This is because of the many benefits of lost wax casting. For instance, the process is mainly used since it allows manufacturers the flexibility to produce parts with complex designs, forms, and shapes without the need for post-processes.<\/p>\n<p>The advantages of lost wax casting include:<\/p>\n<h2><span id=\"_Smooth_Surface_Finish\">\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Smooth Surface Finish<\/span><\/h2>\n<p>The lost wax casting process uses molds made from a ceramic slurry. This means that the final piece does not possess any rough finish and can be shipped directly without post-processes.<\/p>\n<h2><span id=\"_Production_Turnaround\">\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Production Turnaround<\/span><\/h2>\n<p>One of the vital factors of any manufacturing process is the lead time. In this case, lost wax casting does not require any post-processes or machining on the final piece. This means that the lead time is greatly reduced. Accordingly, further handling and labor are also minimized.<\/p>\n<h2><span id=\"_Affordability\">\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Affordability<\/span><\/h2>\n<p>The initial investment involved in lost wax casting is usually on machinery. However, the process uses less costly equipment, which reduces the overall cost of production. This factor also makes lost wax casting less dangerous.<\/p>\n<h2><span id=\"_Close_Tolerance\">\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Close Tolerance<\/span><\/h2>\n<p>One of the most significant benefits of the lost wax casting process is that it ensures tight and precise tolerance. The process uses CAD designs that are more accurate and allow a tolerance standard of \u00b1 0.005.<\/p>\n<h2><span id=\"_Wide_Variety_of_Materials\">\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Wide Variety of Materials<\/span><\/h2>\n<p>Another factor that makes lost wax casting a popular casting process is that it can be used with a wide range of both ferrous and non-ferrous metal and metal alloys. The process gives lost wax casting manufacturers many options when manufacturing metal parts.<\/p>\n<h2><span id=\"_Size_Range\">\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Size Range<\/span><\/h2>\n<p>The lost wax casting process has fewer limitations regarding the size of parts that can be manufactured. The components range from small dental implants to highly intricate jet engine parts. However, the size of a lost wax casting part depends on the mold handling equipment used.<\/p>\n<h2><span id=\"_Overall_Production_Cost\">\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Overall Production Cost<\/span><\/h2>\n<p>Since the lost wax casting process does not require post-process, it reduces the need for added human resources and costs.
