Qualified helmets, helmets are optional ABS, HDPE or glass fiber reinforced plastic material as raw materials, these types of materials have a high impact resistance, while the inferior helmets almost always recycled waste materials, garbage bags and other plastic products, through the Simple processed. "These are some bad feed back to material that is simply impossible to resist impact, and cost is very cheap, almost more than the price of ABS and other materials is also lower than fifth. Manufacture of plastic shell, some plastic thickness of 2 mm less than the special plastic . In general, a qualified safety helmet weight 360 grams or more, while the poor or even less than 200 grams, the price of course, much cheaper. "

    The man surnamed Huang said technical director, qualified to go through about 20 helmets production process, product colors are the same inside and outside, there is no mottled, lined with high-quality fiber ribbon is made, while the low-grade helmet shell Some spray the paint, lining made of the overall injection molding, there are specific spots the old materials, workmanship rough, there are unpleasant odor.
