Die Casting

High Pressure Die Casting for Complex Parts

Die casting offers the ability of casting complex and near net shapes at an economical price. Tighter tolerances and precise geometry can be cast, reducing finishing and machining operations.

Aluminum Die Casting Process

The upfront tooling investment can be higher than other casting processes, therefore, high pressure die casting is typically used for higher volume casting applications. The benefits of the die casting process are that it can produce castings with thinner wall sections, holding tighter casting tolerances and achieve a better surface finish than other casting methods. 

Le Sueur Incorporated has 12 Die Casting Machines having clamp capacities ranging from 250 to 1600 tons. We offer a large range of aluminum casting alloys including 360, 380, 390 and 413 and specialize in dimensionally complex and pressure-tight applications. LSI has perfected a proprietary technique of using Squeeze Pin Technology to achieve leak-free die castings.
