Where Engineering
Meets Production

I bridge the gap between design intent and manufacturing reality — ensuring every component is not only well-conceived but reliably producible at scale.

At Northvolt, I worked across production engineering, quality control, and mechanical design for battery manufacturing lines. I designed tooling and fixtures that reduced yield loss from 18% to 2%, and developed in-house test equipment that cut procurement costs by 50%.

Proficient in Siemens NX, CREO, SolidWorks, and Ansys, I bring a systematic, data-driven approach to every design challenge — from concept through to production-ready output.

01
Hi-pot Master Block
In-house precision test fixture — Siemens NX

Designed and developed an in-house Hi-pot Master Block to replace externally procured test equipment. Designed in Siemens NX, prototyped via 3D printing, then sent for precision machining.

The design integrates a copper contact plate with precision-spaced fingers, a housing block for the resistor array (4MΩ, 4W at 4kV/1mA), and an internal cable management system.

Impact50% reduction in procurement costs. Full design-to-machining cycle completed within 6 weeks.

02
Hi-pot Side Blocks
Precision side-flange protection blocks — Siemens NX

Designed left and right hi-pot side blocks with precision grooves to protect battery cell side flanges from deformation during hi-pot testing, along with a custom fixture to locate and secure both blocks.

Full design-to-production cycle completed in under 2 weeks — from initial CAD, custom screw design, 3D print verification, to workshop machining submission.

ImpactEliminated side-flange deformation during testing. All 4 components designed and submitted for production.

Thickness Transfer Shuttle Head
Gripper head redesign to prevent glue detachment — Siemens NX

Identified and resolved a critical production issue where glue accumulation on the thickness measurement shuttle caused cell flanges to detach. Delivered a redesigned gripper head featuring a meshed rubber-faced contact surface.

The new head replaced a solid slot prone to glue trapping with a perforated rubber pad that stays clean under contamination. Prototyped and verified via 3D printing before production alignment.

ImpactPrevented flange detachment defects. Improved line uptime and quality consistency.

Yield Loss Reduction Fixture
Battery cell positioning fixture — Siemens NX · Cell Assembly

Engineered a mechanical fixture for the battery cell assembly line to minimise operator-induced stress on prismatic cells during production. Root cause analysis identified inconsistent cell handling as the primary driver of 18% rework yield loss.

The aluminium fixture constrains cells within precise tolerances, removing variability in positioning and contact force. Designed in Siemens NX, validated through iterative prototyping, and implemented on the production line at Northvolt Ett.

ImpactYield loss reduced from 18% to 2% — a 16 percentage-point improvement directly improving output and reducing rework cost.
