Advantages and disadvantages of plastic roller brush roller and metal rod brush roller

　The brush roller is usually made of metal shaft, brushed wire and brushed wire. There are two kinds of brushes of brushed roller, one is plastic rod and the other is aluminum rod. The process flow of brush roller is the axle, casing, eye, hair, and hair. Let me give you an analysis of the advantages and disadvantages of the two brushes.
　Plastic rod brush roller: plastic rod brush roller is the material of the brush attachment body is plastic rod, this kind is the indirect planting hair type, its advantages and disadvantages are as follows:

　Advantages: good flocking strength, process manufacturing cycle is short, can replace locally, use for a long time in the middle of the metal shaft core can be repeated use, relatively, the brush roller production costs are lower, prices are cheaper.
　Disadvantages: the processing technology is relatively complicated, the plastic rod is the attachment of the brushed wire, the center is hollow, and the center shall be set on the metal shaft core, the plastic heat expansion and condensation characteristics lead to easy deformation of plastic rods. This process is brittle and depilatory.
　The brush roller of aluminum rod is the brush thread of the brush roller which is the aluminum rod, which belongs to the direct flocking type, and no longer need to be planted by other media. The advantages and disadvantages are as follows:
　Advantages: simple production technology, high density and advanced technology. Direct bearing position, pulley level, no hair removal, broken hair. Can make any length of the brush roller, aluminum stability is good, not easy to deform.
　Disadvantages: high technical requirements, due to the direct metal flocking, no local replacement, high production cost. It is not suitable for the wool brush roller of the material.
