LOW COST AND FLEXIBILITY WITH ARRK’S CAST URETHANE PARTS IN ASIA FOR YOUR MANUFACTURING REQUIREMENTS
Our urethane casting service enables you to obtain high quality, low volume production-like parts in various plastic and soft urethane materials. Casted parts can be produced in a wide range of colors and textures which ARRK will pigment match according to selected Pantone, NCS, RAL colour codes or even based on physical colour samples. Our cast urethane parts will closely resemble your final end product not only in shape and size but also in both appearance and finish. Urethane castings provide a visual, practical, and functional working model that is extremely valuable for early market research.

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
Firstly, a master model is either 3D printed or CNC machined based on the 3D CAD model of the part to be casted. The latter being a better choice due to the improved strength and accuracy of the master produced.
Next, liquid silicone rubber is poured around the master model covering the entire part and creating a rectangular rubber mould when the silicone rubber sets and hardens. The rubber mould is then split into cavity and core halves and the master is then removed, leaving a void where several materials can be introduced for casting.
Due to the soft and flexible nature of the silicone moulds, part designs generally do not require draft angles and cast parts can be easily removed reliably multiple times. Undercuts and fine details can be addressed by using mould inserts where necessary. While a silicone mould wears out faster then its steel counterpart, it is vastly more cost effective for lower volume prototype parts with compatible production quality and finish.
As our highly trained and experienced team at ARRK is always running tests and validating processes, we are able to resolve any possible production issues way in advance.
ARRK implements stringent quality checks throughout our manufacturing processes to ensure that the urethane casting parts are always of the highest quality attainable. We are always there to guide you on the best possible ways to realise your product design.

FINISHING PROCESSES WITH MASTER CRAFTSMANSHIP AND EXPERIENCE
Our teams of experience and master model makers would meticulously handle all the finishing, painting and texturing work and services in-house. Secondary process treatments, including silkscreen and graphics transfer application enable us to produce realistic consumer prototypes that are tailored towards your design vision. The prototype will have the aesthetic and functions of the final product. ARRK’s rigorous quality standards are upheld with delivery schedules on track.
We provide a wide range of additional finishings and secondary processes:
- Spray Painting Texture / Gloss
- Logo and Graphics Application
- Electroforming Plate
- Gold Color
- Spin Line
- Sputtering
- Vacuum Metalize
BENEFITS OF URETHANE CASTING WITH ARRK

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.
