What Makes Us Different?

As a urethane molding company, we know custom urethane or polyurethane casting is the ideal process to produce near-production quality parts for prototypes and other low-volume needs. Our urethane casting services utilize 3D printing and silicone rubber molds, keeping tooling costs low and turnaround times fast. The unique properties of many production-grade materials can be closely duplicated through different urethane formulations. Especially when compared to plastic injection molding, urethane casting delivers numerous advantages.

Our skilled finishers and model makers complete all finishing, painting, and texturing services in-house. Secondary process treatments, including silkscreen and graphics applications, enable us to provide realistic prototypes tailored to your requirements. The prototype will look, feel, and function as a final product. Elimold’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


Advantages of Urethane Casting 

Before choosing urethane casting for your project, it is important to note the advantages.

Advantages of urethane casting include //

  • Different Colors, Textures & Finishes May Be Used
  • Wide Variety of Materials, Both Rigid & Flexible Options
  • Finer Details Can Be Accomplished

  • Casted Part Can Include Threaded Inserts, Adding Strength To The Part
  • 3D Printed Master Patterns & Silicone Mold Tooling



Common Applications of Urethane Casting

Many industries use urethane casting for their prototype and production projects. Urethane casting can be a smart choice for a lower-quantity project, as investing in injection mold tooling can be expensive. Another advantage of urethane casting is that it is optimal for use as a first production run, serving as a cost-saving measure to test prototypes before larger-scale production. Advanced prototyping is also feasible with urethane casting because the tooling and design changes cost less than other manufacturing methods. It is also possible to test various materials from a single mold. Parts made using urethane casting can also be used for customer testing, given the high aesthetic quality.

Urethane Casting Applications:

  • Test Prototypes Rapid
  • Prototypes Exhibit Parts
  • Consumer Testing
  • Products for Crowdfunding
  • Lower-Volume Manufacturing
  • Concept Models
  • Sales Samples
  • Engineering Models
  • Marketing Test Samples
  • Pre-Production Runs
  • Bridge to Production Parts
  • Point of Purchase Displays
  • Conveyor Systems
  • Medical Devices
  • Specialty Over-Molding
  • Aircraft Interior Components
