Helmet Shell Forming Process': Injection molding.'
Features ：1. Impact resistance, especially excellent protection performance against falling objects hitting the top of the head. From the outer shell to the wearer's head, there are four levels of shock absorption structure: a high-strength shell, high-density foam, a wide cushioned cross strap and helmet hoop Ⅰ, and an even-force buffer net and helmet hoop Ⅱ, which minimize the impact intensity and local impact on the skull.
2. Excellent high-temperature resistance performance. Because the shell uses imported PA66/R reinforced polyamide fiber and is flame-retardant treated, the helmet ring uses plastic steel material to provide overall support to the shell shape, the face shield uses high-temperature resistant polyimide material, and the shoulder cover uses glass fiber aluminum foil cloth; navy blue all-cotton oil-resistant flame-retardant twill, double-layer structure, therefore, its high-temperature resistance performance is excellent.
3. More comprehensive protection, adding protection to the ears and the back of the head. When the head is fixed to the helmet ring, the space between each part of the skull and the helmet shell is maintained at more than 3cm, and a comfortable elastic buffer layer is added inside the helmet ring to ensure that accidental impacts will not cause any part of the skull to be directly subjected to force.
4. Multi-level adjustment inside and outside, closely combined with the wearer's head, reasonable weight distribution, stable center of gravity, the tightness of the helmet ring is adjusted by the external rotary knob at the back of the helmet, which can be adjusted at will without removing the helmet, adapting to various head shapes of Chinese people.
5. Comfortable to wear. Because the top of the head uses an even-force net, a multi-level adjustable helmet ring, and the parts of the helmet ring and chin strap that contact the skin use soft, high-quality light lambskin material, which is sweat-absorbing and breathable, comfortable and well-fitting, and the chin strap uses a flame-retardant non-cotton woven strap, which is soft and quick-drying, and will not cause skin allergies in a long-term wet and hot state.
