Rapid Prototyping / Prototype Development Service
Custom Silicone Mold Prototype
Refine your custom silicone mold prototype through targeted development and iteration cycles. Zagnat supports multiple design revisions to achieve functional, production-ready results.

Custom silicone mold prototypes require precise adjustments across material behavior, cavity geometry, and release features. We focus on iterative testing to validate each version before scaling.
Quote Factors for Silicone Mold Prototypes
- Part complexity and undercuts
- Desired shore hardness and wall thickness
- Number of cavities and gating options
- Iteration count needed for fit and function
Projects start at a $200 minimum. Provide STL, STEP, OBJ, 3MF, or IGES files for review.


Development and Iteration Process
- Review initial files and project goals
- Print or machine first prototype version
- Test mold performance with sample material
- Apply changes based on results and repeat
- Finalize geometry for production handoff
Project Fit
This service suits inventors and product teams needing multiple rounds of silicone mold testing. It is ideal when cavity accuracy, draft angles, or material flow must be validated before committing to tooling.
