(Costs of these projects > $3 Million) - Successfully reduced raw material costs (> $1 Million) for garage-door opener roll-formed rails by specifying hot-rolled instead of cold-rolled steel along with significant modifications to the steel properties. - Selected, installed, started-up and validated a new 400 MT capacity large-bed (2 x 3 meters) Komatsu press for garage door opener steel chassis progressive stamping. - Successfully headed a project for the high-volume punching of holes without deformation in hollow, very thin-walled aluminum extruded garage-door opener rails. - Responsible for the conceptual creation, construction, installation, debugging and certification of an unique semi-automatic high capacity tubular steel rail multiple cutoff machine instead of an additional rail-forming line. ($1.5 Million capital avoidance achieved) - Started and certified the roll-forming of 3 new steel rail profiles with very tight tolerances (C-rail, C-rail splices and Screw-drive rails.) - Designed and installed a flying coolant-drying system to prevent spotting of galvanized steel rails.
