Why Work With CPM

CPM supports aluminum 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.

When CPM Is the Right Fit

  • Prototype to low- and medium-volume production
  • Parts requiring machining, inspection, or documentation
  • Complex geometries or core-intensive designs
  • Programs that benefit from upfront engineering input
  • Projects needing coordinated tooling, casting, and machining
70+ Years in Business  •  ISO 9001:2015 Compliant  •  U.S.-Based Program Support  •  One Accountable Partner from Print to Finished Part
