Plywood Chair Shell Manufacturing: Molding, Drilling & Finishing

The video shows the complete manufacturing of plywood chair shells from raw material to finished part at MSDA's woodworking workshop. Workers first stack veneer sheets onto laminated boards by grain direction and ply count; the stacked panels are then placed between dies and hot-pressed into chair back and seat shells with ergonomic curvature, where temperature and pressure stability directly determines panel adhesion and shape consistency. The molded shells are drilled with precise mounting holes and connection interfaces by CNC equipment, followed by edge trimming to remove burrs; drilling accuracy determines hole alignment in final assembly. Qualified shells, verified by visual and dimensional inspection, proceed to the assembly line to be combined with metal frames and foam upholstery into finished chairs.
