<\/p>\n[vc_row][vc_column][vc_column_text]Investment Casting Vs. Sand Casting<\/p>\n
<\/p>\n
Two of the most used methods of casting are precision or investment casting and sand casting.<\/p>\n
These techniques have evolved and show many differences when applied in various industries to produce metal components.<\/p>\n
Sand casting and investment casting\u00a0are used to make metal parts in various industries.<\/p>\n
The two casting methods use almost a similar principle: pouring molten metal into molds and leaving it to cool.<\/p>\n
However, investment casting and sand casting\u00a0are remarkably different in many ways.<\/p>\n
This article compares investment casting and sand casting\u00a0and outlines the differences between the two oldest casting techniques.<\/p>\n

Investment casting, also known as lost wax casting or precision casting, is the oldest casting technique used to make metal components.<\/p>\n
The process involves using molten metal and molds with the desired shape of the final product.<\/p>\n
The entire investment casting process can be summarized as follows:<\/p>\n
Investment casting often involves using hot wax to make various tree patterns.<\/p>\n
Sprues and wax runners are preferred, and this can be used to produce more than one part.<\/p>\n
The patterns make a tree, absorbed in a ceramic slurry that makes it hard enough once it cools and dries.<\/p>\n
Once dry, the tree and wax patterns are passed through immense temperatures to melt off the wax.<\/p>\n
When the wax and sprues melt, they create hollow tubes that guide the flow of the molten metal into the mold.<\/p>\n
The metal is poured into the mold and left to cool and solidify.<\/p>\n
