Prototyping with Injection Molding

Reduce mold costs and validate part designs with a low-cost prototype tool

We have two injection molding service options—prototyping and on-demand manufacturing—and each offers its own benefits depending on your project needs. If part quantities are lower, an affordable entry point for tooling is important, and rapid development over a short period of time is critical, our prototyping option works great.


Prototyping Tool for Molding

MOLD PRICE Lower than on-demand manufacturing tool
PART PRICE Higher than on-demand manufacturing tool
MOLD CAVITIES Single and multi-cavity
GUARANTEED MOLD LIFE Limited (guaranteed for at least 2,000 shots)
MOLD STORAGE Stored for 18 months of inactivity
QUALITY DOCUMENTATION Basic and digital inspection reports available upon request
  • Aluminum molds
  • Standard lead time of 15 days or less
  • Tolerances of +/-0.003 in. plus resin tolerance (in./in.)
  • Set-up fees apply to each run

Why Use a Prototyping Tool?

Design Feedback

  • Receive interactive design for manufacturability feedback with every quote to make early adjustments before prototyping begins.
  • Talk with applications engineers to discuss any design challenges and manufacturing questions that arise.

Iterative Development

  • Have physical prototypes in hand within days to quickly modify designs during early product development.
  • Produce multiple prototypes at the same time to compare and iterate designs simultaneously.
  • Reduce overall time to market with an iterative product development cycle.

Design Validation

  • Test the form and fit of components with small quantities of molded parts.
  • Perform functional test with prototypes manufactured in production-grade materials.
  • Full library of online design resources including guidelines, tips, white papers, and videos.

Market Testing

  • Produce a pilot run injection-molded parts to validate market interest before launch.
  • Reduce financial risk at market launch by implementing affordable aluminum tooling before full-scale production begins.
