Case Details
Customer Demand: A domestic electrical R&D enterprise was developing a new high-efficiency motor, needing to quickly verify the structural rationality of the motor coil skeleton. The demand specified SLS nylon material (to ensure excellent electrical insulation, corrosion resistance and dimensional stability), a single batch of 10 pieces for R&D structure fit verification, and urgent delivery within 2 days. The core goal was to confirm whether the skeleton’s size, slot structure and installation position match the motor coil and stator, avoid design errors before mold opening, and control the R&D verification cost.
Solution: JITMFG responded quickly to the customer’s urgent R&D needs, adopted SLS 3D printing technology, and selected high-performance SLS nylon material that meets the electrical industry’s insulation and mechanical performance standards. Taking advantage of SLS’s support-free integrated molding feature, we realized one-step forming of the motor coil skeleton’s complex slot structure and installation holes, avoiding assembly deviations caused by split processing. We optimized the printing parameters to strictly control dimensional tolerance within ±0.2mm, ensuring each skeleton’s consistency and fit with the motor coil. The entire process was efficiently promoted: design file review and parameter debugging were completed within 3 hours, printing was finished within 13 hours, and post-processing (de-powdering, precision testing) was completed within 4 hours, finally delivering 10 pieces of qualified motor coil skeletons within 2 days as required.
Cooperation Value: Compared to traditional CNC machining (which takes 7 days for 10 pieces), the SLS process shortened the R&D verification cycle by 71% (completed in 2 days) and reduced R&D verification costs by 35% . The SLS nylon motor coil skeletons had stable dimensional accuracy and excellent insulation performance, perfectly matching the customer’s motor coil and stator installation requirements, helping the R&D department quickly verify the structural design, identify and modify 2 potential installation defects in advance, and shorten the new motor’s R&D iteration cycle by 20%.
