- In-House Core Manufacturing: Cores are produced internally, eliminating third-party variability and delays.
- Multiple Core Processes: Stahl supports both hot cured (shell) and cold cured (SO₂) core making to match application needs.
- Material Control: Flexibility in sand grain sizes and resin systems allows optimization for strength, finish, and removal.
- Engineering & DFM Support: Our engineering team collaborates early to ensure cores are designed for manufacturability and performance.
- Scalable Production: From low-volume programs to multi-million-part runs, processes remain consistent and repeatable.
For design engineers and procurement teams, these advantages translate into aluminum castings that meet performance requirements while minimizing production risk.
Welcome to Stahl Specialty Company – Serving the industry with high-quality aluminum castings since 1946.
Stahl’s mission is to become the world’s best aluminum casting supplier through innovation, profitable growth, and value creation for our customers, employees, and stakeholders.

- High-Volume Capability: Production volumes ranging from 500 to over 2,000,000 castings supported with consistent quality.
- Complex Geometry Expertise: Static pour processes paired with engineered cores support intricate internal features.
- Comprehensive In-House Capabilities:
- Tool design & engineering
- Core making (shell and SO₂)
- Heat treating
- Non-destructive testing (X-ray, dye penetrant, leak testing)
- Impregnation & assembly
- CMM inspection & laser scanning
By combining advanced core making with full-service aluminum casting operations, Stahl delivers reliable, production-ready components backed by proven manufacturing systems.
Founded in 1946 by Glenn W. Stahl, Stahl Specialty Company began as a regional aluminum foundry and has evolved into a state-of-the-art permanent mold aluminum casting and CNC machining operation. Over the decades, continuous investment in people, processes, and equipment has expanded our capabilities to meet modern manufacturing demands.
From our Kingsville, Missouri facility, Stahl produces aluminum castings ranging from two pounds to over 400 pounds. Our long-standing commitment to in-house core making has enabled us to support complex casting programs for industries that require precision, pressure-tight performance, and long-term reliability.
Today, Stahl’s history of innovation and process control continues to guide our approach to aluminum casting core making in Kingsville.
