LeClaire Manufacturing operates a single-source aluminum foundry in Bettendorf, Iowa, offering sand and permanent mold casting with vertically integrated tooling, CNC machining, heat treating, and solidification modeling. The permanent mold page names cast aluminum torque converter, drivetrain, brake caliper, and master cylinder components for automotive, construction, and heavy equipment manufacturers, plus impellers and hubs for agricultural equipment.

Design engineers review customer casting designs for cost and weight reduction, and gating and risering engineering with predictive solidification modeling removes defects before tooling is cut. That is the same buyer problem the focal offering serves: converting vehicle-program components to lighter aluminum castings with engineering support through production.
