Injection Molding Solutions

Choose from prototyping and on-demand manufacturing options

Injection molding can provide a range of lifetime part volumes—from as few as 10 to more than 10 million. Protolabs is a low-volume manufacturer, typically producing 10 to 10,000+ parts from aluminum molds. We provide two injection molding service options. One is best suited for those who need smaller part quantities often associated with prototyping and the other a good fit for those who require larger part quantities common in low-volume manufacturing.

Prototyping or On-demand Manufacturing?

While the molds themselves are similar, part quantities, lifetime maintenance, quality documentation, and pricing vary depending on which service option is chosen. The right one depends on your project needs.

      Prototyping  On-Demand Manufacturing
OBJECTIVE I need to validate my design I need the flexibility of on-demand production of end-use parts
  • Lifetime volumes are likely below 2,000 parts
  • An affordable entry point for tooling is important
  • Part production is only needed for 1 year or less
  • Lifetime volumes exceed 2,000 parts
  • Lower part price is critical
  • Part production is needed for several years

Why Rapid Prototyping?

  • Reduce design risks
  • Test multiple designs simultaneously
  • Accelerate speed to market


Why On-Demand Manufacturing?

  • Manage demand volatility
  • Reduce total cost of ownership
  • Leverage cost-efficient bridge tooling

Enhanced Quality with Digital Inspections

Digital inspection reports on molded parts are available on every on-demand manufacturing order. Our metrology lab uses a 360-degree, 12-position 3D scanner that collects data, identifies dimensional variance, and creates a visual aid and color map for a direct CAD-to-scan comparison.
