A machine shop, not a middleman
SEC.01 / WHO WE ARE
Newtop Group machines custom metal parts for companies that care about the numbers on the drawing. We run Swiss CNC lathes and multi-axis mills in-house, and we measure every lot before it ships.
The parts on this site (drone mounts, pneumatic fittings, fasteners, audio knobs, medical pins, archery components) are work we have actually produced. Send a drawing and we quote it within one business day.
From stainless steel to specialty alloys, we build tailor-made parts that perform in demanding environments: aerospace-grade UAV structures, automotive assemblies, high-pressure pneumatic systems.
