Urethane Casting
RTV Molding
URETHANE PROTOTYPES
Wide Range of material properties available: Shore A, Shore D, Flame Resistant, UL Rated, Optically Clear as well as food grade.
Cast urethane prototypes (RTV molding) are often used when color, surface quality, and toughness are required. Urethane casting creates plastic prototypes with material properties similar to engineered production plastics. These prototypes are cast from two part liquid polyurethanes into silicone rubber molds.
EXAMPLE APPLICATIONS:
Functional Prototypes
Visual Models
Product Testing
Color Testing
Engineering Design Verification
Small Batch Manufacturing
Market Testing
Pre-Production Parts
PRODUCTION LEVEL PARTS
Urethane casting provides end-use parts with production level quality & material properties.
Urethane parts (RTV molding) are made without expensive and time-consuming hard tooling. The urethane casting processes uses a 3D printed master pattern and silicone molds to delivery high quality, short-run parts.
RTV molding is an inexpensive way to bridge the gap between prototype and production.
Ordering Guide For Our Casting Process
Design
You can design for the casting process, however, it is more advantageous to design for the manufacturing process you will ultimately be using. Then make any small changes needed for the casting process, if any.
So if you are making a plastic container which will be manufactured utilizing injection molding, please use injection molding design considerations.
If you are unsure of the ultimate manufacturing process to be used, it is safe to use injection molding standards but keep in mind the tolerances shown in our Casting Design Considerations.
