This surgical research part plays a role in facilitating animal brain surgery. Investment casting replaced a costly non-ferrous alloy fabrication with a stainless and corrosion- resistant Type 303 steel. All major details are cast to finish dimensions and the parts are completed at tremendous cost savings. The only secondary operation required is reaming of three holes and buffing.

this component for a measuring instrument is now investment cast to eliminate costly sawing, turning, milling and drilling that was necessary when it was machined from solid stock. After investment casting, only a simple reaming operation of one hole is required. Savings? Plenty!


How Increased Precision Can Cost Less By Fred Meeder

The key to precision reproduction was found by investment casting this ornate piece. Faithful duplication of the intricate detail and smooth surface was mandatory. The keys were originally made as malleable iron cast blanks, requiring costly milling in the tumbler area. After pressing into a handle, additional grinding and buffing were needed for appearance. As an investment casting, the keys are now produced as a one-piece unit in three sizes from either stainless steel or brass ... all using the same tooling. Milling is no longer required. The only additional operation now is light buffing. Investment casting opened the door to faithful reproduction at greatly reduced cost.
