As a professional manufacturer of precision injection parts, Changzhou Hongxinyutai Precision Mold Co., Ltd. (established in 2017, factory size 1,000–3,000 m², 51–100 employees) proudly introduces our Wholesale OEM Automotive PA/PPS Magnet Rotor. With a strict tolerance of ±0.02mm and heat resistance up to 150°C, these injection-molded rotors are engineered to meet the demanding requirements of automotive applications, especially for Southeast Asian markets. Our TS16969-certified facility ensures consistent quality and reliable performance for every order.
Product Highlights:
- Ultra-High Precision: ±0.02mm dimensional accuracy ensures perfect fit and stable magnetic circuit performance.
- Excellent Heat Resistance: PA/PPS materials withstand continuous operating temperatures up to 150°C, suitable for engine compartments and harsh environments.
- Material Options: Available in PA (Polyamide) for cost-effective solutions and PPS (Polyphenylene Sulfide) for superior chemical and thermal resistance.
- Injection Molded Integrity: One-piece molding eliminates weak points, reduces assembly time, and enhances rotor durability.
- OEM/ODM Capability: Customized designs, magnet insert configurations, and dimensions are fully supported.
- TS16969 Certified: Our quality management system follows automotive industry standards to ensure traceability and consistency.
- B2B Focus: Tailored for wholesale distributors, automotive parts suppliers, and OEM customers in Southeast Asia and beyond.

Detailed Benefits for Your Business:
- Reduce assembly failures: Our ±0.02mm precision ensures magnets are perfectly aligned, minimizing vibration and noise in motor assemblies.
- Withstand extreme conditions: The 150°C heat resistance is ideal for under-hood applications, oil pumps, and electric power steering systems.
- Cost-effective material choice: PA offers excellent mechanical properties at a lower cost; PPS provides superior chemical resistance for aggressive environments.
- Scalable production: Our 1,000–3,000 m² factory with 51–100 skilled workers can handle large-volume orders (thousands to millions of pieces) while maintaining tight tolerances.
- Customized solutions: We can adjust the rotor geometry, magnet pocket design, and even integrate overmolded metal inserts as per your engineering drawings.
- Fast sample development: Typically 7–10 days for prototype molds, enabling quick validation before mass production.

Our TS16969 certification (automotive quality management system) reflects our commitment to zero-defect manufacturing. Each rotor undergoes 100% dimensional inspection and functional testing before shipment. We have successfully delivered millions of injection-molded parts to leading automotive Tier 1 and Tier 2 suppliers. With flexible shipping options from Jiangsu, Shanghai, and Shenzhen ports, we ensure timely delivery to Southeast Asian markets. Choose our PA/PPS magnet rotor for a reliable, high-performance component that enhances your final product’s quality and reduces warranty risks.
Frequently Asked Questions (FAQ):
Q1: What is the minimum order quantity (MOQ) for this rotor?
A: Our standard MOQ is 1,000 pieces for new designs. However, for standard sizes or repeat orders, we can accommodate smaller quantities. Please contact us for specific requirements.
Q2: Can you provide samples for testing before mass production?
A: Yes, we offer sample parts (typically 5–10 pieces) for evaluation. Sample costs are negotiable, and we can deduct the cost from the first production order.
Q3: How do you ensure the ±0.02mm precision is maintained across large batches?
A: We use high-precision mold cavity inserts (EDM and wire-cut) and in-process statistical process control (SPC). Every critical dimension is measured with CMM (Coordinate Measuring Machine) and documented.
Q4: What is the typical lead time for a custom mold and production?
A: Mold fabrication takes about 20–30 days, and first article samples are ready within 7–10 days after mold completion. Mass production lead time is 15–25 working days.
Q5: Do you have experience with magnet insert overmolding?
A: Absolutely. We have extensive experience overmolding ferrite and NdFeB magnets. We can design the rotor to prevent magnet chipping or migration during the injection process.
Q6: Can you use PPS material with high glass fiber content (e.g., 40% GF) for better stiffness?
A: Yes, PPS with 30%–40% glass fiber reinforcement is available. This enhances dimensional stability at high temperatures. Please specify your material grade and fiber content requirement.
Q7: How do you handle quality control for export orders?
A: We provide a full inspection report with each shipment, including dimensional data, material certificates, and functional test results. Third-party inspection is also welcome.
Q8: What payment terms do you accept for B2B orders?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and occasionally PayPal for small orders. Payment terms can be negotiated for long-term partnerships.
