Urethane Casting
We are able to reproduce your design with urethane castings by using a stereolithography master or a machined master to create RTV silicone rubber molds. Our urethane casting service ensures consistent excellence whether you need a small quantity or several hundred castings.

URETHANE CASTING CAN PROVE EXTREMELY VALUABLE FOR EARLY MARKET TESTING
Our urethane casting service gives you access to high quality, low volume “production-like parts” in a variety of rigid, and soft urethane materials. Castings can even be colored to a wide range of colors and textures and ARRK will match pigments for Pantone, RAL, or samples provided. Our cast urethane parts resemble your final product not only in shape but also in appearance and finish. Urethane castings provide a visual, practical, and functional evaluation plus can prove extremely valuable for early market testing.

Urethane casting process
STAGE 1. Master model
STAGE 2. Silicone mold
STAGE 3. Casting chambers
STAGE 4. Urethane part
A Master Model is created with all part features and finishing details to be reflected in the mold.
A fast curing silicone rubber mold is produced using the Master Model as a pattern.
ARRK injects our two-part urethanes into the mold inside vacuum pressure chambers.
Cured parts removed from the mold precisely and consistently duplicate the master model.

CREATING CUSTOM MANUFACTURED URETHANE CASTINGS
A master model is often 3D printed using Stereolithography for its ability to be finely finished. Additionally, CNC master models are also a good choice, primarily because of their strength and ability to produce more significant quantities with tighter overall tolerances. Next, silicone rubber is poured around the master pattern, creating a cavity and a core. The master is then removed once the silicone rubber sets and leaves a void into which several materials may be cast.
Urethane casting designs do not require draft on small parts. Due to the flexibility of silicone molds, cast parts can be removed easily. Undercuts and fine details are replicated using mold inserts where necessary. While a silicone mold wears out quickly, it is vastly more cost effective for very low volume and prototype plastic parts with production-level quality and surface finishes.
Highly trained technicians and experienced molders at ARRK North America, Inc. use their inventiveness to resolve any possible production issues in advance. We perpetually run tests and validate processes.
ARRK implements quality checks throughout manufacturing to ensure you receive the highest quality urethane castings available. We guide you through the best ways possible to produce your product design.

Finishing processes with master craftsmanship and experience
Our team of skilled finishers and model makers carry out all finishing, painting and texturing services in-house. Secondary process treatments, including silkscreen and graphics application, enable us to provide realistic prototypes tailored to your exact requirements. The prototype will look, feel, and function as a final product. ARRK’s rigorous quality standards are upheld, and delivery schedules are maintained.
We have a wide range of additional finishing options we provide, depending on what is needed for the project:
- Spray Painting Texture / Gloss
- Logo and Graphics Application
- Electroforming Plate
- Gold Color
- Spin Line
- Sputtering
- Vacuum Metalize

TESTIMONIALS
ARRK is my go to prototyping supplier when I want a high quality prototype delivered on time. I know I will get a prototype that has the look of a release ready product and I will get it on the promised delivery date. I frequently get compliments on ARRK built parts for their fit and finish. The conversation typically starts with “Is this a prototype or actual part?” The conversation ends with “ Where did you get that done?” In fact, the parts are of such high quality that I have to frequently remind people that they are prototypes so be careful with them!
EngineerMedical Device Manufacturing Company 
In the nearly 30 years of developing products there is only one company we go to now to “partner” with on our product development; ARRK Product Development Group. We know we can count on their quality, experience, ability, skill and turnaround time which is essential to our success. ARRK is more of a partner in this process than a company that just delivers parts. They advise and consult with us as we go along the development process. We can count on them to deliver what they promise without any excuses. ARRK plays an instrumental part in our success.
Sr. Engineering ManagerDesign and Engineering Company
ARRK consistently meets constrained schedules to deliver top quality models each time. Their customer service is second to none in the passion and commitment to ensure the customer’s requirements are met. Their overall level of excellence remains the reason that they are our primary source for rapid prototyping.
