There are numerous applications where investment castings are predominantly used – aerospace, power generation, firearm, automotive, military, commercial, food service, oil and gas, and energy industries use these components the most. The global investment casting market size was estimated at USD 14.35 billion in 2018 and is expected to grow at a CAGR of 4.6% till 2025 as per a market research report by Grand View Research. It offers weight reduction, less machining, improved delivery time and lower inventory carrying costs. Transmission forks are now manufactured using investment casting instead of forging and complex machining. High temperature applications are also common, which includes parts for the oil & gas drilling, automotive, aircraft, and military industries.

Parts that are typically made by investment casting include those with complex geometry such as turbine blades or firearm components. Investment casting process, also termed as a lost wax process, is relatively simple, which enables rapid production rates while ensuring consistent dimensional accuracy. Investment castings are one of the most popular production methods for metal parts today.
