APU Bell Inlet
APU Bell Inlet

At Precision Metal Products, we specialize at providing low volume, high mix manufacturing services to customers in the aerospace industry. Producing the bell inlet shown here, which featured dimensions of 12" in diameter and 4" in length, required diligent planning and scheduling for the execution of multiple fabrication and assembly processes.

We formed the Poroplate® inner skin and stainless steel outer skin pre-forms on our punch press, then moved them to the spinning lathe to create the axial geometry. Our technicians then used a laser to trim them to a tight ±.005" tolerance. We rough machined the forged ring and welded to the inner liner, then used an adhesive film to bond the honeycomb between the inner and outer liners. Additional operations consisted of finish machining the forged ring, fiberglass layup on the external skin, masking, and painting.

This project showcases our ability to use multiple materials and use a large mix of manufacturing, assembly, test, and inspection processes to produce high-integrity, critical components for demanding applications.
