Overview of Investment Casting and Lost Wax Casting Processes

Investment casting, also known as precision casting or lost wax casting, represents one of the most sophisticated metal forming processes available in modern manufacturing. This ancient technique, refined with contemporary technology, enables the production of highly complex Bronze and Brass components with exceptional dimensional accuracy and superior surface finishes. The process begins with the creation of a wax pattern that precisely replicates the final component geometry, followed by the application of ceramic shell coatings that form the investment mold. Once the wax is melted out, molten Bronze or Brass alloy is poured into the ceramic cavity, creating components with tolerances as tight as ±0.1mm and surface finishes comparable to machined parts.
