Urethane Casting
When multple parts are needed, RTV (room temperature vulcanized) tooling and Urethane casting can be used to fill the gap between prototype and production. Urethane prototypes can be of nearly any size and shape and can be color matched by either a pantone number or a color chip. Whether you require inserts, over molding, copper shielding, molded in color/texture or painted in custom color/texture with applied graphics, our Urethane casting department will meet your required specifications. |
|
Overview: |
|
The RTV mold (also known as silicone rubber) is created using a master pattern. The master pattern can be created by CNC machining or SLA. The platinum based silicone rubber is poured around the master pattern to create a cavity and a core. The master is then removed, leaving a void in which a wide variety of materials may be cast. |

Urethane Casting Applications: |
|
- Visual models
- Low volume production
- Product testing
- Color and texture studies
- And more

Urethane Casting Materials: |
|
At Schmit Prototypes, a prototype material can be chosen to match nearly any production material, from 5 shore A to 80 shore D. Some of the many materials that can be used are: two part thermoset urethanes, silicone rubber, wax and epoxies. Prototype materials and processes can simulate many of the thermoplastics' characteristics of hardness, clarity, flexibility and impact resistance, giving you cast urethane prototype the same look and feel as a true production part. |
|
Urethane Casting Finishing: |
|
Little to no finishing is required on cast urethane parts because the desired textures and finish levels are applied to the master pattern. |
|
Cast Urethane Part Delivery: |
|
At Schmit Prototypes the average delivery time for cast urethane parts can vary depending on part geometry and material selected. Please contact one of our project managers for more information on cast urethane delivery timeframe. |

Why Urethane Casting? |
|
- Because of the flexibility of the silicone, reverse draft, inserts and undercuts are more easily dealt with than in injection molding.
- Silicone molds are capable of reproducing incredible detail, including custom textures.
- Urethane casting provides fast turnaround.
