Custom Aluminum Die Casting Services

St. Clair Die Casting provides full service, custom aluminum die casting, tool design, and precision CNC machining. Utilizing precise manufacturing techniques, advanced automation and robotics, we provide complete project management, and ongoing tool support.

With the ability to work with A380, A360 or A383-aluminum, St. Clair can specialize in high-pressure die casting, which utilizes vacuum assist and squeeze pin technology to minimize porosity. Casting processes employs dry vacuum impregnation where required and clamping pressures from 450 to 1,000 tons. Other value-add operations include machining, drill/tapping, roto-blasting, heat treating, painting and clear or dark anodizing.

A complete quality control system is in place and includes process monitoring and inspections such as automated CMM with magnetic tip as well as spectro-analysis. Other offerings include mold flow and finite element analysis, thermal stress, and leak/pressure test air decay.  St. Clair is committed to providing the highest quality custom aluminum die casting services and can be best exemplified by our many satisfied customers.
