Precision Zinc Die Casting
Built to Last Generations
Family-owned for over a century. ISO 9001 & 13485 certified. NADCA award-winning parts that meet the tightest tolerances in the industry.
Over a Century of Precision
Since 1908, DeCardy Diecasting has provided the highest quality zinc die cast parts to customers throughout the United States and around the world.
Our business started at the turn of the century casting components for American Flyer and other manufacturers. Still family owned and operated, our parts today are found in motorcycles, cars, trucks, precision medical equipment, and electronic testing devices.
The DeCardy Difference: Customers choose us for our engineering expertise and concurrent engineering process that resolves aggressive design challenges. Our central US location eliminates the logistical, communication, and quality issues of offshore sourcing.
The CELL Method: Every DeCardy project is assigned to a dedicated CELL that includes all personnel needed to complete it. Unlike traditional assembly-line systems, this approach optimizes quality and scheduling control, delivering cost savings of 18% to 54%.
Why Choose Zinc Die Casting?
Zinc delivers unmatched economics and performance — from miniature electronics to heavy automotive components.
Particularly economical for small parts, zinc's low melting point promotes exceptionally long die life — often exceeding 1 million parts from a single tool.
Compared to plastic injection molding, zinc castings are much stronger with closer tolerances and thinner walls. Versus stamping and forging, zinc casting produces more complicated shapes with better accuracy and less labor.
And compared to machining, zinc die casting produces complex shapes that would otherwise require many different set-ups and sophisticated tools.
Physical Advantages
High ductility, dimensional stability, high impact & tensile strength, thin wall sections, close tolerances, temperature resistant.
Manufacturing Benefits
Long tool life (1M+ parts), multiple features in one process, low melting point, good electronic signal shielding.
Finishing Options
Chrome & nickel plating, e-coating, powder coating, chromating, and multiple precision surface finishes.
Our Services
Full-service zinc die casting from concept to production-ready parts — all under one roof.
High Pressure Zinc Die Casting
Advanced zinc die casting with tolerances of ±0.0005" for difficult and complex parts. Capabilities include parts up to 24" in size, shot weights up to 2 lbs, and 250–700 shots per hour. Long tool life (1M+ parts per die). Utilizing Techmire, Frech, and Roto-Finish equipment for miniature to large components across electronics, medical, automotive, and industrial applications.
Secondary Services
Comprehensive in-house finishing, assembly, and packaging. Deburring, semi-polishing via Vibramilling, chrome & nickel plating (electro and electroless), e-coating, powder coating, chromating, and precision grinding. From partial to full assembly with customized packaging — completing and shipping production-ready parts from one location.
Design Assistance & Concurrent Engineering
DeCardy's concurrent engineering process optimizes quality and productivity from concept to production. Services include design optimization, flow and thermal casting analysis, prototyping, tool maintenance, and SolidWorks file support. Typical lead times of 4–6 weeks.
Quality Assurance
ISO 9001:2015 and ISO 13485:2016 certified facility with comprehensive quality assurance regimens. Every part undergoes optical comparator testing. Member of NADCA (North American Die Casting Association) and TMA (Tooling and Manufacturing Association). Multiple NADCA International Competition award winner.
