Urethane Casting

Urethane Casting


Urethane Casting with FATHOM is an efficient way to get low quantities of parts in production-like materials on a short timeline. Using 3D printing, CNC machining and in-house finishing services to create quick-turn master patterns for silicone rubber mold making, the FATHOM team can quickly create multiple models that closely mimic materials, color, finish, and design-for-manufacture of production parts, without investment in metal tooling.

Custom prototypes, functional models in production quality materials, and short-run or low-volume production of less than 100 parts—these applications are best-suited to FATHOM’s unique combination of additive and subtractive methods (3D printed and CNC machined master patterns). For quality, production-material parts within one to two weeks, Urethane Casting by FATHOM is the best choice.

Common Applications Include:

  • Low-Volume Production Parts
  • Prototypes & Pre-Production Parts
  • Production Material Parts for Functional Testing
  • Overmolds & Functional Rubber
  • Intricate Parts with Specific Material Properties

Urethane Casting enables companies to get production material parts in their hands quickly, whether you’re in the midst of the prototyping phase of product development or needing production-like parts for final tests and presentations.

Typically, silicone molds yield about 15-25 parts during the Urethane Casting process, as the mold can begin to deteriorate after heavy use. Speak with a FATHOM expert to learn more about this service and if it is the best option for your project.
