Custom Forging

custom forgingIt’s no wonder metal forging has been practiced since the Bronze Age. The forging process renders metals stronger and longer lasting than their non-forged counterparts. Greater component strength and longer lifespan are qualities that potentially improve an operation’s productivity and profitability.

For over 50 years, Trenton Forging has served as a leading innovator in custom forging across a wide array of industries and applications.

The Forging Process

Forging employs various hammer-like tools or weights to strike red-hot steel and other metals to compress them. Repeated compression reorganizes the composition of the metal in advantageous ways. It alters the grain flow to align with the ultimate shape of the product, increasing its overall strength. It also eliminates air bubbles that can compromise integrity.

For smaller applications, a hand hammer may be used. Larger applications employ hydraulic machines that raise and drop heavy weights repeatedly onto the hot drop forged steel.

Closed-die custom forging is the preferred method for components with complex configurations or varying wall thicknesses. A type of mold, called a die, pushes into the metal, compressing and forming it into the desired shape. Trenton Forging is proud to be an industry leader in Closed die forging.


custom steel forgingTrenton enjoys being on the cutting edge of the market. We are always eager to incorporate new technologies in all aspects of advanced custom steel forging.

3D Laser Scanning – Our state-of-the-art scanner can map and replicate your existing part in a fraction of the time required by conventional digitizing. Components that call for custom forging can be complex. No matter how intricate the part, specialized sensors and light beams calculate thousands of coordinates per second, generating a new version of your product within minutes.

Laser-scanning technology facilitates simulation and reverse engineering, enabling you to correct flaws or make design changes.

3D Printing – If your operation needs a prototype for testing or design purposes, nothing compares to the fast turnaround of 3D printing. Your drawings and specifications can become a quality prototype in just a day or two.

In-House Capabilities – As an important part of our full-service role in custom forging, Trenton has developed in-house facilities for tool-and-die forging and die welding. Even Trenton’s electrical power is supplied by our own dedicated sub-station.

As we increase our capacity and minimize our overhead, we are happy to pass the savings on to you. This is just one of the ways we work to maintain the fastest product-to-market timeline in the industry.


Whatever brings you to Trenton Forging, we will work with you to match your product needs with our expertise. From chisel bits and automobile hinges to geodesic dome cones, we routinely provide custom forging for clients in agricultural, construction, military, automotive and marine industries, to name a few. Here are two examples of industries Trenton routinely serves:

Agriculture – When Trenton entered the agriculture industry as a supplier of custom forgings, we expected it to be challenging. Agriculture is subject to high downtime rates due to frequent equipment damage and repair. Tractors and combines are workhorses, and the durability of their components is essential.

Trenton relishes the opportunity to develop creative solutions that boost component durability and reduce downtime for our clients.

Railroad – The strength and reliability custom forging offers is essential to components used in the railroad industry. When we forge railroad brake pins or track-switch irons, as with many forged steel applications, we understand safety is part of the equation. Trenton aims to produce components with the high degree of structural integrity and dependability our clients’ diverse applications require.
