Automotive relay coil winding
An automotive relay is a key electromagnetic switching component widely fitted on vehicles. It takes charge of switching circuits for headlights, cooling fans, fuel pumps and many‑on‑board electrical systems. Even minor defects inside the relay coil may lead to unstable circuit performance or component failure, which makes consistent winding quality extremely important.
As the core part of an automotive relay, the coil requires highly uniform winding tension and neat layer arrangement during production. Many auto‑parts manufacturers are facing challenges when scaling‑up relay coil output: traditional single‑station winding equipment limits productivity, while inconsistent manual feeding often causes defective coils.
Based on years‑long practical experience in automotive‑coil automation, SIPU designed this multi‑spindle winding machine specifically for automotive relay coil batch production. Running with servo closed‑loop tension control, the machine keeps steady wire tension throughout the winding cycle, avoiding loose windings, enamel damage and uneven coil layers. Its multi‑head parallel‑working layout allows dozens of coils to be wound in one cycle, greatly raising daily production capacity.
