What is Investment Casting?

What is Investment Casting topgrid
  • Investment casting, also known as lost wax casting, is a manufacturing process that uses a wax pattern to create a mold cavity.
  • The wax pattern is coated with a ceramic slurry, which is then fired to create a hard mold. The wax pattern is then melted out, leaving behind a mold cavity that is the exact shape of the desired part.
  • Molten metal is then poured into the mold cavity and allowed to solidify. Once the metal has solidified, the mold is broken away and the part is ejected.

Investment Casting Process

Investment casting is a versatile manufacturing process that can be used to produce a wide range of parts, from simple to complex, and from small to large. Investment castings are typically strong, precise, and have a good surface finish.

Investment Casting Process Topgrid

The investment casting process can be broken down into the following steps:

1. Creating the wax pattern: A wax pattern of the desired part is created using a variety of methods, such as injection molding or 3D printing.

2. Assembling the wax pattern: The wax pattern is assembled onto a sprue and gate system. The sprue and gate system is a channel that allows the molten metal to flow into the mold cavity.

3. Coating the wax pattern: The wax pattern is coated with a ceramic slurry. The ceramic slurry is a mixture of water, sand, and a binder. The ceramic slurry is applied to the wax pattern using a variety of methods, such as dipping or spraying.

4. Firing the ceramic mold: The ceramic mold is fired in a furnace to harden the ceramic slurry.

5. Removing the wax pattern: The wax pattern is melted out of the ceramic mold using a variety of methods, such as steam or hot water.

6. Pouring the metal: Molten metal is poured into the mold cavity. The molten metal is typically poured using a gravity pour or a vacuum pour.

7. Cooling and solidification: The molten metal is allowed to cool and solidify in the mold cavity. This typically takes a few seconds to a few minutes, depending on the size and complexity of the part.

8. Breaking away the mold: The ceramic mold is broken away to reveal the cast part.

9. Finishing the part: The cast part may undergo some finishing operations, such as machining or heat treatment, depending on the requirements.
