Metal Parts from Investment Casting: 3D-CAM modernizes an Ancient Technique.

3D-CAM has a cost-effective solution for any type of metal prototype you need

3D-CAM has a variety of ways to make the wax patterns for this process including:

  • CNC-Machined wax tooling
  • Epoxy-Aluminum tooling
  • SLA Quickcast method to provide the plastic patterns for the investment casting
  • SLS castform material to provide wax patterns for investment casting
  • Investment Castings are ideal for:
  • Quick, cost-effective metal prototypes and production parts

Material choices include:

  • Aluminum
  • Stainless steel
  • Bronze
  • Other ferrous and non-ferrous metals

Dimensional tolerances:

  • +/- 0.020” to +/- .040”
  • Post machining is necessary for
    better tolerances

Turn-around:

  • 1 to 3 Weeks after Quickcast or wax pattern availability

Finishing types:

  • Bead blast or textured surfaces available 125 RPM
  • Post machined accurate surfaces where necessary
  • Polish
Investment casting (also called Lost Wax Casting), is one of the oldest metal-forming techniques. The castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. The process uses a wax pattern invested in a ceramic shell made with multiple dips in a ceramic slurry. When the shell dries, it is baked causing the wax to melt away. Then metal is poured into the empty shell. When the metal is solidified and cooled, the shell is broken away.
