  • Did you know ?

    • Urethane castings can be painted and finished.

    • We strive to be your turnkey provider of all your prototyping and low volume production needs.

    • Connex500 Polyjet parts can be painted.

    • Horizontally oriented Stereolithography (SLA) parts build faster and cheaper, but magnify the stair steps used in the model.

    • Stereolithography (SLA) parts can be used as mold masters.

    • Silicone has a limited life cycle depending on the casting material chosen.

    • The Stereolithography (SLA) process can also build QuickCast masters.

    • Part geometry determines silicone mold life.

    • Pucks can be insert into molds during the molding process to simulate tactile feel in silicone keypads.

    • We can machine all types of materials.

    • Material choices greatly affect the cost of your machining project.

    • Urethane parts can be cast in specific colors and with specific textures to meet your design needs.

    • Stereolithography (SLA) parts designed with the long axis of the model oriented vertically take longer to build, but reduce the number of stair steps used.

    • We can be your low volume production supplier for parts in metals, plastics, and more.

    • As you cast your models, urethane permeates the silicone mold over time and degrades the accuracy of your mold.

    • Stereolithography (SLA) parts are used in investment casting.

    • Wall thickness makes a difference in the stability of urethane castings.

    • Silicone molds are a great solution for low volume production.

    • We can build your aluminum tooling for plastic injection production.

    • Electrodag shielding can be applied to urethanes as needed for production models and functional prototypes.

    • We can provide you with referrals for industrial design advice and mechanical engineering.

    • Urethanes come in a wide range of different durometers and Shore A & D varieties.

    • Radii can greatly affect the cost of your machining project.

    • Parts can be cast in silicones as well as urethanes.

    • Machining tolerances can greatly affect the cost of your project.

    • Silicone parts can be painted and finished.

    • Silicones come in a wide range of different durometers and Shore A & D varieties.

    • The use of Connex500 Polyjet parts for masters can lead to cost savings in some applications.

    • If your Stereolithography (SLA) part’s walls are thick enough they can be hollowed out to save on production material costs.
