Nowadays, there are probably the following ways to make the grinding roller:
Direct hair planting
This is the oldest way, that is, the abrasive silk is directly planted on the grinding roller, although the strength can reach a high level, but the cost of hair planting is high, and it can not be replaced locally, which is the initial helpless choice.
Winding
is a method of planting wool introduced abroad, which makes abrasive silk into a metal strip that can be wound and then wrapped on the grinding roller. It can be customized according to the length of the grinding roller, but because the abrasive wire is stuck on the metal strip, it will lead to the phenomenon of wire drawing (abrasive wire is extracted), the strength is not high, and the two ends are fixed after winding, so the middle is difficult to do tight, if one end is loose, it will cause accidents.
Nylon sleeve
Although it can be convenient to make, but the problems are also the most one, the thermal expansion and contraction of nylon will cause nylon to become longer, and the nylon at both ends of the roller body will grow out of the grinding roller and resist the machine; The use of riding nails to plant bristles, the strength is not high, easy to remove hair; The thermal expansion and cold contraction of nylon will also cause the nylon sleeve to expand and crack, and the whole grinding roller will be scrapped. Nylon strength is not high, can not improve the planting density and so on... . Although many foreign manufacturers make it, the problems exposed are the most.
Aluminum alloy brush plate - New grinding roller
is the world's grinding roller, produced with 20cm brush plate splicing, can be customized any length of the brush roller; The high-strength aluminum alloy substrate can make the hair planting density high, and the hair planting technology used to ensure that no hair removal, not to crack like nylon, long phenomenon; The roller body can accurately check the dynamic balance. What's more, the use of this brush roller is really fast replacement, fast trimming, infinite extension. Choose this brush roller, in order to be carefree.
