Metal Castings 101: Why They’re the Backbone of Manufacturing—and How SanCo Sales Can Help You Source Them Without the Usual Headaches
Metal castings are everywhere.
In your car. Inside your washing machine. Holding up bridges. Powering factories. They’re the unsung heroes of modern manufacturing—hidden behind layers of paint, insulation, and branding—but they’re the reason everything from engines to elevators actually work.
If you’re looking for high-quality metal castings and trying to figure out who to trust, you’re in the right place. SanCo Sales isn’t a foundry. We’re better—we’re your manufacturing matchmaker. Think of us as the go-to crew that connects companies like yours with the right metal casting suppliers (yes, both domestic and overseas). And we make sure things get done right the first time.
Let’s dive in.
⚙️ What Are Metal Castings, Exactly?
At its core, metal casting is a process where molten metal is poured into a mold to form a specific shape as it cools and hardens. It’s been around for literally thousands of years because it works. The concept is simple. The results? Game-changing.
Whether it’s iron, steel, aluminum, brass, bronze, or any other alloy, casting is how complex, heavy-duty parts are created at scale without needing to machine everything from solid blocks. (Your CNC guys just breathed a sigh of relief.) Need more? All things castings here.
🏭 What Types of Casting Processes Are Out There?
You’re not just here for a history lesson—you want to make the right sourcing decision. That starts with understanding your options. Here are some common types of metal casting processes SanCo can help you source:
1. Sand Casting
- Perfect for short runs or large, heavy parts.
- Highly flexible and cost-effective.
- Works with a range of metals (iron, steel, aluminum, bronze, etc.).
2. Investment Casting
- Super high detail and great surface finish.
- Ideal for complex geometries and precision.
- Often used in aerospace and medical industries.
3. Die Casting
- High-volume production.
- Excellent dimensional accuracy.
- Typically limited to non-ferrous metals like aluminum and zinc.
4. Centrifugal Casting
- Great for cylindrical parts like pipes and sleeves.
- Produces dense, high-integrity sections.
5. Permanent Mold Casting
- Reusable molds = better repeatability.
- Faster cycle times than sand casting.
Don’t worry if you’re not sure which one you need. That’s literally what we do—match the right part with the right process and the right foundry. We have you covered with aluminum castings as well!
🧠 Why Metal Castings Are Still a Big Deal in 2025
In an age of 3D printing and AI-driven everything, you’d think castings might be obsolete. But nope. They’re more important than ever. Why?
Because castings still:
- Offer unmatched strength and durability.
- Support high-volume production.
- Handle high-stress and high-heat environments.
- Deliver cost savings at scale.
That part on your desk that’s machined from billet? A casting could’ve done the same job for half the cost and 5x the volume. (But hey, keep that paperweight.)
🤝 How SanCo Sales Takes the Guesswork Out of Sourcing Metal Castings
Okay, real talk.
Sourcing metal castings can suck. It’s messy, slow, and often full of mystery quotes, ghosted emails, and suppliers who swear they can “do everything” but disappear when you ask for material certs.
We fix that.
At SanCo, we represent a network of top-tier foundries—both in the U.S. and internationally—who specialize in different casting processes and materials. We already know who’s good at what and who ships on time. We know who makes a mean 500-pound ductile iron housing and who crushes 5,000-part aluminum production runs.
Here’s What You Get:
- ✅ Vetted suppliers, not a Google search headache
- ✅ One contact (us) who gets the job done
- ✅ Options based on your priorities (price, timeline, quality, etc.)
- ✅ Domestic AND overseas sourcing—with U.S. warehousing if needed
We’re like the secret weapon your sourcing team didn’t know it needed. Until now.
🧩 What Can Be Made with Metal Castings?
Short answer? Basically everything. But here’s a taste of the projects we’ve helped bring to life:
- Large ductile iron gear housings
- Complex stainless steel investment cast valves
- High-volume aluminum brackets
- Bronze pump components
- Steel impellers
- Custom OEM parts for mining, agriculture, defense, and more
If you can draw it, spec it, or dream it—we can probably get it cast.
🔍 What Should You Watch Out For When Sourcing Castings?
Let’s call out the red flags before they wreck your project:
- ❌ Quoting without DFM input (design for manufacturability)
- ❌ Ignoring tolerances that are outside the process capability
- ❌ Assuming all foundries are the same (spoiler: they’re not)
- ❌ Believing you’ll get 6-week lead times for a 2,000-piece order without any tooling
Pro tip: Talk to SanCo early in the process. We’ll give you realistic timelines, appropriate process selection, and probably a couple of sourcing tips that’ll save your butt down the road.
🕒 How Fast Can You Get Castings?
Depends on the process and location—but here’s a rough cheat sheet:
| Casting Type | Tooling Lead Time | Production Lead Time |
| Sand Casting | 2–4 weeks | 4–6 weeks |
| Investment Casting | 3–6 weeks | 6–8 weeks |
| Die Casting | 4–8 weeks | 5–9 weeks |
Need it faster? We’ll do our best. We’ve got partners who can hustle when the project really matters.
