The Benefits of the Tilt Pour Permanent Mold Casting Process

Stahl Specialty uses its decades of experience in producing high quality aluminum castings to select the optimal process to produce your product. We developed the tilt process that was described above. Another is the static pour process, which offers two main advantages:
Static Pour Process
Stahl specializes in complex castings, many of which are semi-permanent mold, meaning that there is a sand core that provides a hollow region within the component. There are many purposes for cores, yet there are also many challenges to produce high yield cast products. Stahl understands the challenges which include attention to the details that include managing wall thicknesses, including allowable core shift; managing outgas of core materials; surface finish; and maintaining a pressure-tight product.
Stahl has significant in-house capacity and a fleet of machines to produce high volumes of small or very large cores. Capabilities include Hot cured (Shell) and Cold cured (SO2) and flexibility in grain sizes and resins.
Stahl’s castings are used on diesel engines that carry a million mile life expectancy before an overhaul. The loads are extreme, and Stahl has a proven track record in producing highly cored, pressure-tight and lightweight engine products.
A great example of a structural and pressure-tight aluminum casting is this cover for a 5.0L diesel engine for a prominent new pickup truck. This cover incorporates six complex sand cores to create oil, coolant, and water passageways. The ability to produce this casting provides confidence to the leading edge engine designers.

Stahl has the largest fleet of large 48 x 60 machines, and rotaries for high volumes. Examples of large permanent mold castings are found on 15L engines for commercial trucks – front covers, oil pans and pressure-tight fuel pump housings.
