Production Steps of Motorcycle Helmets (1)

Production steps of motorcycle helmets (1)
Helmets are the primary life-saving equipment, and there are many categories of helmets, with different shapes for different sports and uses, such as half helmets, full helmets, open-face helmets, off-road road dual-use helmets, and so on. However, from the manufacturing process, they are roughly the same, knowing how the helmet is made can better allow us to buy and use the helmet. The materials for making helmets are roughly divided into two types, polycarbonate helmets and composite helmets.
Step 1: Making the EPS (Expanded Polypropylene) Helmet Liner
(1) EPS is cheap, light and easy to use. This kind of foam material that can be used to make lunch boxes is a good head protection material. In fact, one of the things that differentiates a regular helmet from a premium helmet is the quality of the polyethylene propylene. Some helmet manufacturers use the same polyethylene propylene material to make the entire lining, while others develop polyethylene propylene linings with different thicknesses, strengths and shapes specifically for the purpose and shape. The latter means that each helmet must have an independent mold and CAD design, which of course means cost.
(2) After the helmet lining mold is finished, generally colleagues will design a lot of holes and channels for heat dissipation, drainage, pressure relief, etc. Generally speaking, each mold only fits one type and size of helmet. It should be noted that a helmet liner is not all made of the same polyethylene propylene material. According to the impact strength that needs to be adapted to different head parts, the polyethylene propylene material on the sides of the helmet and the center of the helmet will be different.
Step 2: Making the Polycarbonate Helmet Shell
Polycarbonate is heavier than composite helmets, but it is also harder. Composite helmets are often scrapped in accidents. Of course, this is not just poor protection. They can be understood as the difference between cast and forged rims. In addition, once hit in an accident, even an undamaged polycarbonate helmet should never be used again, because the helmet lining has already completed the energy-absorbing work and no longer provides the same level of protection. Almost all protective equipment is disposable. Don't expect to continue wearing it if it is not damaged enough to be used. In that case, only the shape is still there, but it no longer has the ability to protect you. It is better to hang it on the wall as a souvenir. Although the production process is completely different, whether it is to make a polycarbonate helmet or a conformal material helmet, it requires investment in professional technology, manufacturing technology, and a lot of money.
