For an OEM specialised in sustainable energy projects, a battery enclosure design specified M12 semi hex closed end rivet nuts. The fasteners had to be closed end to prevent ingress of dust or dirt, and hexagonal for increased spin out resistance in 6mm thick parent material.
The deal was signed, but the customer needed the project to kick off much sooner than planned. Therefore the prototype enclosures had to be manufactured rapidly, long before the required customised fasteners were being produced. Dejond N.V was approached by the OEM and asked how quickly it could supply an acceptable alternative fastener.
Tubtara® approach and solution
Dejond proposed to rework stocked cylindrical parts and modify them into a hex rivet nut, suitable for the application. The company took standard hex M12 machine tooling and modified the dies and punches in its tool shop to fit into a post operation machine. This newly constructed machine set-up allowed the transformation of cylindrical into semi-hex shaped HUPX rivet nuts.
Within two weeks Dejond had manufactured and shipped a small quantity for the prototype builds, which were tested and validated. Another shipment of reworked product allowed the subcontractor to complete their first production batch. These urgent deliveries sufficed until a completely cold formed production run would become available two months later.
“Dejond’s flexibility and post operation capabilities can offer customers short-term rivet nut solutions, even if the desired part is not available from stock, by simply reworking stocked standards,” explains Dejond N.V.
