Top 5 Precision Investment Casting Manufacturers

Author: Date Published: May 23,2024

Precision Investment Casting, also known as lost wax casting, stands as a cornerstone in the realm of metal fabrication, offering intricate solutions for diverse industrial needs. This process begins with the meticulous creation of wax patterns, and exact replicas of the desired components. These wax patterns are then coated with a ceramic shell to form molds capable of withstanding high temperatures. Once the ceramic shell has dried and hardened, the wax is melted and drained out, leaving behind a negative impression of the desired parts within the ceramic mold.

Subsequently, molten metal, typically aluminum, steel, or various alloys, is poured into the ceramic molds. The metal solidifies within the mold cavity, assuming the final shape. Upon cooling and solidification, the ceramic shell is fractured, revealing the metal castings.

Finished parts may necessitate additional post-processing techniques such as machining, polishing, or heat treatment to meet specified requirements.
