Orem home to one of nation’s largest diamond manufacturers

OREM — There are thousands of carats of diamonds flowing through Utah County, but the majority don’t end up on anyone’s finger.

US Synthetic in Orem is the nation’s largest manufacturer of polycrystalline diamond. The company makes long-lasting diamond inserts for tools used in mining, energy production, and exploration and other manufacturing fields. It was started more than 30 years ago by Louis Pope.

According to company president Rob Galloway, 50 percent of all drilling globally is done with US Synthetic equipment.

US Synthetic takes carbon-based synthetic diamond grit and applies heat and pressure to create the diamonds for manufacturing use. It puts about 10 carats of synthetic diamond in every product it makes.

“Synthetic diamond is a super material and we’re constantly looking for new applications for it,” Galloway said.

Residual stresses in PDC cutters arise from the difference in thermal expansion between the polycrystalline diamond layer and the supporting tungsten carbide substrate after sintering at high pressure and temperature. If not managed correctly, these stresses can significantly reduce the toughness of the cutters, especially as the diamond-layer thickness increases.
