What is investment casting?
Using the additive process of investment casting, liquid metal is poured into a mold and solidified into a part. Due to the liquid’s ability to mold quickly and set itself into the final shape, extensive subtractive machining procedures are not required.
An effective method of casting small to medium-sized components is using the investment casting process.
- There are six investment casting steps as follows:
- Creating the pattern
It uses a pattern that is similar to the finished part in every way except for a provision for thermal contraction.
- Mounting the wax pattern & creating
The gate and runner metal delivery system is constructed using a wax template that has been developed, together with other wax components. Depending on the dimensions and configuration of the desired finish component, multiple wax patterns may be processed using a single tree. A wax pattern may be processed using a single tree, depending on the dimensions and configuration of the desired finish component.
- Creating the mold shell
The ceramic shell’s residual wax is extinguished in a furnace. The remaining wax pattern and gating material have now been eliminated, leaving only the ceramic mold with the cavity mold to the shape of the required cast object.
The strength and stability of the ceramic material are also increased during this high-temperature procedure. Additionally, it aids in reducing the interaction between the metal and shell during pouring.
- Wax removal
To remove the majority of the wax, the entire assembly is placed in a steam autoclave.
- Melt & cast
The metal casting is produced by heating the mold to a certain temperature and filling it with molten metal.
This method allows for the production of almost any alloy. According to the alloy chemistry, either air melting or vacuum melting may be used. Vacuum melting is typically used when an alloy contains reactive components.
- Finishing
Once the casting is cooled to the proper temperature make the mold separate. The casting’s gates and runners are removed, and if other post-processing steps like sandblasting, grinding, or machining is required to complete the casting’s dimensions, they are done so.
For us, describing a company as a pure investment casting company is almost impossible. Consider that investment casting is always used in combination with particular products or finished designs. Investment casting firms, in general, are companies that manufacture, sell, export, or provide investment casting services.
