Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for precision injection molded components. We specialize in producing high-performance OEM PPS+GF40 Motor Bobbin parts, fully certified under IATF 16949:2016. Our factory, established in 2017, spans 1,000–3,000 square meters and is equipped with advanced injection molding machines and a dedicated team of 51–100 skilled professionals. With years of experience serving global markets including North America, Europe, and Southeast Asia, we deliver bobbin solutions that meet the demanding requirements of automotive and industrial motor applications.
Our PPS+GF40 motor bobbin combines the inherent thermal stability of Polyphenylene Sulfide (PPS) with 40% glass fiber reinforcement, resulting in a product that offers exceptional mechanical strength, dimensional stability, and resistance to high temperatures and chemicals. This bobbin is specifically designed for use in electric motors, transformers, solenoids, and other electromagnetic components where reliability under harsh conditions is critical.
Key Features & Technical Specifications
- Material: PPS (Polyphenylene Sulfide) + 40% Glass Fiber – provides excellent creep resistance, low moisture absorption, and high stiffness.
- Thermal Performance: Continuous operating temperature up to 240°C; short-term peaks up to 260°C.
- Electrical Insulation: High dielectric strength and volume resistivity, making it ideal for coil winding applications.
- Flame Retardance: UL94 V-0 rating available (optional, upon request).
- Chemical Resistance: Resistant to most solvents, oils, and fuels, ensuring long-term durability in automotive environments.
- Dimensional Accuracy: Tight tolerances achievable (typical ±0.02 mm) through precision mold design and process control.
- IATF 16949:2016 Certified: Our quality management system meets the stringent automotive standard, ensuring consistent product quality and traceability.
- OEM Customizable: We can produce bobbins with custom dimensions, wall thickness, pin configurations, and colors to match your specific design.
- Surface Finish: Smooth, ejection-friendly finish with no burrs or flash; optional secondary operations (e.g., ultrasonic welding, insert molding).
Typical Applications
- Electric motor stators and rotors
- Automotive solenoid coils
- Transformer bobbins for power supplies
- Relay and contactor coil formers
