Changzhou Hongxinyutai Precision Mold Co., Ltd. has been a trusted manufacturer of high-precision injection molded components since 2017. Our PA/PPS Magnet Rotor Injection Molding with Ferrite or NdFeB magnets offers exceptional durability, shatter-proof performance, and automated robotic arm collection for efficient production. With a strict 0.02mm tolerance, these rotors meet the demanding requirements of modern motor applications. Backed by our TS16969-certified facility and experienced team, we deliver consistent quality across global markets.
Our magnet rotors are engineered using advanced injection molding techniques, combining either PA (Nylon) or PPS (Polyphenylene Sulfide) with high-performance ferrite or neodymium-iron-boron (NdFeB) magnets. The result is a robust, lightweight component that resists cracking and shattering even under high stress. The robotic arm collection system ensures precise handling and reduces cycle time, making our production both reliable and cost-effective.
Key Features & Technical Specifications
- Material Options: PA (up to 260°C continuous) or PPS (up to 280°C) for high thermal resistance and chemical stability.
- Magnet Types: Ferrite (low cost, moderate strength) or NdFeB (high magnetic energy, compact design).
- Precision Tolerance: ±0.02mm on critical dimensions, ensuring consistent performance in assembly.
- Shatter-Proof Design: Overmolded magnet encapsulation prevents cracking during handling and operation.
- Robotic Arm Collection: Automated pick-and-place for minimal human contact and higher throughput.
- TS16969 Certification: Quality management system tailored for automotive industry standards.

Benefits for Your Application: Our magnet rotors reduce assembly time by up to 30% thanks to the high dimensional consistency. The shatter-proof construction minimizes breakage during shipping and installation, lowering your scrap rate. Robotic arm collection ensures clean, organized parts ready for downstream processes. Whether you need a standard ferrite rotor for a cost-sensitive project or a high-performance NdFeB rotor for a compact motor, we offer flexible customization.
At Changzhou Hongxinyutai, we have a factory of 1,000–3,000 square meters with a team of 51–100 skilled employees. Our TS16969 certification reflects our commitment to quality in automotive and industrial sectors. We serve customers across North America, South America, Europe, Asia, and beyond, shipping from Jiangsu, Shanghai, and Shenzhen ports. Our advanced injection molding machines and robotic automation enable fast turnaround times while maintaining the 0.02mm tolerance you require.

Frequently Asked Questions
-
Q: What is the typical lead time for custom magnet rotors?
A: Lead time depends on complexity and quantity. Standard samples can be shipped within 15–20 working days after tooling approval. Production orders typically take 25–40 days. -
Q: Can I mix PA and PPS materials in the same rotor?
A: Yes, we offer multi-material injection molding. For example, a PPS core with PA overmold is possible, but we recommend discussing your specific requirements with our engineering team. -
Q: How do you ensure the 0.02mm tolerance?
A: We use precision molds machined with CNC and EDM, followed by CMM inspection. Each batch is sampled and checked for dimensional consistency. -
Q: Do you provide ferrite and NdFeB magnets in the same rotor?
A: Typically one type per rotor. However, we can design hybrid magnet configurations for special applications (e.g., variable magnetic field). -
Q: What is the maximum size of a rotor you can produce?
A: Our injection molding machines can handle parts up to 300mm in diameter. For larger sizes, please consult our sales team. -
Q: Is the shatter-proof design tested?
A: Yes, we perform impact tests (drop and vibration) to ensure the magnet remains encapsulated. Our rotors have passed automotive-level durability tests. -
Q: Do you offer certifications besides TS16969?
A: TS16969 is our primary automotive certification. We can also provide material test reports and dimensional inspection reports upon request. -
Q: Can I get a small quantity for prototyping?
A: Absolutely. We support low-volume prototype runs (e.g., 50–200 pieces) for evaluation before mass production.
