Metal Forging Services: Strength, Process, and When to Forge

Metal forging services shape metal by compressive force, aligning the grain flow to create parts that are stronger and more fatigue-resistant than machined or cast equivalents. For crankshafts, hubs, flanges, and structural links, forging is often the right answer. This guide covers closed-die vs. open-die forging, when to forge vs. machine or cast, and how to brief a forging partner.

Closed-Die vs. Open-Die Forging

Closed-die forging squeezes heated metal in a precision die for near-net, repeatable shapes at volume. Open-die forging is for large, simple, lower-volume blocks and rings. Our forging line covers both, plus hot and warm processes.

Why Forge Instead of Machine or Cast

Forging’s grain flow follows the part shape, boosting strength and fatigue life where cast or machined stock can’t. Investment casting wins on complex detail; CNC machining wins on low volume and tolerance. Our fabrication team helps you pick.

Materials and Tolerances

Carbon, alloy, and stainless steels, plus aluminum and titanium, all forge well. As-forged tolerances are coarse; critical faces are machined after forging via forge+machine combinations. Heat treatment tunes strength.

When Forging Pays Off

1. Strength or fatigue is critical → forge it.
2. High volume of a simple shape → closed-die.
3. Large, low-volume block → open-die.
4. Need one supplier → forge, machine, and finish together.

FAQ

Forging or casting?
Forging for strength/fatigue; casting for complex detail at volume.

Can you machine after forging?
Yes—critical faces are CNC-machined for fit and seal.

What finishes apply?
Zinc plating, powder coat, and passivation are common.
