Bicycle helmets are mainly composed of an outer shell and a foam liner. According to the production molding process, it can be divided into integrated molding and non-integrated molding. Simply put, the one-piece Urban Bike Helmet is to press the plasticized PC shell and EPS into the mold at one time. The shell and the foam are one piece with no gaps. The PVC shell was glued together by hand with a noticeable gap between the shell and the foam. A one-piece helmet shell will have a better fit between shell and liner, provide better head protection, and be more responsive. Regardless of whether there is a skeleton inside, the top helmet can improve the overall strength of the helmet by laying the skeleton on the inner lining, preventing the inner lining of the helmet from breaking during a strong impact and losing the protection of the legs and head. Previously this technique was used for special. In recent years, with the maturity of technology, it has gradually spread to other levels. Pay attention to this parameter when choosing.
Of course, the helmet manufacturer stated that the reinforcement structure design of the bicycle helmet mainly refers to several related aspects, such as the multi-directional impact protection system. There are yellow partitions inside, which can ease the impact from all directions and angles when the head collides, reduce the impact strength of the brain, and avoid the spine. Because twisting can cause more serious injuries. The weight directly affects the wearing feeling. Too heavy will increase the pressure on the neck, and wearing it for a long time will cause neck pain, so the lighter the weight, the better.
However, helmet manufacturers point out that the design cannot be too thin to pass standard safety certification, so most bicycle helmets weigh between 200g-300g. Almost none of the products sold on the market below 200 grams can guarantee safety. Because this poses a huge challenge to the design of the structure. If you see that it is very light, about 200 grams or less, and it is not a well-known brand, you should pay attention to whether there are any cut corners.
According to the manufacturer of Bike Helmet, according to the structure, it can be divided into two types: integral molding and non-integral molding. One-piece molding refers to putting the plasticized PC shell and foam material into the molding machine to form the product at one time. The shell and the cap body have a better fit and greater strength, which can better protect our head. Non-integrated molding means that the foam is formed first, and then the blistered PC or PVC blister shell is placed on the foam. The strength is relatively weak. But the price is a little cheaper.
