Title: Innovations by Rachel R Pineda
Introduction
Rachel R Pineda is an accomplished inventor based in Santa Maria, California. She has made significant contributions to the field of investment casting, holding three patents that showcase her innovative approach to material composition and processing techniques.
Latest Patents
Her latest patents include "Phosphate investment compositions and methods of use thereof." This invention describes methods for making molding casts through a process known as investment casting, utilizing a novel phosphate-bonded material. The composition consists of mono-ammonium phosphate (MAP), magnesium oxide, and silica filler, which can be quartz, cristobalite, or a mixture of both. Pineda's research has revealed that the precise control of these components significantly affects gas permeability, set time, cast smoothness, and cast softness. A standout feature of her new investments is the reduced mold fabrication and processing time, attributed to their high gas permeability. The investments can be placed in a burnout furnace while still wet and can be rapidly heated to the firing temperature. The resulting casts can be easily broken by sandblasting with glass beads, and molds made from these casts exhibit smooth surfaces, free from visible inclusions and defects.
