Short Description:

Lost wax casting is a casting process that uses a wax pattern to create a ceramic mold for creating a part or product design. It has been known over the years as lost wax or precision casting due to its accuracy in recreating parts with precise tolerances. In modern applications, lost wax casting is referred to as investment casting.
The process that makes lost wax casting unlike any other casting method is the use of a wax pattern to create the initial mold, which can have intricate and complex designs.
The lost wax casting process as below:
Creation of the Die →Die Producing the Wax Pattern→Wax Pattern Tree→Shell building(Ceramic Coated Wax Pattern)→Dewaxing→Burnout→Casting→Knock Out, Divesting, or Cleaning→Cutting→shot or sand blasting→

The Advantages of Lost wax Casting
Smooth Finishes
The roughness average (RA) of a lost wax cast part averages around 125, which is the average of the peaks and valleys on the finished surface.
Tolerances
The biggest advantage of lost wax casting is the tight and accurate tolerances that have a standard of ± 0.005. CAD computer designs are accurately and precisely recreated to exactly fit the final application.
Variety of Metals
There are very few limitations to the types and kinds of metals that can be used in lost wax casting. The types of metals include bronze, stainless steel, alloy steel, iron, and copper
Size Range
As there is little limitation on the types of metals used in lost wax casting, the same applies to the size of parts to be formed. The range of sizes starts with small dental implants up to complex aircraft engine parts weighing thousands of pounds. The size and weight of lost wax cast parts is dependent on the mold handling equipment.
Affordable Tooling
Lost wax casting uses less expensive equipment, which makes it less dangerous. Also the tooling cost is cheaper.
