Spin forming

Engine inlet lip skins using spin forming and post spin processes

We manufacture 100% of the lip skins for the Boeing 737 Max at a new purpose built lip skin manufacturing facility in Orangeburg, South Carolina.

Inspired by the pioneering use on the 787 for drag reduction, the laminar flow lipskin for the 737 MAX’s CFM Leap 1B engine nacelle is made from a one-piece, spun-formed sheet of aluminum.  The lip skins offer a weight reduction and generate a laminar flow surface that reduces drag and improves aerodynamic performance.
