Who We Are
GD Casting Group was formed through the merger of Dart Casting and General Die Casters—two legacy leaders in aluminum high-pressure die casting.
With combined roots dating back to 1957, we’ve built a powerhouse in U.S. manufacturing, offering end-to-end solutions from tooling design to final assembly. Our broad industry experience and deep technical know-how make us the go-to partner for complex, precision aluminum components.
With over 30 die casting cells and 25 CNC machines, we offer full-service capabilities from casting to assembly—delivering where others can’t.
High-Performance Tooling. Proven Results.
Our expert die cast engineers use MAGMA flow simulation to design precision tools that consistently produce compliant parts—shot after shot.
With optimized gating, cooling, and venting, our tools outperform and outlast the competition, protecting your investment and your production schedule.
With longer tool life, faster cycle times, and fewer casting issues, GD Casting delivers the performance—and ROI—that buyers expect.
What started as a single- die machine shop in Illinois and a quality-driven operation in Ohio has now become one unified team—built to solve complex die casting challenges with precision, speed, and dedication.
With over 30 die casting cells and 25 CNC machines, we offer full-service capabilities from casting to assembly—delivering where others can’t.
ISO 9001:2015 Certified Across Both Facilities
From first shot to final shipment, our ISO 9001:2015 certification guarantees the process controls and traceability your industry demands.
With robust APQP practices, DFM collaboration, and full PPAP documentation — your critical tolerances and specs stay locked in from run to run.
Versatile Alloy Solutions for
Complex Casting Needs
From high-strength automotive parts to corrosion-resistant outdoor components, our alloy options support your exact design and performance needs.
Known for: Excellent corrosion resistance and castability
Ideal for: Outdoor and marine
applications
Why: High silicon content improves fluidity and makes it highly resistant to environmental conditions — perfect for components exposed to weather or moisture.
Known for: The industry’s most versatile and commonly used die casting alloy
Ideal for: Automotive, electronics, appliances
Why: Offers a strong balance of mechanical strength, thermal resistance, and dimensional stability — great for high-volume parts with tight tolerances.
Known for: A modification of 380 with better castability.
Ideal for: Complex, thin-walled parts in automotive and electronics
Why: Slightly more silicon than 380 makes it easier to cast intricate shapes without sacrificing strength or performance.
Known for: Exceptional wear resistance and hardness
Ideal for: Automotive engine components like cylinder blocks and pistons
Why: High silicon content makes it extremely durable under friction and pressure — perfect for high-performance applications.
Known for: High pressure tightness and corrosion resistance
Ideal for: Hydraulic components, plumbing, and marine parts
Why: Its chemistry makes it ideal for leak-resistant parts and components exposed to water or pressure.
