Since April 2020, with the ride electric vehicles must wear a helmet policies proposed that promotion of mainland China helmet in the traditional manufacturing industry has been renewed business trendy, especially the injection molding production and processing industry has been hungry, helmet injection molding machine in recent period of time sales situation is good, the following Powerfulsky Mould to take you from the source to understand how a helmet is made of.
Produce Helmets simply is divided into 4 steps.
1. The helmet liner is made, usually have EPS material
Helmet liner mould shape, after the completion of general designer can design has many holes and channel, the purpose is used for cooling, drainage, release pressure and so on.Generally speaking, each mold one suitable type and size of the helmet.A helmet liner and use are not entirely the same poly ethylene propylene material, according to different head part of the need to adapt to the impact strength, on both sides of the helmet and the helmet in the center of the poly (ethylene propylene material will be different.
2. Make helmet shell composite materials
Process of composite helmet was mostly are classified, each have each patent.Plastic raw material with liquid injection helmet shell mould machine, through the mother die extrusion.Each pair of helmet mold for different size also through the design of CAD/CAM model, from injection to molding, each helmet mold takes about 55 seconds, and then enter the next step, polishing, spraying., and then install the mask to prevent stroke, prevent mist processing mask.
3. Grinding, painting, carve patterns or designs on woodwork processing
Surface after treatment, the helmet can spray paint and decals, decals done by computer design and print, performed by artificial post system.Finally through polishing treatment after a helmet is basic production finished.
4. Assembly, packaging and delivery
Next appearance after processing the helmet will install all kinds of needed parts, at the same time in the process, the staff will be the final quality inspection, including crash test sampling each part, the thickness of the examination and so on, finally after a package transportation,
