THE CHALLENGE

Large-Scale Production of Impact-Resistant Helmet Shells

Our client needed to scale production of safety helmet shells that met stringent impact resistance standards while maintaining lightweight properties. The challenge was achieving consistent wall thickness and structural integrity across large production volumes.

The helmet shells required integrated ventilation systems and mounting points for accessories, adding complexity to the molding process. Quality standards demanded zero tolerance for structural defects that could compromise safety.

Production volumes of 100,000+ units annually required efficient processes and minimal waste to maintain competitive pricing.

THE SOLUTION

High-Volume Injection Molding with Integrated Features

Stone Plastics implemented a large-tonnage injection molding solution using ABS/PC blend materials optimized for impact resistance. We designed multi-cavity tooling to maximize production efficiency while maintaining part quality.

Our process included integrated molding of ventilation channels and mounting features, eliminating secondary operations. Advanced process monitoring ensured consistent wall thickness and structural integrity.

The solution included: • Large-tonnage injection molding presses (300+ ton) • Multi-cavity tooling for high-volume production • Integrated ventilation and mounting feature molding • Real-time process monitoring and control • Automated quality inspection systems • Impact resistance testing protocols

THE RESULTS

Key Outcomes

1

100,000+ helmet shells produced annually
