From innovative R&D to build-to-print production — engineering, specialty material sourcing, CNC machining, wire EDM, and assembly under one roof.

















From aerospace to robotics, we manufacture high-tolerance, critical components for industries that demand absolute precision and zero compromise.
Some customers need an engineering partner. Others need exact execution. We're built for both.
Our engineers work alongside your team on R&D, value engineering, design-for-manufacturability, casting development, and material selection — then carry the design into production.
We execute exactly to print, with disciplined turnaround, full traceability, and inspection documentation on every part.
Each tied to a unique part number with a proven operation sheet on file
Tolerances to half a thousandth of an inch
Disciplined process, reliable outcomes (based on 2025 third-party audit)
From one-off replacements to large-scale production, QSD develops a reliable path through material sourcing, machining, inspection, and delivery.
