What DIDION International does
DIDION International is a family-owned US manufacturer of rotary processing machinery for the foundry and metal recycling industries, founded in 1975 by Charles J. Didion and headquartered in St. Peters, Missouri. The company was created to address limitations of legacy vibratory shakeout systems and has remained under multi-generational family ownership, with no external investors or parent company identified in the source data. Its equipment is deployed in at least 42 countries across foundry, smelting, pipeline, and scrap recycling end markets.
The company's core technology centers on patented rotary drum designs that consolidate multiple processing steps into single machines. Its flagship Rotary Media Drum (Mark 5 Series) uses a patented dual-chamber architecture to combine shakeout, sand blending, dual sand screening, casting cleaning, and cooling in one unit. Supporting products include Sand Reclaimers, Scrap Metal Polishers (co-developed with WENDT for the recycling vertical), Sprue Crushers, Dross & Slag Metal Reclaimers, Carbon Separators & Thimble Cleaners, Sand Blending & Cooling Drums, Rotary Dryers, and Rotary Sand Screens, plus a Metal Fabrication Services line covering plasma cutting, welding, and CNC machining. Six registered patents protect the core architectures, including a segmented cast wear liner design claimed to exceed 10 years of service life. Customer outcomes cited include 97% sand reclamation yields, $321,867 of brass recovered in three months at Neptune Technologies, and $4,190.40/hour in savings at Betz Industries.
DIDION operates as a B2B capital equipment manufacturer selling directly to foundries and recyclers via custom quotes, Ex-Works St. Peters pricing in USD, and multi-year contract terms. Go-to-market is enterprise field sales supported by website-driven inbound (didion.com), case-study content marketing, and a light social media presence on LinkedIn, Facebook, X, and YouTube. A secondary revenue stream provides technical assistance and service on a per diem basis plus travel. The company employs 101–250 people, does not disclose revenue, has no subsidiaries, and has not executed any disclosed acquisitions, funding rounds, or restructuring events.

Products and services
- Rotary Media Drums (Mark 5 Series) Patented dual-chamber rotary drums that separate sand from castings while cleaning and cooling metals. Combines shakeout, sand screening, casting cleaning, and cooling in a single machine for foundry operators.
- Sand Casting Separators Rotary equipment that separates sand from castings while simultaneously cleaning and cooling metal parts, featuring wear-resistant alloyed ductile iron liners for foundry operations.
- Scrap Metal Polishers (Metal Polishing Drum) Patented rotary drum that uses tumbling action and an air wash to remove dust, surface contamination, and oxidation from scrap metal, producing brighter, cleaner metals ready for recirculation in recycling and smelting operations.
- Sprue Crusher & Cleaners Rotary equipment that crushes core butts and removes sand from gates, runners, and sprue, producing clean melting stock that increases melting efficiency and reduces slag handling costs for foundry operators.
- Dross & Slag Metal Reclaimers Patented dynamically isolated articulated concentric crusher that liberates and reclaims valuable metallics from large slag and dross chunks using serrated teeth and a high-intensity attrition chamber, for slag-producing foundries and recyclers.
- Carbon Separators & Thimble Cleaners Patented rotary tumbler that efficiently cleans carbon from cast iron thimbles using tumbling action, with segmented alloy wear liners for reduced noise and extended wear resistance, designed for iron foundries and aluminum smelters.
- Sand Reclaimer Patented multi-chamber rotary system that crushes sand lumps, scrubs binder off sand grains, screens sand twice, and separates tramp metal, claimed to deliver the lowest operating cost per ton worldwide for foundry sand reclamation.
- Sand Blending & Cooling Drums Rotary equipment that blends, cools, conditions, screens, and classifies green return sand efficiently, with an open-end design allowing easy loading and integral sand screening, for foundry sand systems.
- Rotary Dryers Industry benchmark rotary dryer with an open-end design for straightforward loading, operating with low horsepower and CFM requirements, featuring a variable jet burner for consistent temperature control, used for drying sand and other materials.
- Rotary Sand Screens Cost-effective rotary screen that blends, conditions, and removes core butts and tramp metal from return sand in one streamlined step, featuring an internal sand distribution system for foundry return sand handling.
