Cast Silicone//Silicone is durable, stretchy, tear-resistant, inert, easy to clean, and has a high-temperature resistance. Silicone casting is ideal for medical devices, surgical models, props, soft-touch housings, and more.
Urethane casting services typically involve the following steps:
Master Pattern Creation: A master pattern of the desired part is created using methods such as 3D printing, CNC machining, or manual modeling.
Mold Making: A silicone mold is created from the master pattern to replicate the part's shape and details.The finished dimensions of urethane cast parts depend on the accuracy of the master model, part geometry, and casting material. In general, a shrinkage rate of + 0.15% is typical.
Material Mixing and Casting: Polyurethane material is mixed and poured into the mold. The material cures and hardens to form the final part.
Part Finishing: After the casting process, the parts may undergo finishing processes such as trimming, sanding, painting, or additional surface treatments.
Urethane casting services are often chosen for their cost-effectiveness, quick turnaround times, and ability to produce high-quality parts with complex geometries.If you are looking for a company that provides urethane casting services,From design to prototype and production, our team of engineers is ready to help bring your idea to life.

how to cast urethane rubber?
Mix Urethane Rubber: Select a two-part urethane rubber material that meets your project requirements in terms of hardness, flexibility, color, and other properties. Follow the manufacturer's instructions to mix the two components in the correct ratio.
Degassing (Optional): To remove air bubbles from the urethane rubber mixture, you can use a vacuum chamber to degas the material. This step helps ensure a smooth, bubble-free casting.
Pouring: Carefully pour the mixed urethane rubber material into the mold. Be sure to pour slowly and evenly to prevent trapping air bubbles in the mixture.
Curing: Allow the urethane rubber to cure and harden according to the manufacturer's instructions. The curing time may vary depending on the specific type of urethane rubber used and environmental conditions such as temperature and humidity.
Demolding: Once the urethane rubber has fully cured, carefully remove the part from the mold. Depending on the complexity of the mold and part design, you may need to use release agents or techniques to facilitate demolding.
Post-processing (Optional): After demolding, you can trim any excess material, clean up the part, and perform any additional post-processing steps such as painting, finishing, or assembly as needed.
Testing and Quality Control: Inspect the cast urethane rubber part for defects, surface imperfections, dimensions, and overall quality. Perform any necessary testing to ensure that the part meets the required specifications and performance criteria.
By following these steps and taking proper precautions, you can successfully cast urethane rubber parts for various applications such as prototypes, industrial components, custom molds, seals, gaskets, and more.
