Kore Mart

What Kore Mart does

Kore Mart is a privately held US foundry supplies company founded in 1981 and headquartered in Hamburg, Pennsylvania. The company designs, manufactures, and supplies custom foundry cores, 3D-printed sand cores and molds, and a broad line of consumables (resin coated sand, riser sleeves and feeding aids, foundry resins, and raw sands) to metal casting foundries across the United States. Kore Mart also operates the country's only foundry sand reclamation service, restoring used core sand and molds for reuse.

The company's technology stack centers on Ex One S-Max additive manufacturing for 3D-printed sand cores and molds, enabling complex single-piece geometries that eliminate assembled core work and reduce tooling requirements. Custom resin coated sand blending is supported by trained technicians and an on-site state-of-the-art sand testing lab, and an in-house truck fleet handles just-in-time delivery. These capabilities collectively target casting defects, long lead times, environmental waste from spent sand, and inconsistent product quality at customer foundries.

Kore Mart operates a direct-to-foundry B2B model with quote-based pricing, technical sales support, and dedicated customer service. The company sells a mix of one-off custom cores (including 3D-printed and conventional cold-box/air-set), recurring consumable products, and professional services such as sand reclamation. Public materials report consistent double-digit revenue growth over the past ten years, driven by reinvestment in modernization and capacity expansion rather than disclosed external funding.
