Changzhou Hongxinyutai Precision Mold Co., Ltd. is a dedicated manufacturer of high-performance injection mold tooling for industrial applications. Since 2017, we have focused on delivering precision mold solutions for complex engineering plastics and magnetic material integration. Our Industrial PA/PPS Magnetic Rotor Injection Mold Tooling is specifically engineered to support high-volume production of NdFeB magnetic rotors, meeting the demanding requirements of Southeast Asian markets. With a hardened steel core, this tooling ensures exceptional durability, dimensional stability, and repeatability for large-scale manufacturing.
This mold is designed to handle the unique challenges of overmolding PA (polyamide) or PPS (polyphenylene sulfide) onto NdFeB magnets. The robust construction minimizes wear, reduces downtime, and extends tool life, making it a cost-effective investment for manufacturers in the automotive, electronics, and renewable energy sectors. Our factory, spanning 1,000–3,000 square meters, houses advanced CNC machining centers, EDM equipment, and CMM inspection tools to guarantee micron-level precision.
Below are the key technical parameters and features of this mold tooling:
| Parameter | Specification |
|---|---|
| Mold Base Material | P20 / 1.2311 hardened to HRC 32-36 |
| Core / Cavity Steel | H13 (1.2344) or SKD61, hardened to HRC 48-52 |
| Injection Material | PA6, PA66, PA6T, PPS, PPS+GF |
| Magnet Type | Sintered NdFeB (grade N35-N52, etc.) |
| Cavity Count | 2, 4, 6, 8, or customized |
| Hot Runner System | Available (optional) |
| Cooling System | Conformal cooling channels for uniform temperature |
| Mold Life Expectancy | ≥ 1,000,000 cycles (with proper maintenance) |
Key Features & Benefits
- Hardened steel core – Resists abrasion from NdFeB magnet particles and high injection pressures, ensuring long-term dimensional accuracy.
- PA/PPS optimized design – Accommodates the high melt temperatures (up to 320°C for PPS) and flow characteristics of engineering plastics without warpage.
- High-volume production – Multi-cavity layouts and efficient cooling reduce cycle times by 15–20% compared to standard molds.
- Precision magnet insertion – Custom-designed inserts and positioning features guarantee exact alignment of NdFeB magnets during overmolding.
- Easy maintenance – Modular construction allows quick replacement of wear components, minimizing downtime.
- Wide material compatibility – Suitable for both PA and PPS compounds, including glass-filled and flame-retardant grades.
- Compliance with TS16969 – Manufactured under a quality system that meets automotive-grade standards, ensuring traceability and consistency.
The mold tooling has been rigorously tested in our facility and deployed in high-volume production lines across Southeast Asia. Customers report improved yield rates (above 98%) and reduced scrap due to the stability of the hardened steel core. The conformal cooling channels eliminate hot spots, resulting in uniform shrinkage and better magnetic performance of the final rotor.

Frequently Asked Questions
Q1: What is the lead time for this mold?
Lead time typically ranges from 30 to 45 working days, depending on cavity count and complexity. Rush orders can be discussed.
Q2: Can you customize the mold for a specific magnet shape?
Yes, we design and manufacture molds based on your magnet dimensions, rotor geometry, and material specifications. Provide a 3D model or drawing for a quote.
Q3: Is the mold suitable for both PA and PPS materials without modification?
Our mold core and cavity are designed to withstand high temperatures; however, we recommend confirming the material type and temperature requirements. We can adjust the cooling system and gate design accordingly.
Q4: What is the expected mold life for high-volume production?
With proper maintenance and using hardened steel (H13/SKD61), the mold can produce over 1,000,000 cycles. Regular cleaning and re-polishing may extend life further.
Q5: Do you offer trial runs before mass production?
Yes, we can perform sample molding at our facility. You can send your magnets and plastic material for a trial run to verify fit and quality.
Q6: What certifications does your company hold?
We hold TS16969 certification, which covers our quality management system. Additional certifications can be supported upon customer request.
Q7: How do you ensure the mold is compatible with my injection molding machine?
We require your machine specifications (tie-bar distance, platen size, injection unit, etc.) and design the mold accordingly. We also provide a mold base drawing for approval.
Q8: What is your shipping and packaging process?
Molds are packed in wooden crates with anti-rust oil, vacuum-sealed plastic, and shock-absorbing materials. We ship via sea freight from Jiangsu, Shanghai, or Shenzhen ports.
