What is Investment Casting?
Investeringsstøbning, also known as precision casting or lost wax casting, is a manufacturing process in which a wax pattern is used to shape disposable mold. A wax pattern is made in the exact shape of the item to be cast. This pattern is coated with a refractory ceramic material. Once the ceramic material is hardened, it is turned upside-down and heated until the wax melts and drains out. The hardened ceramic shell becomes an expendable investment mold. Molten metal is poured into the mold and is left to cool. The metal casting is then broken from the spent mold.
The investment casting process allows for the production of complex parts with high accuracy and surface finish, making it suitable for industries that require intricate components, såsom rumfart, Automotive, and medical equipment manufacturing.
Investeringsstøbningsprocessen
The investment casting process, Også kendt som tabt-wax casting, involves several steps to create metal parts with high precision and intricate details. Here is an overview of the investment casting process:
1、Pattern Creation
The wax is injected into the metal mold to form a one-off wax pattern that is identical to the metal part being produced. Several patterns are connected to a central wax pouring system to create tree-like components.
3、Pouring
The mold is preheated in a furnace to approximately 1000°C (1832°F) and the molten metal is poured from a ladle into the gating system, filling the mold cavity. Pouring is typically achieved manually under the force of gravity, but other methods such as vacuum or pressure are sometimes used.
5、Casting Removal
After the molten metal has cooled, the mold can be broken and the casting removed. The ceramic mold is typically broken using water jets, but several other methods exist. Once removed, the parts are separated from the gating system by either sawing or cold breaking (using liquid nitrogen).
2、Mold Creation
The "model tree" is dipped into a slurry of fine ceramic particles, coated with coarser particles, and then dried to form a ceramic shell around the model and gating system. This process is repeated until the shell is thick enough to withstand the molten metal it will encounter. The shell is then placed in an oven and the wax melts, leaving behind a hollow ceramic shell that serves as a one-piece mold, hence the name "lost wax" casting.
4、Cooling
After the mold has been filled, the molten metal is allowed to cool and solidify into the shape of the final casting. Cooling time depends on the thickness of the part, the thickness of the mold, and the material used.
6、Efterbehandling
Oftentimes, finishing operations such as grinding or sandblasting are used to smooth the part at the gates. Heat treatment is also sometimes used to harden the final part.
