Integrated molding and non integrated molding are two different manufacturing processes.

One piece Electric vehicle helmet It refers to that the electric vehicle helmet manufacturer puts the plasticized PC shell and foam material into the molding machine to form the product once. The whole helmet is a whole, with strong resistance and strength, suitable for head protection. It's better, too. In case of danger, the helmet will deform and break, which can effectively reduce the force of head hitting the ground and protect the head. The non integrated electric vehicle helmet means that the foam is formed first, and then the blister PC or PVC blister shell is covered on the foam.

By looking at:

We picked up the electric helmet in our hands and carefully observed the perforated area and the edge of the helmet. You can easily find fake one-piece electric vehicle helmets because of the manufacturer's technology level, because there is a small space in these areas, almost every hole has this phenomenon. This is not the case with a real one-piece electric helmet. Because it directly injects EPS into the cap shell, just like we pour concrete beams, there is no space between the formwork and the concrete, which is a perfect combination.

By touching:

Just touch these places up and down, left and right with our most sensitive fingers. Very shaved hands, because it can not be well combined and has free space. Moreover, the one-piece electric bicycle helmet is perfectly integrated, without a little space, and naturally will not scratch our hands.

By listening:

It is to hold the electric vehicle helmet with one hand, and knock the electric vehicle helmet with the other hand everywhere. At this time, you will hear the sound that normal things are empty. The sound of the announcement or the sound that is about to be broken but not broken is not clear but muddy, so the electric vehicle helmet must be a fake one. The sound of a real integrated electric bicycle helmet when it hits is like the sound of our solid wood furniture. The image recognition is very clear and the hand feel is very solid.
