SILICONE MOULDING
URETHANE MOLDING FOR SMALL BATCH PRODUCTION
Urethane Casting/Silicon Molding
Urethane casting provides end-use, rigid or flexible plastic parts with production-level quality. Built without expensive and time-consuming hard tooling, our urethane casting process uses a 3D printed master pattern and silicone molds to deliver high-quality, short-run parts up to 30” long. The finished dimensions of urethane cast parts depends on the accuracy of the master model, part geometry and casting material. In general, a shrinkage rate of + 0.15% is expected.
Advantages of Urethane Casting
Durability
Polyurethane cast materials are available in rigid or flexible end-use plastics. Urethane cast parts are generally as tough or tougher than injection molded pieces, and are significantly stronger than 3D printed counterparts.
Scalability
Our casting process is optimal for low-volume production for quantities of one to several hundred. On average, a silicone mold can accurately cast about 20-25 parts. The maximum quantity varies based on part design and material cast.
Material Selection
We offer a wide range of rigid and flexible urethane cast materials, from very soft and flexible (Shore A) to extremely rigid and impact resistant (Shore D). Parts are cast in a color that is blended to your specifications.
Color Matching & Finishes
The urethane casting process is capable of reproducing small details. Little to no finishing is required, because the desired textures and finish levels are applied to the master pattern.
Rapid Turnaround
Urethane cast parts are shipped within 15 business days, depending on order specifications and volume. By contrast, injection molded parts can take months to build.
