What Ransom & Randolph does

Ransom & Randolph (R&R) is a 152-year-old specialty materials manufacturer that produces investment casting consumables for four end markets: ceramic shell foundries (industrial/aerospace/automotive), dental laboratories, jewelry manufacturers, and solid-mold/bronze art casters. Its product portfolio spans binder systems (Primcote, Customcote, Keycote, Matrixcote), ready-to-use fused silica slurries (SuspendaSlurry), refractories and core materials, dental stones and duplicating materials (Glastone, FiberStone, Multiflex), jewelry investments (Ultra-Vest, Plasticast PT, Argentum, Aurum), solid-mold investments, glass-casting investments (Glass-Cast), cobalt-chrome alloys (Neoloy), and a growing line of 3D-print-to-cast resins and abrasives. Production is anchored at the Maumee, Ohio global headquarters, with European manufacturing and blending in Böhmte and Wurzen, Germany, a commercial office in Rötha, and a network of US and UK warehouses and authorized distributors reaching 30+ countries.

R&R makes money by manufacturing and selling consumable materials on a quote-based model, supplemented by a small e-commerce storefront. Go-to-market combines direct regional sales managers in the US and EU with global authorized distributors across ceramic shell, dental, and jewelry categories. The company monetizes primarily through volume sales of process-qualified consumables, with technical service, foundry consultation, and laboratory testing as supporting value drivers rather than standalone revenue streams. Customers are reported across industrial foundries, dental labs, jewelry houses, and art casters, with no public revenue split or major enterprise logo disclosed.

Since 2021, R&R has operated as a privately held portfolio company of PMC Capital Partners following its divestiture by Dentsply Sirona. Under PE ownership, the business has executed a rebrand (2025), refreshed its C-suite, and pursued a roll-up strategy acquiring product lines from Whip Mix (2024) and Talladium (2026), and acquiring emwerk GmBH in Germany (2026), while launching the P2C dental and jewelry Print-to-Cast platforms and entering dental 3D printing resins and fused alumina abrasives. Capacity has been expanded at Maumee with a 50% production expansion in 2023 and a 2025 rail and land investment, positioning the company for continued product-line consolidation and digital-workflow adjacencies.
