Cool Stuff Being Made: How Investment Castings Are Made

Here is this week’s “Cool Stuff Being Made”! – “…from aerospace to zippers, a lot things we use and interact with these days are made with investment cast parts. Surgery tools, golf equipment and lots of things that the military use all rely on the investment cast process. The investment cast process begins with plastics (Yes, Mr. Robinson, there “is a great future in plastics!”) to create near net shape metal parts that require minimal surface treatment. Investment cast parts come in all shapes and sizes, from fractions of an ounce to several tones.” Link.
