminology. As a result, the finished ring is less durable than forged rings, and it is difficult to finish with high precision, which is a disadvantage.

Manufacturers and brands in the world famous for forged wedding rings.

The casting method is used as a manufacturing method by manufacturers around the world because it allows for a variety of designs, is easy to mass produce, and is cost-effective. On the other hand, Germany and Switzerland have the largest number of manufacturers using the forging method. There are also manufacturers in Japan that use the forging method. We would like to introduce some of the traditional manufacturers in Germany, Switzerland, and Japan who have adopted the forging method, in the hope that they will be helpful in familiarizing you with the forging method.

Who is recommended to have a forged wedding band?

As we have mentioned, wedding rings made by the forging process are highly durable, and their main feature is that they are more resistant to deformation and scratches than those made by casting. For this reason, they are recommended for people who want to wear them on their fingers all the time and not take them off when doing housework or raising children.
Also, forged wedding rings, which are made with a constant width and thickness due to the manufacturing process, are simple in shape. They are suitable for those who prefer a universal design that is not influenced by trends or age-related preferences, and that will never grow old.
