Casting is one of the oldest manufacturing techniques dating back to 1838. While the basic casting process hasn’t changed much, today’s machines are more advanced and with improvements in technology, there are several different ways to reach your end product. Two of those common ways are die casting and investment casting. Let’s take a look at differences between the two as well as talk about who the best provider of investment castings is.
When die casting a part, molten metal is injected into a hardened steel die cavity. When the metal solidifies, it is ejected from the tool and the process is repeated. The hardened steel mold is capable of creating anywhere from 150,000 shots to over a million shots before it would need to be repaired or replaced.
The investment casting, or lost wax process is typically more time consuming then die casting. In this process, a wax prototype of your part is made and then repeatedly dipped into liquid ceramic. The ceramic hardens and then the wax is melted out leaving you with a ceramic mold. After the ceramic mold is made, molten metal is poured into the ceramic cavity where the wax once was. Once the metal solidifies, the ceramic mold is broken and removed leaving the metal casting.
