Electric vehicle helmet It can play a role in maintaining the safety of the driver's head. Generally, electric vehicle helmets are equipped with foam buffer layers. Manufacturers of electric vehicle helmets generally make helmets from two materials: polycarbonate data helmets and composite data helmets (such as carbon fiber). Do you know how helmets are made, Next, the electric vehicle manufacturer will take you to see the helmet production process and increase knowledge.

Manufacturing process of electric vehicle helmet

The production process of electric vehicle helmets can be roughly divided into four steps: shell fabrication, hat core fabrication, polishing/coating treatment, assembly/packaging.

Step 1: shell fabrication

The production of polycarbonate helmet shell uses the data of copolymer resin, which has better impact resistance and thermal resistance than ABS resin (acrylonitrile styrene butadiene copolymer). On the other hand, this information can also be better used with environmentally friendly water-based coatings. The resin is injected into the helmet shell mold machine in liquid state, and is formed by kneading the parent mold. Each helmet mold is also planned through CAD/CAM model for different sizes. The mold used to make the helmet has an application cycle. Each new helmet will eliminate a batch of molds. Each helmet mold takes about 60 seconds from injection to molding.

Step 2: Manufacturing of cap core

With EPS (expandable polyethylene propylene) helmet fabric, EPS is not only cheap and light, but also a good head maintenance material. In fact, one of the differences between an ordinary helmet and a high-quality helmet is the quality of polyethylene propylene. For example, some helmet manufacturers use the same polyethylene propylene materials to make the entire fabric, while others develop polyethylene propylene fabrics of different thickness, strength and shape specifically for use and modeling. After the molding of helmet fabric mold is completed, there will be many holes and channels planned in the helmet mold, which are intended to be used for heat dissipation, drainage, pressure release, etc.

Step 3: Grinding and coating

In the helmet polishing process, some manufacturers use mechanical processes, while others still use manual methods. After the surface is treated, the helmet will be painted and pasted. The decals will be planned and printed by the computer, and then pasted manually. Finally, a helmet is basically finished after polishing.

Step 4: assembly and packaging

After the completion of the helmet process, the manufacturer of electric vehicle helmets will assemble the helmet accessories, conduct random sampling inspection, and complete the packaging process.
