Manufacturing Process Index

How products get made.

Manufacturing processes transform raw materials into functional parts, assemblies, and finished products. Explore subtractive, formative, casting, fabrication, cutting, joining, and additive production methods used throughout modern industry.

V-01 Material Compatibility Match the process to material behavior.
V-02 Production Volume Balance tooling against quantity.
V-03 Dimensional Requirements Consider tolerance and surface finish.
V-04 Part Complexity Evaluate geometry and feature access.
03 / Process Selection

What determines the right process?

Process selection is usually a compromise between technical requirements and production economics. The same component may be manufacturable using several methods, but not every method will be appropriate at the required quantity or tolerance.

01 Material Material strength, melting temperature, machinability, ductility, thermal behavior, and chemical resistance can eliminate or favor specific production methods.
02 Quantity Processes with expensive tooling may become economical at higher production volumes, while machining and additive manufacturing can be practical for smaller runs.
03 Geometry Internal cavities, deep features, thin walls, undercuts, long profiles, and complex surfaces may favor one manufacturing method over another.
04 Tolerance Dimensional accuracy and repeatability vary significantly between machining, molding, casting, forming, fabrication, and additive methods.
05 Surface Finish Some methods create finished surfaces directly, while others commonly require machining, polishing, grinding, coating, or other secondary work.
06 Tooling Cost Mold, die, fixture, programming, and setup requirements influence the economics of both initial production and future design changes.
04 / General Comparison

Production characteristics by process.

These general relationships provide a starting point for research. Actual capabilities depend on material, equipment, supplier expertise, component geometry, tolerances, tooling, and production requirements.

Process Typical Materials Prototype Use Volume Production Tooling Requirement
CNC Machining Metals / Plastics Strong Low–Medium Low
Injection Molding Thermoplastics Limited High High
Die Casting Nonferrous Metals Limited High High
Metal Stamping Sheet Metals Moderate High Medium–High
Laser Cutting Metals / Polymers Strong Medium Low
3D Printing Polymer / Metal / Resin Strong Low–Medium Very Low
Process Principle

The best manufacturing process is not simply the one capable of making the part. It is the process that satisfies geometry, material, quality, quantity, and cost together.
