Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for high-performance Precision PA/PPS NdFeB Magnet Rotor Injection Molds. As a dedicated factory established in 2017, we specialize in engineering molds that meet the rigorous demands of mass production supply chains, particularly for markets in Southeast Asia, North America, and Europe. Our molds are designed to produce magnet rotors using advanced materials like PA (Nylon), PPS, and NdFeB magnetic powder, ensuring exceptional magnetic performance and mechanical strength. With a factory spanning 1,000–3,000 square meters and a skilled team of 51–100 employees, we deliver precision, reliability, and cost-efficiency for B2B clients seeking long-term partnerships.
Our injection molds are engineered to achieve tight tolerances and consistent part quality across millions of cycles. Whether you need single-cavity or multi-cavity configurations, we offer customized solutions to match your production volume and part complexity. The mold steel is carefully selected (e.g., P20, H13, 718H) to withstand high-temperature injection processes and abrasive NdFeB compounds, extending mold life and reducing per-part cost. Below, we detail the key features and technical specifications that make our mold a top choice for Southeast Asian B2B mass production.
Key Features & Technical Specifications
| Parameter | Specification |
|---|---|
| Mold Base Material | Standard: P20 / Optional: H13, 718H, S136 |
| Cavity Configuration | 1, 2, 4, or 8 cavities (customizable) |
| Mold Life Expectancy | 500,000 – 1,000,000 cycles (with proper maintenance) |
| Part Tolerance | ±0.02 mm on critical dimensions |
| Injection Material | PA6, PA66, PPS, NdFeB magnetic compound |
| Maximum Part Weight | Up to 200 grams (depending on design) |
| Cooling System | Conformal cooling channels for uniform temperature |
| Surface Finish | SPI A2 – A3 (standard) / Mirror polish available |
Advanced Design for Injection Molding: Our mold incorporates a carefully engineered gating system (hot runner or cold runner) to ensure uniform filling of the magnet rotor cavity, reducing internal stress and warpage. The ejection system is designed with multiple pins and sleeves to safely eject the delicate rotor without deformation. For NdFeB magnet compounds, we use wear-resistant tool steel inserts to protect against abrasive particles, extending mold life significantly.
Benefits for Your Mass Production:
- High Cycle Consistency – Our molds are built to maintain tight tolerances over hundreds of thousands of cycles, minimizing scrap and downtime.
- Fast Turnaround – With integrated cooling channels, cycle times can be reduced by up to 15% compared to standard designs.
- Customizable to Your Need – We adapt the mold design to your specific injection molding machine (e.g., tonnage, tie-bar spacing) and rotor geometry.
- Cost-Effective for High Volumes – Multi-cavity molds (up to 8 cavities) maximize output per press, lowering unit cost.
- Material Compatibility – Optimized for PA, PPS, and NdFeB compounds, including difficult-to-mold glass-filled grades.
Quality Assurance – Our factory is TS16969 certified (equivalent to IATF 16949), ensuring rigorous quality management throughout design, machining, assembly, and trial runs. Each mold undergoes comprehensive testing, including dimensional inspection (CMM), hardness test, and pilot injection trials. We provide detailed documentation such as mold book, maintenance guidelines, and spare parts list.

Frequently Asked Questions (FAQ)
1. What materials can be used with this mold?
This mold is designed for PA (Nylon 6, Nylon 66), PPS, and NdFeB magnetic compounds. We can also adapt for other engineering plastics upon request.
2. What is the typical mold life for PA/PPS magnet rotor production?
Under normal maintenance, the mold life ranges from 500,000 to 1,000,000 cycles. For highly abrasive NdFeB compounds, we recommend using wear-resistant inserts to achieve maximum life.
3. Can you produce multi-cavity molds for high-volume production?
Yes, we offer 1, 2, 4, 6, and 8-cavity configurations. The optimal number depends on your injection machine tonnage and part size.
4. What is the lead time for a custom magnet rotor mold?
Standard lead time is 4–6 weeks from final design approval. Faster delivery may be available for simpler designs.
5. Do you provide trial shots before shipping?
Absolutely. We perform trial injection at our facility and send you sample parts for approval. We can also adjust the mold based on trial results.
6. What certifications do you hold?
Our factory is TS16969 certified, which aligns with IATF 16949 quality management standards for automotive and precision manufacturing.
7. How do you ensure the mold fits my injection molding machine?
We require your machine specifications (platen size, tie-bar spacing, nozzle type, etc.) and design the mold base and clamping system accordingly.
8. What kind of after-sales support do you offer?
We provide a one-year warranty against manufacturing defects, free technical support, and a spare parts set (e.g., extra ejector pins, springs). We can also assist with minor modifications if your rotor design evolves.
Contact us today to discuss your magnet rotor injection mold requirements. With our engineering expertise, TS16969 certification, and strong track record in Southeast Asian B2B supply chains, we are ready to deliver the precision and reliability you need for mass production.
