What we run.
What we run it on.

Ultrasonic cleaning

Clean-room prep. Aqueous processes, cleanliness protocols that survive downstream audits.

Deburring + tumbling

Edge-breaking and surface conditioning tuned to the application — flow parts finished for flow.

Vision inspection

Automated dimensional QA with vision systems. Every production part measured; every first article certified.

Assembly + kitting

Sub-assemblies, matched sets, kitted deliverables — we ship parts ready for your next operation, not just bagged and tagged.

We run multiple 3D printing systems on the floor — both resin and filament — in build envelopes up to 900 × 900 × 900 mm.

Printing in-house means fixtures, soft jaws, inspection aids and form-and-fit prototypes are made the same week they are needed, without waiting on an outside vendor or a tooling quote. A part can be printed, checked against the drawing, revised and printed again before the machining setup is built.

At Stello, quality is an active, continuously managed process—not simply a manual on a shelf.

Our QMS Copilot helps us organize quality requirements, maintain calibration and recurring obligations, manage SCAR and corrective-action workflows, connect customer-specific requirements to objective evidence, and monitor improvement over time. Developed from our own real-world manufacturing experience, it gives our team greater visibility into the controls, actions, and records that support consistent production and dependable customer service.

QMS Copilot supports our qualified personnel and established quality procedures; it does not replace their judgment or independent certification.

Built on the continuous-improvement disciplines proven in world-class industrial manufacturing — lean, kaizen, and plan-do-check-act — applied to the documentation and compliance burden of running multiple quality specifications at once.
