One-Stop Custom PPS Motor Bobbin Mold: Design (UG/Parasolid) & Manufacturing, IATF 16949:2016NegotiableMOQ: 5000 Pieces
Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, is a professional manufacturer specializing in precision injection molds with a factory area of 1,000–3,000 square meters and a dedicated team of 51–100 employees. Our Custom PPS Plastic Injection Mold for Brushless Motor Insulation Bobbin is engineered to meet the demanding requirements of the automotive and motor industries. Designed with 2+2 cavities for balanced production efficiency, this mold is manufactured in full compliance with IATF 16949:2016 quality management standards, ensuring consistent performance and long-term reliability.
This mold is tailored for manufacturing high-precision insulation bobbins used in brushless motors. The use of PPS (Polyphenylene Sulfide) resin offers exceptional thermal resistance, electrical insulation, and dimensional stability — critical properties for motor components operating under high temperatures and continuous vibration. With our advanced mold design and precise machining capabilities, we deliver a solution that maximizes uptime and minimizes scrap rates for your production line.

Detailed Product Advantages
- PPS Material Compatibility: Our mold is specifically designed to handle the high temperature and flow characteristics of PPS, ensuring complete cavity fill and minimal warpage.
- Precision & Repeatability: With tolerances as tight as ±0.01mm, every bobbin produced meets strict dimensional requirements for seamless assembly in brushless motors.
- 2+2 Cavity Design: This configuration allows simultaneous production of two identical bobbins plus two cores or inserts, boosting output without sacrificing quality.
- IATF 16949:2016 Compliance: Our entire manufacturing process follows the automotive industry's stringent quality system, from design review to mold trial and final inspection.
- Enhanced Durability: Hardened steel inserts and optimized cooling extend mold life, reducing long-term replacement costs.
- Customization Available: We tailor gate design, cooling layout, ejection mechanism, and surface finish to match your specific injection molding machine and production requirements.
Benefits to Your Business
- Faster Production Cycles: Efficient cooling and balanced runner system minimize cycle time, increasing your overall output.
- Lower Scrap Rate: High precision mold reduces flash and short shots, saving material costs.
- Consistent Quality: Each bobbin maintains uniform electrical insulation properties, critical for motor reliability.
- Global Support: We ship from Jiangsu, Shanghai, and Shenzhen ports, serving markets across North America, Europe, Asia, and more.
