Ransom & Randolph was founded in 1872 on the principles of honesty, high product quality and superior customer service.

R&R’s initial markets included supplies, instruments and furniture for barbers, doctors and dentists. Since 1900, R&R has pioneered many new and revolutionary products for

industrial, jewelry and dental applications. In 1964, R&R was purchased by DENTSPLY International and began operating as a DENTSPLY division. Twenty years later, the dental business was transferred to other DENTSPLY divisions, allowing R&R to concentrate solely on the precision investment casting business.

Today, the R&R team remains dedicated to the founding principles. With a strong commitment to manufacturing, quality, technical service and customer support, Ransom & Randolph has become the worldwide leading supplier of investment casting materials.
