Why are Investment Castings Occasionally Called Lost-wax Castings?

[Caiden]

Indeed! The term investment casting has its roots in the historical use of wax patterns as an investment or price in the casting method. Craftsmen would invest moment and re sources into generating sophisticated wax patterns, which were then utilised to produce metal castings. Over moment, this procedure evolved into the modern day precision casting method we exploit today, but the term stuck. It's interesting how the terminology reflects the historical origins of the process<sp>. Have you come across any other terms in manufacturing that get historical significance like this?
