Trenton Forging FAQ’s

Q: What is a Forging?
A: See our video here: “How a Forging is Made”


Q: Why is a forging superior to other processes such as casting or parts machined from billet?
A: Heating steel billets and forming them in a way that retains and improves the internal grain structure of the material create a forging. We produce a product that is superior in strength and longevity to a casting, fabrication, or machined part and we can often do it in a lighter and more efficient package.

Q: What materials can we forge?
A: At Trenton we can forge steel and all of its alloys as well as stainless steel.


Q: Why don’t you forge aluminum?
A: We use induction heating to get our raw material to proper forging temperature. Even though it will heat aluminum, we cannot keep it at proper forging temperature throughout the hammer forging process. Aluminum forgings would best be produced on a forging press. Trenton doesn’t currently employ presses but that capability may be something we will have at our disposal in the future.


Q: What type of forging equipment does Trenton Forging utilize?
A: We run air-lift, gravity-drop style hammers using closed impression dies to form our product. Plans for adding forging presses are in the works.


Q: Does Trenton Forging have a size limit?
A: using a round-bar billet of approximately 2.5″ or less we can definitely handle the project. This usually equates to a size limit of about 15-20 lbs.
