THE CHALLENGE

Complex Geometry with Optimized Flow Dynamics

Our client needed automotive impellers with complex curved geometries optimized for maximum flow efficiency. The challenge was maintaining precise blade angles and surface finish while using glass-filled nylon for strength and durability.

The impeller design featured intricate flow channels and varying wall thicknesses that were difficult to mold consistently. Any dimensional variations could significantly impact performance and cause vibration issues.

High-volume automotive production required robust processes capable of producing 75,000+ units annually with zero tolerance for defects.

THE SOLUTION

Advanced Injection Molding with Flow Optimization

Stone Plastics developed a specialized injection molding process using glass-filled nylon with optimized flow characteristics. We created complex tooling with advanced cooling systems to manage the varying wall thicknesses.

Our engineering team used flow analysis software to optimize gate placement and injection parameters. The process includes real-time monitoring of key parameters to ensure consistent part quality.

The solution included: • Complex multi-cavity tooling with advanced cooling • Glass-filled nylon material optimization • Flow analysis and gate placement optimization • Real-time process monitoring and control • Automated balancing and flow testing • Statistical process control implementation
