Urethane casting Service

Rigid Urethane resin casting

Urethane resin casting, also known as polyurethane resin casting, is a manufacturing process used to create prototypes and low-volume production runs. Pour liquid urethane resin into molds to produce rigid and durable products with high precision.

Urethane rubber casting

Urethane rubber casting is a process that uses liquid urethane rubber to create flexible and elastomeric parts with high precision. Similar with rigid urethane resin casting process,but the material is rubber materials.

Benefits of Urethane casting

Reduced Tooling and Part Costs

Silicone molds are cheap and easy to make, and also offer lower part costs especially as the order volume increases. 

fast Production

 Silicone molds can be ready in 24 hours. Up to 50 functional cast urethane parts can be produced in 10 days when you choose urethane casting.  

Design flexibility

urethane casting allows you to create parts with complex geometries and features that would be difficult or impossible to achieve with other methods.

High Precision and Quality

Urethane casting can create high quality parts in a variety of shapes, sizes, and materials — all with good tolerances around ± 0.3 mm.

Excellent Surface Finish

cast urethane parts offer excellent surface finish, and can be post processed like painting, polishing, graining.
