Air-lift, gravity-drop style hammers and the use of closed-impression dies is what Trenton Forging Company’s “forging” operations are comprised of. Working with steel, stainless, and steel alloys, we heat and form billets in this way that we can ensure product integrity, maximized strength, longevity, and engineered grain structure of each custom steel forging.
The scope of our close die forging process includes:
- Steel, stainless steel, and steel alloys
- .01 – 15 pounds
- Maximum length of 24”
- Cross-sections of 2.875”and smaller
- Draft angles of 7 degrees or greater
- Radii 0.060” and larger
Whether as small as one-tenth of a pound in weight, or as large as fifteen pounds, we are dedicated to creating steel forging products that exceed your wildest expectations.
How do we do it? Well, our process of closed-impression die forging moves heated steel between two custom-machined dies, forcing it to take the shape of the voids within. This process of drop hammer forging reduces the cost of scrap that is common with billet machining or other subtractive-manufacturing processes.
By forming a near-net shape part to begin with, we can eliminate significant post-processing. Not only is this more cost-effective, but heating steel billets and forming them in a way that retains or improves the grain structure (that the raw material was original drawn with) will produce a product that is far superior in strength and longevity – as opposed to a casting, fabrication, or machined part. In most cases, this leads to a lighter and more efficient package.
