The invention relates to a system and method for the automated spin-casting production of molded articles. The system includes a casting turntable and a processing turntable which are rotatively mounted, immediately adjacent to one another. The casting turntable has several spin modules mounted thereon for rotatively supporting mold assemblies. Casting preparation and pouring mechanisms are mounted around the periphery of the casting turntable. The turntable indexes the mold assemblies and positions the assemblies for preparation, pouring and solidification of the cast products. The processing turntable receives the mold assemblies and solidified castings from the casting turntable. Multiple processing stations are mounted around the periphery of the processing table for the removal of the castings from the mold assemblies and preparation of the mold assemblies for additional casting operations. The mold assemblies are returned to the casting table from the processing table for additional casting processes.

A valve stem seal assembly includes a rigid cylindrical shell and an annular resilient seal body contained entirely within the shell. Integral to the seal body is a frustoconical sealing element adapted to engage a valve guide of an internal combustion engine. The sealing element converges radially inwardly, and upon installation of the assembly on a valve guide the outer surface of the sealing element bends further radially inwardly to effectively seal the top surface of the guide. The seal body includes a stem sealing aperture, which in one preferred embodiment is designed to engage the valve stem without a spring. In a same or similar embodiment, the shell contains a circumferential array of tangs for retention of the assembly on the guide.
