Still the Best? 3 Reasons to Choose Investment Castings

With all the different manufacturing methods out there for stainless steel, it is surprising that investment casting still exists. Investment casting is one of the oldest forms of metalworking, and requires many steps that other metalworking industrial manufacturing processes do not. With investment casting, first you have to make a mold of the desired product a little bigger than the desired size of the finished product. Then you have to make a wax cast of that part. The cast is then covered with a ceramic mold material. The wax is melted, and then metal is poured into the ceramic mold. After cooling, the ceramic mold is broken and the metal part is exposed.

So since there are so many other metal forming methods out there, why should an industrial company continue to use investment casting for stainless steel metals?

Surprisingly enough, investment casting actually has many benefits over other forms of metal working and shaping. Even though the process is thousands of years old, many stainless steel investment casting companies specifically choose to use investment casting for the benefits that it provides. Some of the benefits that investment casting can offer include:

Reduced machining time: Since stainless steel investment casting companies use molds that look precisely like the finished part, there is much less machining and modification that the metal has to go through after the molding process. This can save manufacturing companies significant time and money throughout the manufacturing process.

Customizable lot size: Because investment casting is done one part at a time, or in small batches, it is easy to customize the amount of products that are produced using the casting method. Customers can choose to make large or small product lots without costing the manufacturing plant significantly extra.

Improved quality: The investment casting molds are created with a high attention to detail. This improves the quality of the metal and prevents the weakening of the metal through overworking.
