Metal Forging vs. Metal Casting

 
Offshore Metal Casting
We have both metal forging and metal casting capabilities. Contact us for more information on which process is right for you.
Offshore Metal Forging
Sun Fast provides offshore sourcing for metal forging.

Offshore metal forging and metal casting are two processes that are commonly managed by international outsourcing companies when a business is unable to handle all aspects of a specific project. This can include finding skilled labor, access to specialized equipment and securing quality materials at a more affordable cost.

Using offshore metal casting provides a range of benefits for companies. One primary benefit is lower labor and raw material costs, which allows you to meet production demands while keeping expenses low. Companies that use an outsource manufacturing service for offshore metal forging also benefit from fewer operational concerns related to staffing and equipment maintenance and can expand their capabilities without having to purchase new equipment or a larger facility.

When you don’t have to worry about these and other day-to-day tasks, you can place more focus on strengthening and building your business. Learn more about our offshore metal forging and metal casting services or contact us to discuss your project.

Metal Casting and Metal Forging Methods

Metal forging and metal casting are the two most reliable and versatile methods for manufacturing metal parts and components for industrial, or heavy-duty applications. In many cases, the same part could be created using either metal casting or metal forging with roughly equal results. However, the two cannot be interchanged without significant revisions to part designs. Additionally, pricing can vary greatly from project to project; neither process will consistently be the more affordable option.

So, which method is better for your specific needs? Are there advantages to using offshore metal forging vs. casting, or vice versa?

Sun Fast International provides services for metal castingssteel forgings and aluminum forgings and can also offer unique insights into all three processes. Our experts will help you determine which method will work the best for your project requirement needs and find the right outsource manufacturing solution for your project.

What are Custom Metal Castings?

Metal casting occurs when molten metal is poured or injected into a custom-made mold. After the metal cools and hardens the finalized metal part shape is then ready to be finished. This can be accomplished through additional machining, and other processing techniques that are used to achieve desired tolerances and finishes. 

There are several different methods that are available for casting a part. The most popular methods include, die, sand, and investment casting. Each method uses a slightly different process but delivers the same results. The casting method used depends on the metal or alloy being cast, and the dimensions and geometry of the part design, among other factors.  

Because molten metal flows much like a liquid and can completely fill all areas of an intricate mold shape, metal casting is the preferred process for creating complex metal parts. Metal casting is also far better suited for making parts that require internal cavities. There is essentially no upper or lower size limit for cast parts, making it the ideal method for small to very large parts.

Metal Casting Advantages 

Metal casting provides several distinct industrial advantages, some of which include:

  • Accepts higher tolerances for more detailed part designs
  • Creates closer to net-shape parts that require less secondary machining/processing
  • Nearly always lighter than otherwise-identical forged parts
  • Easier and less time-consuming modification of part designs and accompanying molds 

Metal Casting Disadvantages

Metal casting is not always the preferred method for creating parts, some of the disadvantages include:

  • Often exhibit more surface porosity than forged parts and may contain unintentional voids
  • Not as tough as forged parts (cannot withstand as much pressure or frequency of impact)
  • Requires more operator monitoring and interaction to maintain quality and prevent defects

What are Custom Metal Forgings?

When creating custom steel forgings or aluminum forgings, massive compressive forces are used to shape a solid piece of metal into its desired shape. The raw metal is forced under thousands of pounds of pressure into a die that gives the part its shape (similar to a mold used for casting). In addition, post-forging parts often require a good deal of additional machining or other processing to reach the desired final shape, dimensions, or finish.

There are several different classifications of forging that can be used. The choice is based on process temperatures (hot or cold forging) and the type of die utilized (open- or closed-die forging). The forging method used depends on the metal or alloy being worked, and the application(s) for which the parts will be used.

The high pressure that is used within the steel forgings or aluminum forgings process causes metallurgical recrystallization and grain refinement, which conforms to the shape of the part. This results in mechanically stronger parts with greater impact strength, shear strength, and wear resistance.

Metal Forging Advantages 

Metal forging provides several distinct industrial advantages, some of which include: 

  • Better structural integrity and increased mechanical strength due to the altered grain structure
  • Cost savings due to less material scrap and reduced labor requirements
  • Forging process eliminates surface porosity, cavities/voids, and discontinuities
  • Greater reliability and consistency in ductility, known yields, and increased strength 

Metal Forging Disadvantages

Metal forging is not always the preferred method for creating parts, some of the disadvantages include:

  • Tight tolerances are difficult to acquire due to the nature of the process
  • Numerous secondary processes may be required to meet final design specifications
  • Forging process limits the intricacy of shapes that can be produced
