Production steps of
motorcycle helmets (2)
It is increasingly popular among manufacturers of polycarbonate helmets to use copolymer resin materials, which have better impact resistance and thermal resistance than ABS resin. On the other hand, the material can also be better matched with environmentally friendly water-based coatings. The resin is injected into the helmet shell mold machine in a liquid state, and is extruded through the sub-mold mold. Each helmet mold is also designed with CAD/CAM models for different sizes. The molds used to manufacture helmets have a life cycle. Each time a new helmet is launched, a batch of molds will be eliminated. From injection to molding, each helmet mold takes about 60 seconds, after which it moves on to the next step, sanding, painting, and decals. Then install the mask, and apply anti-scratch and anti-fog treatment to the mask.
The third step: grinding, painting, carving treatment
One advantage of polycarbonate helmets is that once the mold is completed, the mask and other moving parts can be directly installed, because all holes in the polycarbonate helmet are reserved during the molding process, and no subsequent drilling is required. Some manufacturers use mechanized processes in the helmet grinding process, while others maintain manual processing. After the surface is treated, the helmet will be painted and decals. The decals are designed and printed by computer, and then finished by hand. Finally, after polishing a helmet, the production is basically completed. After the appearance treatment of the helmet, various required parts, visors, masks, etc. will be installed next, and at the same time, the final quality inspection of the staff will be accepted during this process, including thickness inspection of each part, impact test sampling and so on.
