Investment casting is the process of pouring hot and melted metal into a cast mold to create a part or product. Investment casting is one of the most reliable methods used for forming detailed parts of metal pieces, and is often used to create delicate machine parts used in vehicles and manufacturing processes. However, sometimes basic investment casting is not detailed enough to complete the job. This is where precision casting comes into the picture. Precision casting is aided by computers and detailed machinery to create the most detailed metal parts and pieces possible.
Precision investment casting is the process of creating investment castings with the highest level of detail and customization. The precise nature of the casting enables the manufacturer to create even the most detailed and delicate shapes through the casting process, which is unusual for most casting processes. When you switch to precision investment casting, you will incur the following production benefits:
The metal casting process has changed little in the thousands of years since its original invention. Today’s copper casting companies have invented new machines and casting materials that make the process easier and defects less likely, but in the end, the overall casting process remains the same. First, the copper is melted, then poured into a mold and allowed to harden. After the metal hardens, it is removed from the mold and polished and modified until it reaches the desired shape, texture, and brightness.
I once saw a video about the investment casting process, and I was struck by a few things as I was watching it. First, I was struck by the number of different phases involved in the process of investment casting products. The pattern making phases, the shell coating phases, the casting phase and the shell breaking phase each seem complicated enough without being combined together into one metalworking process. I was also struck by how such imprecise-looking shells could produce casting with such precision. Of course I realize that an investment casting shell will not look particularly well-formed from the outside, but it was still striking to see a precise, intricately-formed casting emerge from the seemingly plain shell.
