Bicycling is a worldwide activity. In both developed and developing countries it serves as an important means of transportation as well as an enjoyable recreational activity for adults and children. Thus, injuries related to bicycling are comparatively common, and head injuries account for one third of visits to emergency departments, up to two thirds of hospitalisations, and three quarters of deaths.1 Head injuries also carry a substantial risk of long term disability. Thus, preventing head injuries associated with this common, worldwide activity is important.
Usually, the shell of the helmet is made of high-strength materials, such as metal, engineering plastics, Kevlar fiber, etc., through its deformation to absorb most of the impact; the lining material has the ability to absorb sweat, keep warm, and absorb shock. Military helmets often have the functi
The helmet manufacturing process transforms raw materials like ABS, EPS, and EVA into a certified, impact-absorbing finished product through six core stages: material preparation, shell forming, EPS foam molding, assembly, quality inspection, and safety testing. Each stage combines precision enginee
Helmet safety certifications are mandatory compliance standards that verify a helmet can protect its wearer under defined impact conditions. The three most widely recognized helmet standards are CE (Europe), CPSC (United States, consumer products), and ASTM (United States, sport-specific). Each appl
To verify a helmet supplier's quality, importers should evaluate five core areas: factory credentials and audit results, safety certifications (CE, CPSC, ASTM), sample testing outcomes, production capacity, and quality management systems. Skipping any one of these steps significantly increases the r
