Ordinary helmet injection mold

1. Motorcycle Helmet: Tailored to Riding Scenarios

① Urban Commuting (Daily City Rides)

Key needs: Ventilation, portability, and low-noise.

Helmet features: Half-face design (weight ≤1.2kg, easy to take on/off for short stops), 6-8 adjustable ventilation holes (airflow rate ≥15L/s to reduce sweating in traffic jams), and a detachable noise-reducing chin curtain (cuts wind noise by 25% at 60km/h). Complies with CE EN1078/CPSC standards, with a PC/ABS shell (impact resistance ≥60kJ/m²) and EPS buffer layer (density 40kg/m³) to protect against low-speed collisions (common in city traffic).

② Long-Distance Touring (Highway & Cross-Country)

Key needs: Comfort, weather resistance, and visibility.

Helmet features: Full-face design with a anti-fog visor (UV protection rate 99%, clear vision in rain/fog) and a removable moisture-wicking liner (machine-washable, prevents odor after long rides). The shell adds a rear air spoiler (reduces wind resistance by 18% at 100km/h) and reflective strips (360° visibility for night riding). Interior space is expanded by 5% to fit prescription glasses, solving the pain point of glasses wearers.

③ Racing (Track Riding)

Key needs: Lightweight, high impact resistance, and wide 视野.

Helmet features: Carbon fiber-reinforced PC shell (weight ≤1.0kg, 30% lighter than standard shells), EPS buffer layer with multi-density zones (20kg/m³ for high-impact areas, 50kg/m³ for shock absorption), and a 180° flip-up visor (wide field of view, no blind spots for track turns). Meets FIM Racing standards, with a chin vent that channels air to cool the face (reduces internal temperature by 3-5℃ during high-intensity riding).

2. Bicycle Helmet: Matching Riding Types

① Mountain Biking (Off-Road Trails)

Key needs: Rear head protection, anti-slip, and durability.

Helmet features: Extended rear shell (covers 30% more of the occipital region, common impact area in falls), 12-16 large ventilation holes (dust-proof nets inside to block mud/leaves), and a non-slip adjustable strap (rubber texture, no sliding when sweating). The shell uses impact-resistant ABS (tensile strength ≥50MPa), and the head circumference adjustment dial (fits 54-62cm) ensures a tight fit on bumpy trails.

② Road Cycling (Speed Racing)

Key needs: Aerodynamics, lightweight, and breathability.

Helmet features: Streamlined aerodynamic shape (reduces wind resistance by 22% at 40km/h), ultra-light EPS core (weight ≤250g), and a honeycomb ventilation structure (airflow efficiency increased by 20% to cool the scalp). The visor is detachable (for flat terrain) and the strap has a quick-release buckle (easy to adjust during rides). Complies with UCI regulations for road races.

Scenario-Based Buying Guide

Choose half-face helmets for city motorcycle commutes, full-face for long tours/racing; for bicycles, pick extended-rear helmets for mountain trails and aerodynamic models for road rides. Prioritize helmets with certified safety standards (CE/CPSC) and scenario-specific features to balance protection and comfort.
