Over 50 years of process planning and fixture design experience places Putnam Machine Products among the most capable of contract machine shops in the Midwest.

Manufacturing Process Design and Optimization

  • Machining/Manufacturing Process Planning and Optimization Assistance
  • In-House Workholding and Assembly Fixture Design
  • Foundry Pattern, Stamping Die, and Mold Making Capabilities
  • Processing Container and Packaging Design
  • CNC Programming and CAM Cutting Tool Path Generation Directly From Customer Part and Assembly Models

Putnam has a staff of mechanical engineers and process engineers available for design collaboration. Putnam works closely with many fabricators, foundries, extruders, forging houses, heat treat facilities, and finishers to offer complete components and assemblies ready for customer use.


Putnam manufacturing engineers and CNC programmers are versed in the use of CAD/CAM (computer-aided-design/computer-aided-manufacturing) software for process drawings, fixture design, and CNC program generation. Exchange of electronic design data ensures accurate estimating, fixturing, and machining of components and helps to reduce fixture, pattern, and machine programming time.
