Turbo Fan Wheel Injection Molding for Automotive Parts

Our Solution

In this project, the key challenge was to balance high precision and durability while ensuring production efficiency. Here’s how Huashuo Molding solved it:

1. Precise Mold Design
   Our engineering team used advanced CAD software to design molds, ensuring that every detail of the turbo fan wheel met the required specifications for automotive turbochargers. During the design process, we focused on key factors such as:
   • Plastic Shrinkage Rates: Different materials have different shrinkage rates that directly impact mold precision. For example, Nylon has a shrinkage rate of about 0.8% to 1.2%, while PBT is lower. We precisely calculated these factors to ensure consistent and accurate part dimensions.
   • Cooling Channel Design: To improve production efficiency, we optimized the mold’s cooling system to ensure even cooling of the plastic material. The cooling cycle was controlled within 3 to 5 minutes, reducing the overall production time per batch.
2. Efficient Mold Manufacturing
   For mold manufacturing, we chose hardened steel as the primary material, ensuring durability and high precision. Using CNC machining technology, we crafted every detail of the mold with extreme accuracy. The manufacturing cycle was completed within 8 to 12 weeks, meeting the demands of large-scale production.
3. Optimized Injection Molding and Cooling
   During the injection molding process, we heated plastic pellets (Nylon, PP, etc.) to their flowable temperature (around 230°C to 270°C) and injected them into the mold at a pressure range of 1000 to 1500 bar. The carefully optimized cooling system ensured that each turbo fan wheel was cooled within 3 to 5 minutes, maximizing production efficiency while maintaining high-precision molding.

Production and Quality Control

At Huashuo Molding, we prioritize quality control, especially when producing high-demand automotive parts like turbo fan wheels. Each stage of production is meticulously controlled to ensure the final product meets the highest standards.

1. Burr Removal and Post-Processing
   After injection molding, the turbo fan wheels undergo burr removal to ensure smooth edges and eliminate any defects. Depending on customer requirements, we also offer spraying and polishing treatments to enhance the durability and appearance of the fan wheels.
2. Strict Performance Testing
   Every turbo fan wheel undergoes rigorous performance testing, including high-temperature, high-pressure, and anti-aging tests. These tests simulate the extreme conditions in which turbochargers operate, ensuring that each plastic fan wheel performs reliably under high-speed and high-temperature environments.

Results and Customer Feedback

By providing this custom injection molding solution, we helped the client significantly improve production efficiency and reduce costs. The production cycle for plastic fan wheels was shortened by approximately 20% compared to traditional metal fan wheels, while product precision and consistency were significantly enhanced to meet the demanding requirements of automotive turbochargers.

The client reported that the custom plastic fan wheels not only reduced material costs but also improved the overall performance and reliability of their turbochargers. This has helped them maintain a competitive edge in the market.
