What Joy-Mark does

Joy-Mark, Inc. is a privately held U.S. manufacturer of foundry consumables founded in 1977 and headquartered at 5935 S. Pennsylvania Ave., Cudahy, Wisconsin. The company produces a comprehensive portfolio of feeding aids (insulating and exothermic riser sleeves, neckdowns, blind/dome and spherical risers, hot toppings, exothermic cores, and SPOT risers in standard and fluorine-free formulations), ceramic foam filters (zirconia, alumina, silicon carbide, and specialty materials including the CeraCat+ preheat-free grade), and specialty products such as ladle liners, skimmers, slag rings, fiber gating tiles, pouring sprues, Ceratec ceramic molding media, and VOC-compliant pattern sprays. Manufacturing is centered on two highly automated production facilities in Cudahy, WI using vacuum forming and mixing processes, with riser sleeves available from 1" to 42" in diameter and standard heights up to 12".

The company serves primarily the foundry industry across molding, melt deck, cleaning room, and heat treating applications, with secondary exposure to concrete form release. Through the 2013 formation of GTP Joymark, LLC — a joint venture with German partner GTP Schaefer GmbH — Joy-Mark holds exclusive U.S. production rights for advanced high-density exothermic risers with precision-controlled insulating formulations and integrated metal breakers. Products are sold via a combination of direct sales and a national distributor network covering the U.S., Canada, and Mexico, with growing export sales into South America and Europe. No public revenue, funding, or headcount disclosures are available; the company operates as an independent, privately held corporation.
