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.
From print review through final inspection, each project is handled by one accountable team.
End-to-End Casting Support
Cast iron casting support from tooling through final inspection, with in-house pattern equipment, machining, and project support.
| Cast Iron Grades | Gray Iron Class 25, Class 30, Class 35, and Class 40. Grade selection based on strength, machinability, and application requirements. |
|---|---|
| Pattern Tooling | In-house pattern design and build for prototype and production tooling. Urethane, wood, and aluminum based on part geometry, quantity, and lead time. |
| Casting Processes | Green sand, no-bake, and 3D printed molds for low- to medium-volume cast iron castings. 3D printed molds support rapid prototyping, complex geometry, and reduced lead times without hard tooling. |
| Core & Part Complexity | Complex core geometry, internal passages, and multi-core assemblies. |
| Heat Treatment | Heat treat based on alloy, mechanical requirements, and end-use application. |
| Machining | CNC machining to finished part specifications. Critical features and close-tolerance areas. |
| Finishing & Surface Treatments | Anodizing, painting, powder coating, and other surface treatments based on part requirements and end-use environment. |
| Inspection, Testing & Documentation | Dimensional inspection and NDT coordination. X-ray and liquid penetrant inspection as required. FAIR, PPAP, and material certifications. |
| Engineering & Program Support | Print review and manufacturability input. Alternate methods such as billet hog-outs for early-stage or low-quantity requirements. |


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 built and controlled in-house, allowing faster iterations and better alignment between tooling and production.
One Accountable Team
From initial print review through final delivery, each project is handled by a single team responsible for execution, quality, and timing.
Process-Driven Results
Clear workflows from tooling through machining and inspection reduce variability and keep projects moving predictably.
Flexible Volumes
Built for prototype through low- to medium-volume production without the constraints of high-volume foundries.
Consistent Delivery
Repeatable processes and defined checkpoints help ensure parts are delivered as expected and to specification.
When CPM Is the Right Fit
This page is built for buyers and engineers sourcing cast iron castings that need more than a basic quote.
CPM is a strong fit when:
- You need cast iron castings with machining completed
- You want one accountable source for tooling, casting, and finishing
- You are working from a print and need help developing the casting
- You need consistent repeat production, not just a one-off sample
Typical cast iron castings include:
Housings, machine bases, pump housings, valve bodies, covers, and brake components.
