Metal prototype parts for nearly any application

When you need metal prototype parts, you have options that may change from project to project. Often the same project can be completed using different techniques depending on your cost, materials, lead-time and quality requirements. Each application has pros and cons depending on material, tolerance, cost and lead-time. Use our metal prototype chart for a quick reference tool in deciding if investment casting suits your needs. If you decide that you need a plastic prototype model please select the process in the column to the left that best suits your needs.

Investment Casting
Investment casting applications can begin with an SLS CastForm or a wax pattern. The pattern is dipped it in a ceramic slurry. The slurry dipping process is repeated until a strong shell coating surrounds the pattern for support. Once this process is completed, the shell with the pattern still intact is heated in a furnace. At the proper temperature, the SLS CastForm pattern is flashed out or the wax pattern is melted out to leave a cavity in a ceramic mold. The mold is then ready to be used for casting metal.
