We would like to introduce the "Hairpin-Type Stator Manufacturing Line" produced by Gehring in Germany. This presentation will showcase a series of manufacturing technologies used in the production line for stator components for EVs, along with a sample display of the finished hairpin-type stators. In a collaborative video with WAFIOS, you can see a series of manufacturing processes including pin production, assembly, pin expansion and bending, welding, impregnation, and powder coating. Additionally, samples of honing tools and laser roughening will also be displayed at the same booth. Gehring and WAFIOS have been in a cooperative relationship since April 2021, aiming to provide a turnkey solution for hairpin-type stator manufacturing lines. This exhibition will be presented as a joint display by our company, the agent for Gehring, and CORRENS, the agent for WAFIOS. Exhibition Dates: January 22 (Wednesday) to January 24 (Friday), 2025 Venue: Tokyo Big Sight, East Hall E41-12 Exhibiting Manufacturers: Gehring, WAFIOS (Collaboration exhibition by CKB and CORRENS) Opening Hours: 10:00 AM to 5:00 PM

Hairpin-type stator manufacturing line for electric vehicles (EV)
Gearing Co. proposes a production line for stator manufacturing, from the production of pins for EV stator components to the powder coating process.

- Pin Production and Assembly Process The production of pins involves wire rewinding correction, coating removal, cutting, hairpin bending, and transportation using WAFIOS equipment. In the subsequent assembly process, insulation paper and pin windings are inserted and assembled into the stator core. The insertion/assembly method can be adjusted according to customer requirements. - Pin Expansion and Bending Process The expansion process and the subsequent bending process can be performed using a single piece of equipment. - Welding Process To achieve excellent welding, we focus on positioning and clamping techniques. Additionally, we can add specifications for pin cutting before welding to eliminate height discrepancies. - Impregnation Process This includes preheating, spraying, gelation, and curing in an oven. Uniform temperature supply through induction heating allows for homogeneous impregnation. - Powder Coating The welding parts of the pins are coated for insulation.
