Changzhou Hongxinyutai Precision Mold Co., Ltd. has been a trusted manufacturer of precision injection molding solutions since 2017. With a factory spanning 1,000-3,000 square meters and a team of 51-100 skilled professionals, we specialize in producing OEM custom plastic injection molding for motor parts. Our service includes a 1-year warranty, free sample, dedicated technical support, and rapid prototyping—all designed to help you bring your motor components to market faster and with confidence. Whether you need complex housings, precision gears, or durable connectors, our advanced manufacturing capabilities ensure consistent quality and performance.
Our commitment to excellence is backed by TS16969 certification, reflecting our adherence to strict quality management standards in the automotive and industrial sectors. We serve a global clientele across North America, South America, Europe, Asia, and beyond, offering reliable shipping from Jiangsu, Shanghai, and Shenzhen ports. Below, we detail the key features and benefits of our custom injection molding service for motor parts.
Key Features & Technical Specifications
Precision Engineering: Achieve tight tolerances of ±0.01mm for critical motor components such as gear housings, bearing retainers, and fan blades. Our advanced CNC machining and mold design ensure repeatable accuracy.
Material Versatility: We work with a wide range of engineering plastics, including Nylon (PA6, PA66), Polyacetal (POM), Polycarbonate (PC), ABS, and high-temperature resistant materials. Each material is selected based on your motor part's mechanical, thermal, and electrical requirements.
Rapid Prototyping: From concept to prototype in as little as 7-10 days. Our rapid prototyping service uses 3D printing or quick-turn mold tooling to help you validate design and functionality before mass production.
Free Sample & 1-Year Warranty: We provide a free sample for your evaluation, and all production parts are covered by a 1-year warranty against defects, ensuring peace of mind.
Technical Support: Our experienced engineers offer end-to-end support, from DFM (Design for Manufacturing) analysis to mold flow simulation and production optimization.
Customization Options: Choose from a variety of surface finishes (textured, gloss, matte), colors (Pantone/RAL), and secondary operations (insert molding, ultrasonic welding, assembly).
| Parameter | Specification |
|---|---|
| Mold Cavity | Single / Multi-cavity (up to 32 cavities) |
| Injection Pressure | Up to 2500 bar |
| Clamping Force | 80 – 500 tons |
| Production Capacity | 1,000,000+ parts per month |
| Quality Inspection | CMM, projector, hardness tester, and in-process SPC |
Our injection molding process is optimized for motor parts that require high dimensional stability, heat resistance, and electrical insulation properties. Common applications include:
Motor housings – for DC, AC, stepper, and servo motors
Gears and pulleys – low noise, wear-resistant plastic gears
Brackets and mounts – structural support with vibration dampening
Connectors and terminals – precise pin alignment for reliable electrical connections
Fan blades and impellers – aerodynamic design for efficient cooling
Insulators and brush holders – high dielectric strength materials
By choosing Changzhou Hongxinyutai, you benefit from cost-effective tooling solutions with a typical mold life exceeding 500,000 shots, ensuring long-term production stability. Our rapid prototyping service reduces your development cycle, while the free sample allows you to test fit, function, and material compatibility before committing to volume orders.

Frequently Asked Questions
Q: What is the typical lead time for a custom injection mold for motor parts?
A: Our standard lead time for a new mold is 20-30 days, depending on complexity. For simple parts, we can deliver a rapid prototype mold in 7-10 days. Rush services are available on request.Q: Do you provide free samples? How can I get one?
A: Yes, we offer free samples for evaluation. Simply send us your 3D drawing or specifications, and we can produce a sample using our rapid prototyping service. Shipping costs may apply.Q: What materials do you recommend for motor parts that are subject to high heat?
A: For high-temperature applications, we recommend materials such as PEEK, PPS, or glass-filled Nylon (PA66+GF30). Our engineering team can help you select the best material based on your operating temperature, mechanical load, and chemical exposure.Q: Is the 1-year warranty applicable to all parts?
A: The 1-year warranty covers defects in material and workmanship for all production parts. It does not cover damage from improper use, modification, or normal wear. Please refer to our warranty terms for details.Q: Can you handle complex geometries with undercuts or internal threads?
A: Absolutely. Our mold design team is experienced in creating complex molds with sliders, lifters, and unscrewing mechanisms. We can produce parts with intricate internal and external features.Q: What quality certifications do you hold?
A: We are certified under TS16969, which is a quality management system standard for the automotive industry. This ensures that our processes meet rigorous quality and consistency requirements.Q: Do you offer assembly or secondary operations?
A: Yes, we offer various secondary operations including ultrasonic welding, hot stamping, overmolding, pad printing, and sub-assembly. Please specify your requirements when requesting a quote.Q: How do you ensure the dimensional accuracy of motor parts?
A: We use a combination of in-process inspection using CMM (Coordinate Measuring Machine) and final inspection with projectors and gauges. Statistical Process Control (SPC) is implemented to monitor and maintain tight tolerances throughout production.
