Sandcasting Molds & Cores Printed Directly from CAD

ProMetal RCT™ printers selectively dispense micro-droplets of foundry-grade resin into paper-thin layers of specially engineered permeable casting media. This additive process creates complex sandcasting cores and molds direct from CAD data, eliminating the thousands-year-old requirement of a physical pattern to create a core or mold. The process produces extremely accurate, uniform cores and molds rapidly, reducing the typical lead time for metalcastings by as many as twelve months. The flexibility to modify and customize mold designs is presently used to improve casting performance, reduce casting weight, and add complexity to cast components.

The ProMetal® RCT S-15™ is suited for foundries and design facilities. The ProMetal S-15 manufactures even the most complex molds and cores directly from CAD. The ability to cast in hours without hard tooling improves the entire casting process chain.
