Forging processes are widely used for shaping metal parts. There exist different types of metal forging processes, including cold forging, open die forging, and others. Each process is unique and used for specific applications.
Before choosing Metal Forgings for your manufacturing hub, you must educate yourself about the types of forging processes. To help you out, we have provided a guide, explaining the different techniques. Let’s take a look at the details given below.
Impression Die Forging
Impression die forging, also known as Closed Die Forging involves using dies that enclose the base material. Using the right die helps you to transform metal parts into desired shapes. One thing about impression die forging is that it requires a higher compressive force. It is important to ensure the die fills the cavities and forms the complete part.
Impression die forging has some advantages which makes it a popular choice among industries. These include:
- Resistance to impact
- High production rates
- Results in less metal waste
- Produces tougher and more durable metal parts
Cold Forging
With Cold Metal Forgings, you can design and create a wide range of metal components. The good thing about this process is that it results in excellent finish quality. Plus, it offers greater dimension tolerance.
Cold precision forging is different from other forging processes. This is because it doesn’t require heat to shape metal parts. Instead of higher temperatures, the process is carried out in lower temperatures. With the help of this process, you can make parts like stems, shafts, cup-shaped geometries, and odd configurations.
The primary advantages of cold forging include:
- Produces very little metal waste
- Offers tight tolerances
- Results in excellent surface finish quality
- Dies lasts longer than in heat forging
Open Die Forging
Open Die Forging is another popular forging method used for making metal parts. It is also known as hammersmith forging which involves direct force to shape metal pieces.
In open Die Forging, you use a hammer to deform a workpiece metal. It involves using two flat dies that don’t enclose the material like in other forging methods. With open-die forging, you can shape metals up to 150 tons. Well, this is what makes it a suitable choice for making heavy metal parts.
The main advantages include the following:
- Results in finer grain size
- Reduces chances of voids
- Extends part life
- Offers continuous grain flow
- Enhanced fatigue resistance
Seamless Rolled Ring Forging
In seamless rolled ring forging, you create a hole in a thick metal piece. After that you squeeze and roll it into a thin ring, preparing it for the forging processes. Due to the steps involved, it makes a great choice for making ring diameters.
Unlike other forging methods, rolled ring forging uses curved dies as it makes it easier to form ring-shaped parts.
Some of the advantages include:
- Ensures controlled directional flow
- Enhanced structural integrity
- Removes porosity, and inclusions
Whether you choose Die Forging or any other forging process, you must make sure that it aligns with your requirements. Unless that is fulfilled, you cannot get the most out of the forging process.
