Precision Investment Casting, also referred to as lost wax casting, is a process in which metals are casted into different shapes using wax and ceramics to act as the mould for the casting. This is one of the oldest known techniques for metal casting and has stood the test of time over centuries.

It finds usage in various industries like firearms industry, energy industry, gas and oil and even food industry. While many debate upon the strength and durability of this form of casting, doubting mainly that this method might provide weaker metal shapes as compared to forging or metal fabrication, these doubts have been laid to rest since aerospace, defence and medical fields have trusted equipment that are made from Precision Investment Casting.

WHAT IS THE PROCESS FOR PRECISION INVESTMENT CASTING?

As mentioned earlier, the process for Precision Investment Casting requires wax and ceramics to be the mould for the main metal. This is done in a very simple yet precise way (hence the name) and the steps are:

? Pattern Formation –Manufacturing of the wax pattern is the very first step involved in investment casting. Here it should be mentioned that wax is preferred over plastic, because wax melts easily and can be reused for another casting which is again a beneficial point from costing aspect. Special aluminium moulds are made to cast the pattern and this requires some trial and error, because factors like shrinking of the wax, the ceramic or even the metal should be incorporated.
