Custom Urethane Parts

Urethane Castings

Stronger, wear-resistant, tougher, versatile. These features of cast urethane parts are important advantages over parts made of conventional elastomers and plastics in a variety of industry applications. This is why the urethane casting process has been used in rapid prototyping for years.

In parts production, a wide range of design and technical challenges can be overcome with polyurethane elastomer products. This is due to urethane's unique combination of engineering properties allowing urethane to be substituted for many other rubbers and plastics with better results.

Advanced Prototyping manufactures custom urethane parts from silicone molds, using a master prototype to develop the mold. This master prototype can be a part that you supply or a SLA prototype (stereolithography) which has been created from a 3D CAD drawing. The urethane liquid is mixed and injected into the silicone mold using the RIM (reaction injection molding) process inside a vacuum chamber.

With the flexibility of the silicone, reverse draft, inserts, and undercuts are more easily dealt with than in the injection molding process. Silicone molds are capable of reproducing tremendous detail. Urethane casting provides fast turnaround. After curing, the mold is used to create cast urethane prototypes of your design. Urethane part delivery is approximately 2 weeks.
