Low to Medium Volume Cast Iron Castings
We deliver low- to medium-volume cast iron castings with in-house pattern tooling, machining, and engineering support.
One accountable partner from print to finished part.
Casting Capabilities
Cast iron casting support from tooling through final inspection, with in-house pattern tooling, machining, and engineering support. One accountable partner from print to finished part.
| Cast Iron Grades | Gray Iron Class 25, Class 30, Class 35, and Class 40 Grade selected based on strength, machinability, damping characteristics, and application requirements |
|---|---|
| Part Size & Production Range | 0.1 lb to 3,000 lb typical casting weight Prototype through ~5,000 pieces annually Scalable based on part requirements |
| Pattern Tooling | In-house pattern design and build Wood, urethane, and aluminum tooling Built for prototype through production requirements |
| Casting Processes | Green sand and no-bake (airset) molding 3D printed molds for rapid prototyping and complex geometry Process selected based on geometry, volume, and lead time |
| Core & Part Complexity | Complex core geometry and internal passages Multi-core assemblies |
| Heat Treatment | Specified based on grade and performance requirements |
| Machining | Machined to finished part specifications Critical features held to print tolerances Close-tolerance features completed to print |
| Finishing & Surface Treatments | Painting, coating, oiling, and other treatments Based on application and environment |
| Inspection, Testing & Documentation | Dimensional inspection with reporting (including first article layouts) Magnetic particle, liquid penetrant, or other testing available as required FAIR, PPAP, and material certifications available Produced in accordance with ISO 9001 quality standards |
| Engineering & Program Support | Print review and manufacturability feedback Gating and riser design support Alternate methods and tooling strategies evaluated when appropriate |
Cast Iron Casting Examples
Why Work With CPM
CPM supports cast iron casting programs with in-house pattern expertise, controlled execution, and one accountable team from print review through final delivery.
In-House Pattern Expertise
Pattern tooling is designed and built in-house, allowing faster turnaround, better process control, and more efficient casting development.
One Accountable Partner
One team is responsible from print review through final delivery, keeping communication, timing, and execution aligned throughout the program.
Process-Driven Execution
Defined workflows from tooling through machining and inspection reduce variability and support consistent, repeatable results.
Flexible Volumes
Built for prototype through low- to medium-volume production without the constraints of high-volume foundry models.
Consistent Delivery
Clear checkpoints and controlled execution help ensure parts are delivered as expected and to specification.
