Execution required controlling tight fin features, achieving the expected surface finish, and managing supplier responsiveness during the build.
Achieving 6mm pitch and 4.5mm fin thickness (±0.2mm) consistently was the primary build challenge.
Defined and finalized a bead-blasting finish route to meet appearance expectations and ensure consistent output across samples.
✔ Confirmed envelope size and fin criticals – 103×145×45mm, 6mm pitch, 4.5mm thickness (±0.2mm)
✔ Aligned material to requirement – Aluminium 6061-T6
✔ Defined finish expectation and acceptance reference at the start
✔ Converted requirements into extrusion-feasible geometry and build plan
✔ Coordinated die development approach and sample run strategy
✔ Locked checkpoints for fin geometry verification before finishing
✔ Produced 10 sample parts with controlled fin geometry targets
✔ Addressed execution risks – fin thickness, fin pitch, and surface quality
✔ Verified dimensions and tolerance achievement through inspection checks
✔ Delivered samples for customer evaluation and application validation
✔ Standardized surface finish using Glass Bead Blasting for repeatable output
✔ Provided build learnings and documentation to support future mass production readiness
We followed a structured execution process to lock dimensions, standardize surface finish, and establish a repeatable baseline for future mass production.
