Investment Die Casting
Investment Casting, also known as Lost Wax Casting, is a precision casting process that provides design flexibility and significant cost advantages.
The Investment Casting process involves pouring molten metal into a mold that has been created using a wax model. Once the mold is made, the wax model is melted and drained away.
Hollow cores can be effected by using a heat-proof core that prevents the molten metal from totally filling the mold.
Investment Casting is generally used for small castings, but can be used to produce much larger components.
Dimensional tolerances of ± 0.003 in./in. are readily achieved. Delicate parts with walls as thin as 0.025 in. can be achieved by investment casting.
Investment Casting Reduces Costs
- Investment Casting has lower equipment costs
- Lower cost than machining out of bar stock
- Investment Castng can produce complicated shapes with close tolerances & fine details
- Improved surface finishes, saving time and money on final finishing processes
- Investment casting is material efficient, generating far less waste than wrought processes
- Saves money when using costly alloys
- Investment casting can be used to combine multiple parts into a single unit
- Can produce savings in the number of manufacturing steps
