About the process
From product development models and prototypes to low-volume production runs, this rapid prototyping process allows us to produce parts that accurately mimic the color, texture, feel and physical properties of injection molded parts.
- Accurately mimic production colors and textures
- Large material selection – rigid, flexible, durable, clear and high-temp
- Offers similar physical properties to injection molded parts
- Used for pre-production runs
- Parts made for marketing samples and test prototypes
- Low-volume manufacturing
Cast Urethane parts can be complete and delivered in days after completing SRM tooling (Silicone Rubber Molds). Short runs of several hundred pieces can be delivered within weeks in most instances.
One of the greatest benefits of the Cast Urethane process is the ability to over-mold existing parts or hardware with a second material.

Functional: Basic level of finish where functionality is more important than cosmetic appearance. Parts will be furnished flat black with a light texture. Small imperfections such as air voids, slight discoloration, parting line, gate, and vent marks, and small scratches resulting from part finishing may be visible.
Show: Premium level finish where cosmetic appearance is important. Parts can be furnished in any of our available color, sheen, and texture options. Unless otherwise specified, the part color will be flat black with a light texture. Visible cosmetic surface will be sanded smooth and painted to eliminate any visual defects. For elastomeric parts or parts which cannot be painted, small imperfections such as air voids, slight discoloration, parting line, gate, and vent marks, and small scratches resulting from part finishing may be visible. Internal surfaces will be painted to eliminate most visual defects.
Clear (Polished): Premium level finish using clear or tinted transparent materials. All surfaces will be polished smooth for clarity. Small imperfections such as air voids, slight discoloration, parting line, gate, and vent marks, and small scratches resulting from part finishing may be visible. Clear coat may be applied for clarity.
