A complete Swiss-type, CNC and finishing floor across four buildings on one Long Beach block — 30,000+ square feet, more than thirty associates, purpose-built for tight-tolerance work in stainless, titanium and PEEK up to 1" diameter.
Multi-axis sliding-headstock turning for 1" diameter and below. Long, slender, high-aspect parts in one setup. This is our bread and butter.
Twin-spindle, multi-turret CNC lathes for complex prismatic-on-turned features. Complete parts off the machine, no secondary chucking.
3, 4 and 5-axis VMCs for milled bodies, manifolds and fixtures. Probing and in-process inspection for first-article discipline.
Marking and fine-feature cutting. Part traceability, logo marking, and laser-cut features on thin-wall hardware.
Progressive and single-hit stamping for sheet and strip components. Fixtured and inspected like machined work.
Formed wire components and CNC-routed plate / panel work rounding out the mechanical capability set.
Clean-room prep. Aqueous processes, cleanliness protocols that survive downstream audits.
Edge-breaking and surface conditioning tuned to the application — flow parts finished for flow.
Automated dimensional QA with vision systems. Every production part measured; every first article certified.
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.
We read every drawing as an engineer first and a shop second. If a geometry fights manufacture — or a fit can be improved at use — we'll flag it, and if you want, we'll redesign the part with you. Many of our long-running programs started as a single quote that turned into a product fix.
Engineering walks the drawing. Flags GD&T, stack-up, and manufacturability issues.
Specific, actionable notes back to your team — not generic "consolidate features" hand-waving.
Where performance is at stake (flow, seal, assembly fit), we propose changes that improve the part in use.
Red-line drawings, revised models, first-article reports — the paper trail your quality system expects.
PDF, STEP, or marked-up sketch — whatever you have. We'll come back with a quote, a delivery date, and questions if we have them.
