Hey there, if you’ve ever wondered about the guts of an airplane or a rocket—those parts that hold up under insane heat, pressure, and constant stress—let me cut to the chase: closed die forgings are basically the unsung heroes of aerospace. As a third-gen closed die forgings supplier, I get asked this question all the time from aerospace engineers, contract manufacturers, and even hobbyists tinkering with small satellite components. “Can closed die forgings actually work for aerospace?” The short answer? Hell yeah, and here’s why—no stuffy textbook jargon, just real talk from someone who’s been making these parts for 20+ years. Closed Die Forgings
First off, let’s skip the boring explanation of what closed die forging is (you can Google that if you’re new here, but I’ll keep it quick): it’s when you heat metal (usually alloys like titanium, aluminum, or steel) until it’s squishy, then hammer it between two custom steel dies shaped exactly like the part you need. The metal flows into every nook and cranny of the die, so you get a part that’s way denser, stronger, and more consistent than a machined one from a solid block of metal. For aerospace, that “consistent and strong” stuff isn’t a nice-to-have—it’s non-negotiable. A wing flap hinge? It can’t crack mid-flight. A jet engine turbine blade? It has to spin at 10,000 rpm at 1,700°F without bending. Closed die forging delivers that reliability because it eliminates weak points—like voids or gaps—that you sometimes get with casting or machining a solid chunk. I’ve seen so many aerospace projects ditch cast parts after a single stress test failure, only to switch to forgings and never look back.
Wait, but hold on—people still ask, “Why not other methods?” Casting’s cheaper, right? Yeah, for simple parts, but aerospace needs parts that perform in extreme conditions. Casting can have porosity (tiny air bubbles) that, when exposed to repeated stress, turn into cracks. We test our forgings with ultrasonic inspection every single time to make sure there’s zero porosity. Machining from a billet works, but you waste like 70% of the metal as scrap—for a $10,000 titanium billet, that’s a huge cost hit for aerospace, where every pound saved translates to thousands in fuel savings over a plane’s life. Closed die forgings use almost all the metal you put into the die, so it’s way more efficient, and the grain structure of the metal flows exactly with the part’s shape, making it stronger where it needs to be. That’s a game-changer for weight, too—less metal means less lift needed, more payload, longer range. Aerospace engineers live for that.
Let’s get specific with real aerospace uses, not just vague “parts.” We supply a lot of the parts for regional jet landing gear components. Landing gear has to support the entire weight of a 70-ton plane on takeoff and landing, withstand hard impacts, and resist corrosion from runway chemicals and salt air. Closed die forged alloy steel parts here are the only way to go—they don’t fail under those extreme loads. We also do a lot of titanium forgings for small satellite frames. Satellites get blasted with vibration during launch, extreme temperature swings in space, and micro-meteoroid impacts. Titanium forgings’ high strength-to-weight ratio makes them perfect—they’re light enough to launch without adding extra fuel, and tough enough to survive 15+ years in orbit. I had a customer last year who was using a 3D-printed aluminum bracket for a CubeSat, but it cracked during vibration testing. Switched to a closed die forged aluminum part, and it passed with flying colors. No more failures, no more redesign costs.
But wait, is there a catch? Yeah, closed die forging isn’t for every part. If you need a super small, simple bracket, or a custom shape that’s one-off, it’s not the cheapest route—you have to make the custom dies, which can cost a few thousand bucks, and that’s not worth it for a single part. But for aerospace, where you’re making hundreds or thousands of identical parts for a fleet of planes or satellites, the die cost spreads out fast, and the long-term reliability and cost savings (from less scrap, less maintenance, fewer part failures) blow other methods out of the water. Also, we work closely with aerospace engineers from the start of a project—we don’t just drop off a box of parts and ghost. We help them design parts that work with closed die forging, so they get the strongest, most cost-effective part possible without overengineering.
Another thing people don’t talk about: aerospace parts have super strict quality standards—AS9100, NADCAP, you name it. We’ve been AS9100 certified for 18 years, and every forging leaves our shop with full traceability. We track every batch of metal, every heat cycle, every inspection result—if something goes wrong, we can find exactly where it happened, no excuses. That’s non-negotiable for aerospace, where a part failure can lead to grounded planes, lost revenue, or even safety issues. When we supply parts, our customers know they’re getting a part that’s been tested to meet or exceed those aerospace standards, not just a random metal chunk that looks right.
I get it—if you’re not in the aerospace industry, this stuff might sound overcomplicated. But let’s put it in perspective: a commercial jet has about a million parts, and a huge percentage of the high-stress ones are closed die forgings. From the engine mounts that keep the turbine attached to the wing, to the control surfaces that make the plane turn, to the landing gear struts that hold the whole thing up—forgings are everywhere. Even rockets, which are all about weight savings, use titanium forgings for their fuel lines and engine components. The SpaceX Falcon 9’s Merlin engine has parts that we make similar forgings for—strong enough to handle the pressure of rocket fuel burning at 3,000 psi, light enough to get the rocket to orbit.
Now, I know what some of you are thinking: “What about new tech like additive manufacturing?” Yeah, 3D printing is cool, but it’s still catching up to forgings for high-stress aerospace parts. We’ve had aerospace customers test 3D printed parts, but most of them come back to us because even the best 3D printed parts have inconsistent grain structure and can’t match the fatigue resistance of forgings. For parts that will see thousands of flight cycles, fatigue is the big killer—how many times can a part bend and flex before it breaks. Forgings handle fatigue way better because their grain lines follow the part’s shape, so there’s no weak point where cracks can start. That’s not something 3D printing has nailed yet, especially for the strict aerospace specs.
So, to circle back to the original question: Can closed die forgings be used in aerospace? Absolutely—they’ve been used for decades, and they’re still the go-to for the parts that matter most. Are they the right choice for every aerospace part? No, but for high-stress, high-demand components, they’re the most reliable, cost-effective option out there.
If you’re an aerospace engineer, procurement manager, or someone working on a project that needs parts that can take the heat, the pressure, and the constant stress—hit me up. I don’t do hard sells, I just do real talk about what works, what doesn’t, and how we can help you get the parts you need without the headaches. We can walk through your design, talk about specs, and give you a transparent quote—no fine print, no surprise costs. Let’s make parts that fly, not parts that fail.
