A Brief Introduction of Flap Disc

Flap disc is a large variety of abrasive conversion products. Flap disc consists of many pieces of abrasive cloth adhere to one coaster in the form of one pinned by another. Those abrasive cloths are displayed homogeneously like a fan to guarantee the best grinding effect. Every piece of abrasive cloth has a angle with coaster between 10º to 30º. Substrate of abrasive cloth can be made from diversified materials, such as net cloth, nylon, plastic and vulcanized fiber. Abrasive grains used in flap discs usually includes corundum, zirconium corundum and silicon carbide, and their grit ranges from 36#—600#, among which 60# and 80# are the most common.  

Flap disc is mainly installed on the hand-held electric tools and used for grinding and polishing metal and non-metallic surfaces in ship, automobile, aviation, machinery, instrument, bridges and furniture. Flap disc has advantages over coated abrasives resin grinding wheels in good elasticity, good heat dissipation, and low noise. The application of flap discs can finish grinding and polishing in one-time, which greatly shorten the operation time, reduce the polishing cost and improve the grinding efficiency. Moreover, self-sharping of grits on flap disc is strong, their utilization rate is high, and quality of flap disc surface is easy to control, therefore flap discs are widely used in manufacturing industries. 

Due to its superior performance, flap discs are always in great demand in the market, especially in the industrial developed country. Traditional flap disc production process is complex, including cutting, slitting, cutting piece, placing piece, dropping gum, wearing rod, curing, selection, labeling and other processes. Then the process of placing pieces is divided into displaying pieces, pushing button, retouching, wearing t. In the early days, the whole production process still relied on intensive manual labor. To some extent, that situation has hindered the improvement of product quality and reducing production cost, and restricted the development of the enterprise. As a result,  the production of flap disc transforms from manual to automation machinery operation has become inevitable. Where there is demand there is market. When finding this chance, there are several abrasives manufacturers engaged in producing automatic flap disc machine, and Dongguan Yuda Abrasives Technology Co., Ltd. is one of them. As early as in 2012, Dongguan Yuda has successfully hosted the full automatic machine promotion fair. Compared with other automatic flap disc machine in the market, Dongguan Yuda’s machine has the capacity of detecting the thickness of the substrate, and can independently design glue system and gumming, which make Dongguan Yuda enjoy high reputation in the industry.
