The advantages and disadvantages of plastic rod brush roller and metal rod brush roller

The brush roller is generally composed of a metal shaft, a brush wire attachment, and a brush wire. There are generally two types of filament attachments for brush rollers, one is a plastic rod, and the other is an aluminum rod. The process flow of the brush roller is axle, casing, eye picking, planting, and flat hair. Let me give you an analysis of the advantages and disadvantages of these two brush rollers. Plastic rod brush roller: The plastic rod brush roller refers to the material of the brush filament attachment is plastic rod. This is an indirect tufting type. Its advantages and disadvantages are as follows: Advantages: good tufting strength, short process manufacturing cycle, and partial replacement , The metal shaft core in the middle can be reused after a long time. Relatively speaking, the production cost of this brush roller is lower and the price is cheaper. Disadvantages: The processing technology is relatively complicated. The plastic rod is the attachment of the brush wire, the middle is hollow, and the metal shaft core should be covered in the middle. The thermal expansion and contraction characteristics of the plastic cause the plastic rod to be easily deformed. This process is easy to break hair and remove hair. The aluminum rod brush roller means that the brush filament attachment of the brush roller is an aluminum rod, which belongs to the direct tufting type and does not need to be tufted through other media. Its advantages and disadvantages are as follows: Advantages: simple production process, high density of flocking, advanced technology. The bearing position and pulley position are directly made without hair removal or broken hair. The brush roller of any length can be made, and the aluminum has good stability and is not easy to deform. Disadvantages: The technical requirements are high. Because the wool is directly planted on the metal, partial replacement cannot be performed, and the production cost is high. It is not suitable for making brush rollers made of metal brush filaments.
