The Wabtec Difference

3D Printing/Rapid PrototypingPerma-Cast offers 3D Printing/Rapid Prototyping!

Perma-Cast does it right the first time using our 3D printing capabilities. We create a prototype to ensure accuracy before going into production.

Turn your design into a real tangible part using our 3D printing/rapid prototyping. Can be used to verify and test designs before production begins, or simply use as a display.

Perma-Cast can work within your schedule and budget.

Permanent mold castings, produced through our unique chill cast, gravity fee process, offer many benefits over the othe casting methods.

• Casting Integrity• Dimensional Repeatability• Homogeneous Grain Structure• 25 RMS Surface Finishes

Alloy selection includes electrolytic copper (IACS of 95% or higher), brass, and aluminum bronze. The Alloy Selection guide in this brochure is designed to assist you in determining the proper alloy for your application.
