What are the largest metal casting companies?
Many buyers look for the biggest names in casting, hoping that size guarantees quality.
The largest metal casting companies serve industries like aerospace, automotive, energy, and defense.
Here are the leading players in 2025:
| Company Name | Country | Strengths |
|---|---|---|
| Precision Castparts Corp (PCC) | USA | Aerospace-grade investment castings |
| Arconic Corporation | USA | Structural aluminum and titanium castings |
| Impro Precision | China | Automotive, hydraulic, and agricultural castings |
| Bharat Forge | India | Large steel castings and forgings |
| Alcoa Corporation | USA | Lightweight alloy castings for aerospace |
| Kimura Foundry | Japan | Rapid prototyping via 3D sand printing |
At Prime, we don’t compete in size—but in precision. Our ISO-certified casting lines serve custom orders with global delivery and fast lead times.
Who is the largest casting producer in the world?
Casting production isn’t just about big factories—it’s about volume, exports, and industry diversity.
China remains the largest casting producer globally, contributing over 45% of the world's casting output.
This includes steel, iron, aluminum, zinc, and specialty alloys.
According to the American Foundry Society, China’s leadership is driven by its low labor costs, abundant materials, and growing export base.
However, not all Chinese suppliers offer consistent quality. That’s where exporters like Prime stand out—with 20+ years of international casting expertise.
What is a factory that specializes in making castings?
Buyers often confuse foundries with machine shops. Each serves a unique role in the production chain.
A foundry is a specialized factory that melts and pours metal into molds to produce casting components.
Foundries usually offer:
- Sand casting
- Die casting
- Investment casting
- Shell molding
- Permanent mold casting
At Prime, we operate full-service casting lines including mold design, melting, pouring, cooling, finishing, and custom packaging. We also integrate post-casting CNC machining for tighter tolerance parts.

What is the difference between foundry and metal casting?
These terms often confuse buyers, especially new sourcing managers.
"Metal casting" is the process. "Foundry" is the place where it happens.
Here’s a clearer breakdown:
| Term | Definition | Example |
|---|---|---|
| Metal Casting | The act of pouring molten metal into a mold | Investment casting of turbine blades |
| Foundry | The factory that performs casting | Prime’s ISO-certified foundry in Shandong, China |
Some factories only offer machining or finishing. Others, like Prime, handle casting + machining + assembly, offering one-stop service.
