Custom Manufacturing Services for Made-to-Drawing Parts

From prototype to production, Sunmy delivers custom metal and plastic components built to your exact specifications. Our capabilities cover CNC machining, precision turning, casting, sheet-metal stamping, injection molding, tooling development, surface finishing, and assembly.

CNC machining and stamping are supported by our own facilities, while casting and selected surface finishing are coordinated through audited partners. Every order is backed by final dimensional inspection, CMM verification, and FAI before shipment — so you get consistent quality, reliable lead times, and full engineering support from material selection to cost optimization.
