Case Study: Harwin achieves precision micro-mould production and major productivity gains with Vero Software's VISI suite

Harwin - Customer Case Study

Harwin Plc, a manufacturer of high-reliability Gecko micro-connectors used in aerospace, motorsport, defence and other demanding sectors, faced the challenge of producing multi-impression moulds containing hundreds of tiny, hard-to-machine features (some with 0.2 mm wall thickness). Conventional cutters couldn’t reach these fine details, and complex parts and multiple variations in a single cassette required extensive electrode and wire-EDM work to achieve consistent, defect-free mould cavities.

Harwin adopted the VISI suite (VISI Mould, Electrode, PEPS‑Wire, Machining 2D/3D, Progress and Viewer) integrated with ProEngineer to handle tooling, electrode design, CAM and press-tool development. The workflow enabled real-time tooling adjustments, automated shrinkage and split-line generation, offline programming for die-sinkers, wire EDMs and mills, and collision-checked electrode production—allowing multiple electrodes to be machined simultaneously, maximizing cavity count per cassette and delivering higher-quality finishes, fewer errors and a substantial uplift in productivity.
