Low to Medium Volume Ductile Iron Castings
Every print is personally reviewed before we quote. You’ll hear back within 24 hours.
In-house pattern tooling and print review. One accountable partner from print to finished part.
Casting Capabilities
Grades, size range, tooling, processes, and inspection for ductile iron (also called nodular or SG iron) sand castings.
| Ductile Iron Grades | ASTM A536 grades 60-40-18, 65-45-12, 80-55-06, and 100-70-03 Grade selection based on strength, ductility, machinability, and application requirements |
|---|---|
| Part Size & Production Range | 0.1 lb to 3,000 lb typical casting weight No minimum order quantity. Prototype through repeat production supported based on part requirements. |
| Pattern Tooling | In-house pattern design and build Wood, urethane, and aluminum tooling options selected around geometry, volume, and production life |
| Casting Processes | Green sand and no-bake (airset) molding 3D printed molds available for rapid prototyping, design validation, and complex geometry Process selected based on part requirements, volume, and lead time |
| Heat Treatment | Heat treatment specified based on grade, mechanical requirements, and customer specifications |
| Machining | Machining support through finished part requirements Critical features, datum structure, and inspection approach reviewed before production |
| Finishing & Surface Treatments | Painting, coating, plating, and other treatments coordinated when required Finishing selected based on application, environment, and customer specifications |
| Inspection, Testing & Documentation | Dimensional inspection with reporting, including first article layouts when required Magnetic particle, liquid penetrant, or other testing available as required FAIR, PPAP, material certifications, and ISO 9001 quality documentation supported MIL-spec material, testing, and documentation requirements supported |
| Engineering & Program Support | Print review and manufacturability feedback before quoting and production Gating, riser, tooling, machining, and alternate manufacturing approaches reviewed when appropriate Each job is matched to the foundry partner best suited to its grade, part size, and quantity |
Ductile Iron Castings
What We Watch For in Ductile Iron
Every ductile iron print is checked for the problems that usually show up later, at the foundry, in machining, or in the field. These are the ones we look for first.
Shrinkage at Heavy Sections
Hot spots and section changes need proper feeding. We review section transitions and feeding before tooling is built.
Carbides in Thin Sections
Thin walls cool fast and can form hard carbides that are tough to machine. We check wall thickness against the grade and the machining plan.
Grade vs. Section Size
Higher-strength grades like 80-55-06 and 100-70-03 behave differently in heavy sections. We confirm the grade can be met at your part’s thickness.
Mechanical Property Callouts
Properties from separately cast keel blocks and properties cut from the casting are very different requirements. We check which one the print calls for.
Nodularity and Testing Callouts
Nodularity, microstructure, and MT or UT requirements add cost and lead time. We flag them at quote so nothing is missed.
