Services

AI illustration of 3d sand printing.

3D sand printing

Uses binder-jet printing to build sand molds and cores from CAD geometry. The process supports intricate internal passages and tooling-free mold production; foundries use the printed sand components to cast the final metal parts.

AI illustration of foundry tooling.

Foundry tooling

Manufactures patterns, core boxes and related tooling for foundry production. Tooling development combines digital design with machining and practical casting-process requirements for repeat use in a foundry.
