This directory lists 38 investment casting companies across the United States, from job shops to vertically integrated manufacturers.
Buyers in this space are typically solving problems related to producing components with complex internal passages, thin walls, or exceptional surface finish, where machining would be cost-prohibitive or impossible. They need a process that can consistently achieve tight tolerances and ensure repeatable metallurgical properties, often for mission-critical applications where failure is not an option. This frequently involves components requiring high strength-to-weight ratios or resistance to extreme temperatures and corrosive environments.
The supplier landscape ranges from highly specialized boutique foundries focusing on niche materials like titanium or specific superalloys for aerospace and medical, to larger, more vertically integrated operations that offer comprehensive services from pattern tooling design to secondary machining and non-destructive testing (NDT). Some specialize in air-melt alloys while others boast vacuum melting capabilities for reactive or high-performance materials. Understanding their core focus—whether it's rapid prototyping, high-volume production, or complex assembly integration—is key to a successful partnership.
To effectively engage investment casting companies, buyers should arrive prepared with detailed 3D CAD models, material specifications (including specific alloy grades and relevant ASTM/AMS standards), annual volume forecasts, and clearly defined critical-to-quality (CTQ) features. Suppliers will expect to understand the component's end-use application, any required certifications (e.g., AS9100, NADCAP), and specific NDT requirements like X-ray, FPI, or ultrasonic testing, as these significantly influence process planning and cost.

| Type | Best For | Typical MOQ |
|---|---|---|
| Prototype/Low-Volume Specialist | Initial prototypes, R&D projects, small batch runs, specialized or unique alloy development. | 1-50 units |
| General Industrial Foundry | Medium-volume production (hundreds to low thousands annually) of standard industrial components, balanced cost and quality. | 100-500 units |
| High-Volume/Automated Foundry | Cost-efficient large-scale production (thousands to tens of thousands annually) for mature products with stable designs. | 500-1,000+ units |
| Aerospace/Medical/Superalloy Specialist | Mission-critical components requiring exotic materials, extremely tight tolerances, and stringent certifications (e.g., AS9100, NADCAP). | 50-500 units |
Component complexity directly influences the cost and lead time, primarily due to the wax pattern tooling and subsequent mold creation. Intricate designs with tight tolerances, thin walls, or complex internal features require more sophisticated wax injection dies, meticulous shell building, and often more extensive post-casting inspections, driving up both non-recurring engineering (NRE) costs and per-piece price.
For aerospace components, AS9100 Rev D is almost universally required, alongside NADCAP accreditation for special processes like heat treatment, NDT (non-destructive testing), and potentially welding. Medical devices often demand ISO 13485 in addition to specific material biocompatibility certifications. Always verify that the foundry's melt practice and quality system align with these rigorous standards.
Investment casting excels when your component requires high dimensional accuracy, excellent surface finish, intricate internal features, or complex external geometries that are difficult or impossible to machine. It's also ideal for parts made from hard-to-machine alloys. While tooling costs are higher than sand casting, the reduced post-processing and material waste often make it more economical for medium to high volumes.
The most crucial information includes a detailed 3D CAD model (e.g., STEP, IGES), a 2D engineering drawing with all critical dimensions and tolerances, specified material alloy (e.g., 17-4 PH stainless steel, Inconel 718), annual volume estimates, target price, and any required certifications or non-destructive testing (NDT) such as X-ray or fluorescent penetrant inspection (FPI).
Common NDT methods include Visual Inspection, Fluorescent Penetrant Inspection (FPI) for surface defects, Magnetic Particle Inspection (MPI) for subsurface defects in ferromagnetic materials, Radiographic Testing (X-ray) for internal integrity, and Ultrasonic Testing (UT) for volumetric flaws. These are typically required for critical components in aerospace, medical, defense, or high-pressure applications where internal soundness and defect absence are paramount.
DFM is incredibly important for investment casting. Engaging with your supplier early in the design phase can help optimize part geometry for the casting process, minimize costly design iterations, improve yield, and reduce overall part cost. DFM discussions often focus on factors like minimum wall thickness, corner radii, draft angles, gate locations, and minimizing potential solidification defects.
