As a professional manufacturer based in Changzhou, Jiangsu, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. specializes in precision thin-wall injection molding for annular OEM parts. Established in 2017, we operate a 1,000–3,000 m² factory with 51–100 skilled employees, and we hold TS16969 certification—a testament to our commitment to quality in the automotive and industrial sectors. Our engineering plastic components are engineered with creep resistance and dimensional stability, ensuring long-term reliability in demanding applications. Whether you need custom annular parts for automotive systems, electronic housings, or medical devices, our precision molding solutions deliver consistent performance and tight tolerances.
Our thin-wall injection molding process is designed to produce lightweight yet strong annular components with wall thicknesses as low as 0.3 mm. By using advanced engineering plastics such as PEEK, POM, PA66, and LCP, we achieve excellent creep resistance, high mechanical strength, and superior dimensional stability even under thermal or mechanical stress. This makes our parts ideal for applications where precision and durability are critical.
Key Features & Technical Advantages
Ultra-Precision Thin-Wall Molding: Achieve consistent wall thickness from 0.3 mm to 2.0 mm with tight tolerances of ±0.02 mm – ±0.05 mm, depending on material and geometry.
Creep Resistance: Engineered plastics maintain their shape and mechanical properties under continuous load, preventing deformation over time.
Dimensional Stability: Low moisture absorption and low thermal expansion ensure parts retain their critical dimensions across a wide temperature range (-40°C to +150°C).
Custom Material Options: We support a wide range of engineering plastics, including reinforced grades (glass fiber, carbon fiber) for enhanced stiffness and strength.
Annular & Complex Geometries: Our molds are designed to handle intricate annular shapes, internal threads, undercuts, and tight radiuses with high repeatability.
Surface Finish Flexibility: Choose from glossy, matte, or textured finishes to match your aesthetic or functional requirements.
TS16969 Certified Process: Our production line follows automotive-grade quality standards, including statistical process control (SPC) and full traceability.
Cost-Effective for Medium to High Volumes: Optimized cycle times and multi-cavity molds reduce per-part cost without compromising quality.

Why Choose Our Precision Thin-Wall Injection Molding?
Our annular OEM parts are trusted by clients across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. With a dedicated team of engineers and mold designers, we offer complete turnkey solutions from DFM (Design for Manufacturability) to production and logistics. The TS16969 certification ensures that every part meets rigorous quality standards, including dimensional verification, material certification, and functional testing.
We understand that thin-wall parts require precise control of injection speed, pressure, and cooling. Our modern injection molding machines (80–500 tons) are equipped with servo-driven systems and advanced temperature controllers to achieve consistent results. Additionally, we provide optional secondary operations such as ultrasonic welding, insert molding, and assembly to simplify your supply chain.
If you are looking for a reliable partner for precision thin-wall annular components with creep resistance and dimensional stability, contact us today. We offer free DFM analysis, competitive pricing, and fast sample delivery. Let us help you bring your OEM project to life with confidence.
Frequently Asked Questions (FAQ)
Can you achieve thin walls below 0.3 mm?
Yes, we can mold walls as thin as 0.2 mm for certain materials like LCP, but this is highly dependent on part geometry. We recommend a DFM review to confirm feasibility.What engineering plastics offer the best creep resistance?
PEEK, PPS, and glass-filled PA66 are excellent choices. Our material selection guide can help you choose based on temperature, load, and chemical exposure.Do you provide mold design and prototyping services?
Absolutely. We offer full mold design, prototyping (3D printing or soft tooling), and production molds. Our engineers work closely with you to optimize the design for manufacturability.What is the typical lead time for production?
Mold manufacturing takes 20–45 working days, depending on complexity. First article samples are usually available within 10–15 days after mold completion.Can you handle large-volume orders?
Yes, our factory capacity supports medium to high volumes (up to several million parts per year) with multi-cavity molds and automated production lines.Do you offer any surface treatment or coating?
We can provide optional surface treatments like painting, plating, or laser marking upon request. Please discuss your specific requirements with our sales team.How do you ensure dimensional stability in thin-wall parts?
We use advanced simulation software (Moldflow) to optimize gate location, cooling, and packing. In-process SPC monitoring and CMM inspection guarantee tight tolerances.What is your shipping policy for international orders?
We ship from Jiangsu, Shanghai, or Shenzhen ports via sea, air, or express. We can arrange door-to-door delivery and handle customs clearance for most destinations.
Backed by 51–100 experienced employees and a 1,000–3,000 m² state-of-the-art facility, Changzhou Hongxinyutai Precision Mold Co., Ltd. is your trusted partner for precision thin-wall injection molding.
