If you&#;re not entirely sure which forging materials are right for your industry or application, you don&#;t need to worry. We will work closely with you to find a unique solution. Our engineering and design capabilities enable us to meet a wide variety of needs.

Regardless of the forging materials used,  forged components are far superior to cast products. Forged steel, titanium, carbon alloys and superalloys will always outperform cast materials. A research paper from the University of Toledo comparing casting and forging concluded:

• The tensile strength of forged parts is 26% higher than that of cast parts.
• The fatigue strength of forged parts is 37% higher than that of cast parts.
• Cast iron exhibits only 66% of the yield strength of forged steel.
• Forged parts exhibit a 58% reduction in area when pulled to failure, while cast parts exhibit a 6% reduction in area.

The results speak for themselves. Even in failure, forged parts and components will always be stronger and more reliable than their cast counterparts.

Whatever your industry and application, we will find the perfect forging materials to create custom closed-die forging solutions that meet your unique specifications. If you have any questions or concerns about forging materials, call or contact Canton Drop Forge.

Open die forging is a metalworking process that involves shaping a heated metal billet between two flat dies without completely enclosing the material. This process can create a wide variety of shapes and sizes, making it popular in the aerospace, automotive, and defense industries. Here are some common questions and answers about open die forging.

All You Need to Know About Open Die Forging

What Is Open Die Forging?

Open die forging is a metalworking process that uses flat dies to shape a heated metal billet into a desired form.  

What Materials Are Commonly Used?

Open die forging can be used with a variety of materials, including steel, aluminum, copper, titanium, and nickel alloys. The type of material used varies depending on the desired properties of the final product, such as strength, weight, and durability.

What Are the Advantages?

One of the main advantages of open die forging is the ability to produce custom shapes and sizes with precise dimensions. This makes it ideal for creating unique parts for specialized applications. Open die forging also produces a stronger final product compared to other manufacturing processes, such as casting.

What Are the Limitations?

Open die forging can be more time-consuming and labor-intensive than other manufacturing processes, such as casting or machining. Additionally, the size of the final product is limited by the size of the equipment used in the process.

How Is Open Die Forging Different From Closed Die Forging?

Impression forging, also known as closed die forging, uses a set of dies that completely enclose the metal billet, creating a precise shape with little to no waste material. Open die forging, on the other hand, uses flat dies that only shape the metal in certain areas, resulting in more material waste but greater flexibility in shaping.

Hence, the main difference between open die forging and closed die forging is the level of enclosure around the metal during the forging process.  

What Are Some Common Applications?

Open die forging is used in a wide variety of industries, including aerospace, defense, automotive, and construction. Common applications include gears, shafts, axles, connecting rods, and other specialized parts that require high strength and durability.

What Factors Affect the Quality of the Final Product?

The quality of the final product in open die forging is affected by several factors, including the temperature of the metal, the pressure applied during forging, the cooling rate, and the skill of the operator. Proper control of these factors is essential for producing a high-quality final product.

What Are Some of the Advantages of Using Open Die Forging for Large Parts?

Open die forging is particularly well-suited for creating large parts that require high strength and durability, as it allows for precise shaping of the metal without compromising its structural integrity. In addition, open die forging can help reduce material waste and produce parts with a better surface finish.

What Are the Most Common Defects That Can Occur During the Process?

Some common defects that can occur during open die forging include surface cracks, internal voids, and dimensional inconsistencies. These defects can be minimized by careful control of the forging process and thorough inspection of the final product.

What Are Some of the Challenges Associated with Open Die Forging?

One of the main challenges of open die forging is maintaining consistent temperature and pressure throughout the forging process, particularly for large or complex parts. In addition, open die forging requires skilled operators who are able to carefully control the equipment and produce high-quality parts.

Can Open Die Forging Be Used for Both Small and Large Parts?

Yes, open die forging can be used for both small and large parts, making it a versatile process. The size of the final product is limited by the size of the equipment used in the process, but many open die forging facilities have the competence to produce a wide range of sizes.

How Does Open Die Forging Compare to Other Metalworking Processes, Such as Casting and Machining?

Open die forging is typically stronger and more durable than cast or machined parts, due to the fact that the metal is compressed and shaped during the forging process. However, open die forging can be more time-consuming and labor-intensive than casting or machining, particularly for complex shapes or large parts.

What Types of Metals Are Commonly Forged Using the Open Die Forging Process?

Open die forging can be used with a variety of metals, including steel, aluminum, copper, brass, titanium, and nickel alloys. The type of metal used vary on the desired properties of the final product, such as strength, weight, and corrosion resistance.

What Is the Typical Lead Time for Open Die Forging Projects?

The lead time for open die forging projects can vary depending on the intricacy of the part and the volume of the order. However, it typically takes several weeks or even months to complete a large open die forging project, as the process involves multiple stages of heating, shaping, and cooling.

What Are Some of the Safety Considerations Associated With Open Die Forging?

Open die forging can be a hazardous process, as it involves high temperatures, heavy equipment, and the potential for flying debris. Safety measures such as protective gear, safety barriers, and regular equipment maintenance are essential for preventing accidents and injuries in the workplace.  

What Are Some of the Key Advantages of Open Die Forging Compared to Other Metalworking Processes?

Open die forging offers several advantages over other metalworking processes, including the ability to create custom shapes and sizes, greater strength and durability, and a finer grain structure. Additionally, open die forging can produce parts with a better surface finish and fewer defects than other processes, such as casting.

How Does the Temperature of the Metal Affect the Open Die Forging Process?

The temperature of the metal is a critical factor in the open die forging process. If the metal is too cold, it will be difficult to shape and may crack or fracture. If the metal is too hot, it may become too soft and lose its structural integrity. Maintaining a consistent temperature throughout the forging process is essential for producing a high-quality final product.

What Are Among the Common Materials Used for Open Die Forging in the Aerospace Industry?

In the aerospace industry, open die forging is commonly used with materials such as titanium, aluminum, and nickel alloys. These materials provide high strength-to-weight ratios and excellent corrosion resistance, making them ideal for aerospace applications.
