Changzhou Hongxinyutai Precision Mold Co., Ltd. is a dedicated manufacturer with over 7 years of experience in precision injection molding. We specialize in thin-wall injection molding services for OEM NEV components, using creep-resistant plastics to ensure long-term reliability under demanding conditions. Our IATF 16949 certified facility and 100% CMM dimensional verification guarantee that every part meets the tightest tolerances required by the automotive industry.
With a factory size of 1,000–3,000 square meters and a team of 51–100 skilled employees, we are fully equipped to handle projects from prototype to mass production. Our thin-wall molding technology enables the production of lightweight, high-strength components that reduce vehicle weight and improve energy efficiency — critical for modern NEVs.
Key Features of Our Thin-Wall Injection Molding Service
- Creep-Resistant Materials: We use advanced engineering plastics such as PBT, PA66, and LCP that maintain dimensional stability under continuous load and high temperature.
- IATF 16949 Certification: Our quality management system is fully compliant with the automotive industry standard, ensuring consistent, defect-free production.
- 100% CMM Dimensional Verification: Every part is inspected with coordinate measuring machines to guarantee ±0.02 mm tolerance where required.
- Thin-Wall Capability: Achieve wall thicknesses as low as 0.3 mm without compromising strength or cycle time.
- OEM Support: We work directly with NEV manufacturers to design molds and optimize part geometry for cost-effective mass production.

Frequently Asked Questions
Q1: What is the minimum wall thickness you can achieve?
We can consistently produce parts with wall thickness as low as 0.3 mm, depending on material and geometry. For complex designs, we recommend a minimum of 0.4 mm to ensure proper fill and mechanical strength.
Q2: Which creep-resistant plastics do you recommend for under-hood NEV components?
For high-temperature and creep-critical applications, we often recommend PBT (e.g., Valox®), PA66 (e.g., Zytel®), or LCP (e.g., Vectra®). Our engineers will help you select the best grade based on thermal, mechanical, and chemical requirements.
Q3: Is your IATF 16949 certification valid for the full scope of injection molding?
Yes, our IATF 16949 certification covers the design, production, and inspection of plastic injection molded parts for automotive applications. We undergo regular audits to maintain compliance.
Q4: How do you ensure dimensional accuracy on thin-wall parts?
We use 100% CMM dimensional verification for critical dimensions. For high-volume production, we also implement statistical process control (SPC) and in-process gauging to maintain consistency.
Q5: What are typical lead times for mold building and first articles?
Mold fabrication typically takes 4–6 weeks, and first article samples are delivered within 2 weeks after mold completion. Expedited services are available upon request.
Q6: Can you handle high-volume production for NEV battery components?
Absolutely. Our factory has the capacity to produce millions of parts per year. We can set up dedicated production cells and automated inspection systems to meet your volume requirements.
Q7: Do you offer design assistance for thin-wall injection molding?
Yes, our engineering team provides DFM (Design for Manufacturing) analysis to optimize wall thickness, gate location, and cooling to reduce warpage and cycle time. We also recommend material selection based on creep resistance and other performance criteria.
Q8: What shipping ports do you use for international orders?
We ship from Jiangsu, Shanghai, and Shenzhen ports. We have experience exporting to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East.
