This casting process forms the helmet shell, ensuring uniform wall thickness and structural consistency. The mold design is critical for achieving the specific shape required for impact distribution and ventilation.
3. Cooling and Ejection: After injection, the molten HDPE cools rapidly within the mold, solidifying into the helmet shell. Once sufficiently rigid, the mold opens, and the shell is automatically ejected. Controlled cooling parameters prevent warping and internal stresses.
4. Trimming and Finishing: Excess material (flash) from the molding process is carefully trimmed. Edges are smoothed to remove any sharp points, ensuring user comfort and preventing snags. Ventilation holes, if part of the design, are precisely punched or drilled.
5. Suspension System Assembly: The internal suspension system, which typically includes a head harness, sweatband, and adjustable ratchet mechanism, is assembled and integrated into the helmet shell. This system is crucial for absorbing impact energy, distributing weight, and providing a secure, comfortable fit. The suspension system often incorporates textile straps or plastic webbing for flexibility and comfort.
6. Accessory Integration: Depending on the helmet's intended use, slots for accessories like earmuffs, face shields, or headlamps are added. For customized solutions, OEM printing of company logos or safety instructions is performed using durable, fade-resistant methods.
7. Quality Control and Testing: Each batch undergoes rigorous testing to ensure compliance with international standards such as ANSI Z89.1 (Type I, Class E, G, or C), EN 397, and ISO 3873. Tests include impact resistance (vertical and lateral), penetration resistance, flammability, and electrical insulation (for Class E and G helmets). Visual inspections for defects and functional checks of the suspension system are also performed.
8. Packaging: Approved helmets are cleaned, individually packaged, and prepared for distribution.

This intricate process ensures that every engineering safety helmet not only meets but often exceeds the demanding requirements of various industries, providing reliable head protection for workers.
