Steel investment casting, or as popularly known, Precision Casting, Lost Wax Casting is a process of manufacturing in which molten metal, which is steel is poured into a mould to produce the required industrial component. Although very similar to other investment casting processes such as sand casting, die casting, etc. Considering the many benefits of steel investment casting, it makes it for a preferred choice for many machine manufacturers.
Steel Investment Casting involves various processes and steps until the final production of a component begins.
Stainless Steel Investment Casting Process
Wax copy is sprued with a tree-like structure. This is done to make a path for the molten metal to flow and help the air escape through this thin passage. The sprued wax copy is dipped in the silica slurry & stucco. The whole assembly is then allowed to dry and get harden.
The dipping process is repeated multiple times to attain the desired thickness of the shell coating. The inside of the shell coating is hollow and layered with fireproof material.
The shell is hardened and the wax inside the shell is melted. The shell is then cooled and tested by flowing water through it to check the presence of any cracks. If cracks are present, then they are repaired with a thick paste and then allowed to dry.
Step one: Pattern OR Tool Making
Pattern making is the very first step in steel investment casting. In order to achieve precision, tooling process is undertaken to achieve the exact pattern of the desired component. This process uses exact details as of the finished part, except it provides allowance for thermal contraction/shrinking. Patterns are typically made of wax using a metal injection die. Usually, steel investment casting manufacturers charge one-time pattern making or tooling cost from the clients during the sample making process, which is later on reused for final production process.
Step two: Pattern Mounting
A wax pattern making is a second step in steel investment casting. One creating patterns takes place. A wax pattern is made by injecting wax into the pattern, whereby a model is generated with exact dimension of the desired end product. This step is repeated for every wax pattern, which is later on assembled one by one onto the spruce to create a wax tree. Depending on the size and configuration of the desired end component, multiple wax patterns may be created using a single tree. The tree is then hung for drying at room temperature.

Investment casting is in a lot of ways similar to lost-wax casting and it is an old metal making process to duplicate the features of the original sculpture and then cast multiple identical metal parts that are an identical match to the sample metal part.Intricate detailing and designing are achieved successfully through the process.An original wax model similar to the sample metal part is made and then mild making is required.
An outer rigid mild is prepared by dipping the wax pattern in ceramic slurry plus sand-like stucco.Dipping in the slurry is repeated multiple times to attain the desired thickness of the shell.
This outer mild is the exact negative of the original wax pattern.This wax and mild assembly are spruced with a tree-like structure.
The shell-coated wax assembly gets hardened and then the wax is melted out of it by heating the assembly.The shell is cooled and tested to check if it contains any cracks in it, the cracks are filled with a thick paste.Reheating of the shell helps in removing traces of moisture from it.
Then the hot and melted metal is poured in the preheated shell carefully.
Benefits of Investment Casting:Faster Production- Investment castings cuts the labour time and increases the speed of production as it does not require much assembling after casting.Tight Tolerances- Investment castings have higher tolerance that reduces the amount of machining required.Smooth Finish- Mostly a ceramic mold is used in investment casting for a much smoother finish.Less Casting defects, improve quality- Investment casting provides good quality products without defects.Less Waste at competitive manufacturing cost- Investment casting needs less expensive apparatus which in turn keeps the costs low, also it requires very little machining that helps in minimizing material waste.Customizable size without quantity limitation- Investment casting allows both small and large quantities and cost is mostly same for both the cases.Reheating of the shell helps in removing traces of moisture from it.
