Casting Capabilities
Classes, size range, tooling, processes, and inspection for gray iron sand castings.
| Cast Iron Grades | ASTM A48 gray iron Class 25, Class 30, Class 35, and Class 40 Class selection based on strength, machinability, damping characteristics, 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 class, 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, oiling, 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 class, part size, and quantity |
Cast Iron Castings
What We Watch For in Cast Iron
Every cast 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
Heavy junctions and hot spots can draw porosity if they are not fed. We review section transitions, gating, and risers before tooling is built.
Chill in Thin Sections
Thin walls and sharp corners cool fast and can form hard, chilled edges that are tough to machine. We check wall thickness against the class and the machining plan.
Class vs. Section Size
Strength in a gray iron casting drops as sections get heavier. We confirm the class can be met at your part’s thickness.
Pressure-Tight Parts
Porosity can cause leaks in pump, valve, and hydraulic housings. If the print calls for pressure testing, we plan for it at quote.
Hardness and Test Callouts
Hardness ranges and tensile bars cast separately from the part are different requirements. We check which one the print calls for, and flag any testing at quote.
