As reshoring efforts accelerate, forging companies are finding OEM rebuilds to be a strategic solution for boosting domestic capacity

Reshoring is gaining momentum as shifting global economic conditions are forcing manufacturers to reevaluate their supply chains, and forging operations are squarely in the spotlight. Aerospace, defense, transportation, and heavy mobility are leading the charge, each relying on a steady flow of high-quality forged components to support growth, innovation, and national security.

At the same time, policy and pricing pressures are reshaping the competitive landscape. Tariffs on steel, aluminum, and other metals have raised the cost of imports, making domestic forging operations more competitive. In addition, "Buy America" provisions and other government trade measures are incentivizing companies to source domestically, both to remain compliant with regulations and to reduce the uncertainty that comes with fluctuating tariffs and duties on foreign goods.

The demand to reshore forging also reflects a fast-moving and unpredictable global environment where conflicts and rising tensions are requiring the U.S. to deepen its investment in military ordnance.

Forged components are found in virtually every defense implement, from rifle triggers to nuclear submarine drive shafts. Heavy tanks, missiles, armored personnel carriers, shells, and other heavy artillery require forged components.

Forging is also a core component for a multitude of parts from engine mounts, brackets, beams, shafts, landing gear cylinders, and struts and wheels in military aircraft and spacecraft.

With these pressures increasing demand, manufacturers are now facing longer lead times for new or custom forging presses and hammers. Fortunately, manufacturers have more than one path forward and investing in brand-new equipment is not the only solution.

Rebuilt Forging Equipment
Today, many forgers are turning to the revitalization of idle or underutilized machinery, commissioning complete rebuilds from Original Equipment Manufacturers (OEMs). This approach allows production to scale up far more quickly while new forging equipment is still on order.

"Rebuilding is often the fastest, most economical means to get worn or mothballed equipment back into production when purchasing new equipment may not be feasible," says Bill Goodwin, Vice President of Sales, Ajax-CECO-Erie Press (ACE), the largest forging equipment supplier in North America, founded in 1875. The company has over a century of experience in custom designing and building presses and forging machines spanning horizontal, vertical, mechanical, hammer, and hydraulic forging presses for a variety of applications.

According to Goodwin, rebuilding entails removing all a machine's parts and repairing or replacing them with OEM components to return them to manufacturer specifications. Recognizing that the high-impact nature of forging takes its toll on parts over time, a rebuild typically includes replacing high-wear items such as bearings, bushings, seals, and liners and inspecting and repairing the frame.

Often more efficient and cost-effective than purchasing new forging equipment, rebuilding is ideal for quickly getting equipment operational again, often in as little as just a few months.

Rebuilding can even be an effective option for older forging equipment, including updates and modifications for new product lines or restoration to original specifications. A rebuild can also increase the production capacity of slow and inefficient equipment.

Optimizing the Rebuild
When electing to rebuild, manufacturers can choose to contact the OEM to rebuild the equipment or contract with a third-party rebuilder. The decision is significant, given the need for a complete, dependable rebuild that will perform as expected for many years.

Rebuilders often use a reverse engineering process to create their parts or have them machined at local CNC shops. Although this approach may work in the short term to "get equipment up and running," it ignores the long-term view. Even rebuilders with experience working on various other types of equipment, such as stamping presses or injecting molding machines, may only partially appreciate the forces exerted during the forging operation.

Moreover, critical engineering design data is lost when an independent rebuilder reverse-engineers a part, resulting in inferior part construction and premature wear or component failure.

"Often they are rebuilding a machine without truly understanding the original design intent or the loads that will be placed on the parts and equipment," says Goodwin.

As an alternative, it can be advantageous to work with the OEM for an equipment rebuild. The OEM has the original design specifications, critical materials, and clearance specifications to jump on rebuilds and quickly finish the work.

A vast range of information is required for a quality rebuild, such as critical data on high-wear parts, the material grade of the steel, the heat-treating process utilized, and the required clearances used in that forger's engineering.

When working with the OEM, a rebuild is not limited to restoring the original design capabilities to today's standards but can also include significant automation upgrades.

"A rebuild can be approached in several ways," explains Goodwin. "The forging equipment can be sent to us for rebuilding; we can send repair personnel to the manufacturer's facility to rebuild equipment on-site, or we can supervise a rebuild by their maintenance staff."

Whichever option a manufacturer selects, revitalizing old and unutilized forging equipment with an OEM can reclaim much needed capabilities from existing and dormant assets in a timely and cost-effective manner to meet increased demand for domestic forging capacity in the years to come.
