Is investment casting expensive?
Simply so, what earns investment casting?
Investment casting is a manufacturing process in which a wax pattern is coated with a refractory ceramic material. Once the ceramic material is hardened its internal geometry takes the shape of the casting. The wax is melted out and molten metal is poured into the cavity where the wax pattern was.
Beside above, how accurate is investment casting? Detail and Accuracy Investment casting can achieve excellent detail and accuracy – in +/- 0.005 inch per inch range. Very little additional machining is necessary for details and features.
Then, what are the advantages of investment casting?
Advantages of Investment Casting
- Smooth Finish. Investment casting uses a ceramic mold that can produce a much smoother finish, typically averaging 125 RA surface finish as cast.
- Faster Production.
- Tight Tolerances.
- Affordable Tooling.
- Vast Size Range.
- Material Variety.
Why is it called investment casting?
Overview of Investment Casting Molten metal is then poured into the mold's cavity, essentially replacing the cavity's wax with metal. It's called “investment casting” because the mold pattern used in this casting process becomes “invested” with the liquid refractory material.
