Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner in precision injection molding for the new energy vehicle (NEV) industry. As a dedicated manufacturer established in 2017, we specialize in producing custom NEV assembly parts using advanced injection molding techniques and creep-resistant engineering plastics. Our facility spans 1,000–3,000 square meters, staffed by 51–100 skilled professionals, and we export our high-quality components to markets across North America, South America, Europe, Asia, Africa, and Oceania. With a strong commitment to quality and innovation, we deliver parts that meet the rigorous demands of modern electric vehicle assembly, backed by our IATF 16949:2016 certified manufacturing processes.
Our injection molding service is designed for components that require exceptional dimensional stability, long-term reliability, and resistance to deformation under load and temperature. Whether you need connectors, brackets, housings, or custom structural elements for NEV battery packs, charging systems, or powertrain assemblies, we provide tailored solutions that combine engineering expertise with cost-effective production.
Key Product Features & Technical Specifications
- Creep-Resistant Engineering Plastic Materials: Our parts are manufactured using high-performance thermoplastics (e.g., PPS, PEEK, or PA66+GF) that exhibit minimal creep under sustained mechanical stress, ensuring long-term shape retention and reliable performance in NEV applications.
- IATF 16949:2016 Certified Quality Management: Every production step – from mold design to final inspection – follows the strict automotive industry standard, ensuring process control, traceability, and defect prevention.
- High Precision & Complex Geometry: With advanced injection molding machines and precision molds, we achieve tolerances as tight as ±0.01 mm, enabling the production of intricate and thin-walled components.
- Customizable Designs: We offer full customization – from material selection to color, dimensions, and surface finish – to match your specific NEV assembly requirements.
- Excellent Thermal & Chemical Resistance: Our engineering plastics withstand high operating temperatures (up to 250°C for some grades) and resist exposure to automotive fluids, coolants, and battery electrolytes.
- Lightweight & Durable: Injection-molded plastic parts reduce overall vehicle weight, contributing to improved energy efficiency and range, without compromising mechanical strength.
- Fast Prototyping & Mass Production: We provide rapid tooling for prototypes and scalable production runs from hundreds to millions of units, with consistent quality.

Benefits for Your NEV Assembly
- Enhanced Reliability: Creep resistance ensures that critical components like battery module brackets or charging port housings maintain their shape and function over the vehicle’s lifetime, even under continuous stress and temperature fluctuations.
- Cost-Effective Production: Injection molding offers high repeatability and low per-unit cost for large quantities, reducing your overall component expenditure.
- Faster Time-to-Market: Our experienced team works closely with your engineers to optimize designs for manufacturability, reducing prototyping cycles and accelerating production ramp-up.
- Global Compliance: All parts are manufactured under IATF 16949:2016 quality systems, ensuring they meet the strict requirements of automotive OEMs and Tier 1 suppliers worldwide.
- Eco-Friendly Options: We can utilize recycled engineering plastics or bio-based materials upon request, supporting your sustainability goals.

Frequently Asked Questions (FAQ)
1. What types of creep-resistant plastics do you use for NEV parts?
We commonly use materials like PPS (polyphenylene sulfide), PEEK (polyether ether ketone), and PA66+GF (glass-fiber reinforced nylon). However, we can also work with other engineering plastics based on your specific performance requirements. Please provide your material specifications or application conditions, and we will recommend the best option.
2. Can you produce parts with complex geometries or thin walls?
Yes, our advanced injection molding machines and precision molds allow us to produce intricate geometries, thin walls (down to 0.5 mm), and tight tolerances. We use simulation software to optimize mold design and ensure fillability and structural integrity.
3. What is the typical lead time for custom molds and first samples?
Lead time depends on part complexity and mold size. Generally, mold fabrication takes 20–40 working days, and first sample production can be completed within 5–10 days after mold approval. We offer expedited services for urgent projects.
4. Do you offer material testing or certification for each batch?
Absolutely. Under our IATF 16949:2016 quality system, we conduct material identification, mechanical property testing, and dimensional inspection. We can provide a Material Test Report (MTR) and Certificate of Conformance (CoC) for each shipment upon request.
5. Can you handle low-volume orders for prototyping or small series?
Yes, we support low-volume production (e.g., 100–1000 pieces) for prototyping, pilot runs, and niche applications. We use standard molds or rapid tooling to minimize initial investment. High-volume production is also available with fully automated processes.
6. What surface finishes and colors are available?
We offer a wide range of surface finishes: glossy, matte, textured (e.g., MT-11010), or as per your sample. Colors can be matched to any RAL or Pantone code, or we can provide custom color compounding. All finishes are durable and UV-resistant (if required).
7. How do you ensure the parts meet NEV safety and performance standards?
Our manufacturing process is IATF 16949:2016 certified, which includes rigorous control plans, process failure mode effects analysis (PFMEA), and statistical process control (SPC). Additionally, we perform in-house tests for creep resistance, thermal cycling, and chemical resistance to ensure compliance with automotive OEM standards.
8. What are your shipping options and ports?
We ship from major ports in Jiangsu, Shanghai, and Shenzhen, China. We work with reliable freight forwarders to offer sea, air, and express delivery. For international orders, we can arrange door-to-door shipping or FOB/CIF terms as per your preference.
