Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd., a professional manufacturer established in 2017 with a factory size of 1,000–3,000 square meters and a dedicated team of 51–100 employees. We specialize in precision injection molding and mold making, with a strong focus on high-performance engineering plastics. Our Robotic Arm Collection & Mold Protection PPS+GF40 Motor Bobbin Injection Molding OEM service is designed to deliver reliable, durable, and precisely engineered components for automated systems and mold protection applications. Leveraging our TS16969-certified quality management system, we ensure every part meets the rigorous demands of the automotive and industrial sectors.
Our PPS+GF40 (Polyphenylene Sulfide reinforced with 40% glass fiber) motor bobbin is an essential component for robotic arm collection systems and mold protection mechanisms. This material offers exceptional thermal stability, chemical resistance, and mechanical strength, making it ideal for harsh environments where continuous operation and precision are critical. We offer full OEM customization, from mold design to final production, ensuring that your specific dimensions, tolerances, and performance requirements are met.
Product Features & Technical Advantages
- High-Performance Material: PPS+GF40 combines excellent heat resistance (continuous use up to 220°C), outstanding chemical resistance against solvents and oils, and high dimensional stability. This ensures long service life in robotic arm motors and mold protection systems.
- Precision Injection Molding: Our advanced injection molding machines, combined with tight process control, deliver parts with tolerances as low as ±0.05 mm. This guarantees consistent fit and function for your bobbin assemblies.
- Robust Design for Automation: The bobbin is engineered to withstand the mechanical stresses of robotic arm movements, including repeated acceleration, deceleration, and vibration. Its design also facilitates easy integration with automated collection systems.
- Mold Protection Features: The bobbin can be designed with integrated features such as anti-rotation slots, snap-fit geometries, or reinforced ribs to enhance the protection of the mold and the motor assembly.
- Customizable Colors & Configurations: We offer a wide range of colors (e.g., black, natural, custom RAL) and can modify the design to include additional mounting holes, terminal pins, or wire guides as per your drawings.
- 100% Quality Inspection: Every batch undergoes dimensional inspection, material verification, and functional testing (e.g., dielectric strength, pull-out force) to ensure compliance with your specifications.
Technical Specifications (Typical Values for PPS+GF40 Bobbin)
| Parameter | Value | Remarks |
|---|---|---|
| Tensile Strength | ≥ 150 MPa | ISO 527 |
| Flexural Modulus | ≥ 12,000 MPa | ISO 178 |
| Heat Deflection Temperature (1.8 MPa) | ≥ 260°C | ISO 75 |
| Dielectric Strength | ≥ 20 kV/mm | IEC 60243 |
| Flammability Rating | V-0 (0.8 mm) | UL 94 |
| Mold Shrinkage | 0.2 – 0.4% | Along flow direction |
These specifications are typical for PPS+GF40 injection molded parts. Actual values may vary based on the specific bobbin design and molding conditions. We can adjust parameters to meet your specific requirements.
OEM Customization & Quality Assurance
As an OEM partner, we provide end-to-end support from concept to mass production. Our team of engineers works closely with you to optimize the bobbin design for manufacturability, cost efficiency, and performance. We use advanced mold flow analysis software to predict filling, cooling, and warpage, ensuring first-time-right mold development.
- Mold Design & Fabrication: In-house mold shop with 5-axis CNC, EDM, and wire cutting capabilities. We create multi-cavity molds with hot runner systems for high-volume production.
- Process Control: All injection molding parameters (temperature, pressure, speed, cooling time) are monitored and recorded in real-time. Statistical process control (SPC) is implemented for critical dimensions.
- Material Traceability: We source PPS+GF40 from qualified suppliers and maintain batch traceability throughout production.
- Testing & Verification: In addition to dimensional checks, we conduct functional tests such as bobbin winding force, solderability, and thermal cycling to ensure reliability.

Frequently Asked Questions (FAQ)
1. What is PPS+GF40 and why is it used for motor bobbins?
PPS+GF40 is a polyphenylene sulfide reinforced with 40% glass fiber. It offers excellent thermal stability (up to 220°C continuous), high mechanical strength, good chemical resistance, and low moisture absorption. These properties make it ideal for motor bobbins in robotic arms and mold protection systems where reliability under harsh conditions is critical.
2. Can you produce bobbins with custom dimensions and tolerances?
Yes, we specialize in OEM custom parts. We can produce bobbins according to your 2D/3D drawings with tight tolerances (e.g., ±0.05 mm). We also offer design optimization suggestions to improve manufacturability and reduce costs.
3. What is the typical lead time for samples and mass production?
Sample lead time is usually 15–25 working days after mold completion. For mass production, typical lead time is 30–45 days, depending on order quantity and complexity. We can expedite for urgent orders upon request.
4. Do you have any quality certifications?
Yes, we are certified under TS16969 (equivalent to IATF 16949), which is a stringent quality management system standard for the automotive industry. This ensures consistent quality and process control.
5. What is the minimum order quantity (MOQ) for this product?
MOQ for custom injection molded parts is typically 500–1,000 pieces per design. However, for initial prototypes or small-batch trials, we can accommodate lower quantities. Please contact us with your specific requirements.
6. How do you ensure the bobbin's performance in robotic arm applications?
We conduct functional testing such as dielectric strength, pull-out force of terminal pins, and thermal cycling. Additionally, we can perform custom tests based on your application needs, such as vibration resistance or endurance testing.
7. Can you provide material certifications and test reports?
Yes, we provide material certificates of compliance (COC) from our resin suppliers, as well as dimensional inspection reports and functional test reports for each batch upon request.
8. Do you offer mold design and manufacturing services for this product?
Absolutely. We have an in-house mold shop with experienced engineers. We can design and manufacture the injection mold specifically for your bobbin, including multi-cavity, hot runner, and side action mechanisms. Mold life is typically 500,000 to 1,000,000 shots.
