Guideline on Selecting Drop Forging or Machining

When you have a metal component put into production, there may be several metalworking processes to choose from. Each type of metalworking process has its own pros and cons, depending on your needs, so, it is important to understand which one is better when selecting drop forging or machining.

Below is the guide for a better idea on selecting Drop Forging or Machining:

Drop Forging Should be Selected.

Drop forging offers many unique advantages when compared to machining, especially in demanding industrial applications. If you are worried about your parts failing prematurely, or your application requires maximum strength and durability, drop forging is likely better suited to your needs.

*To improve part integrity
Drop forging provides a higher level of structural integrity than any other metalworking process. By eliminating structural voids that can weaken parts, drop forging provides a level of uniformity to help maximize part performance.

*To keep grain flow intact
During machining, grain ends are exposed, making parts more susceptible to weakening and cracking. Drop forging refines and strengthens parts by keeping the grain flow intact, helping to strengthen transition points and prevent premature failures.

*For material savings
Because it requires less starting material to create a drop forged part, closed die forging can help reduce waste and material costs. When you turn a product from bar, the corner stock is lost, but you are still required to pay for the excess material. With drop forging process, your part is shaped by the dies, significantly reducing material waste.

Machining Should be Selected.


While drop forging offers many advantages in part strength and longevity, it is not necessary for many lower-impact applications. If your parts will not be subject to ongoing wear and tear, machining will likely be an effective and affordable solution for your needs.

*For simpler applications
In lower-impact applications, strong transition points are likely not your top priority. Parts machined from bar are typically sufficient if you are planning to use your parts in less demanding environments.

*If the budget is tight
Drop forging can be a pricier alternative to machining, and although it offers many benefits, these benefits might not outweigh the costs in some situations. If the longevity and material savings from drop forging do not compensate for the price tag, machining might make more sense for your application.
