The flap discs production is a complicated process. Every production step  is very important and related to flap disc's quality. Therefore, producing a qualified flap disc must focus on the following aspects.

1.The evenly arranged flaps

When we grind workpiece, rotational speed is a very important factor, which directly affects the grinding quality. The evenly arranged flaps can make the flap discs rotate at uniform speed. The worker will be safer and the polishing quality will be better. Yihong uses fully automated production machines to ensure that each flap is evenly arranged.

2.The evenly distributed sand grains

Sandpaper is used to grind the workpiece. Uneven distribution of sand particles will cause congestion. The evenly distributed sand can make the grinding effect better, and the surface of the workpiece is smoother.

3.The ratio of glue

In the production of flap discs, the flaps need to be fixed on the matrix with glue. If the glue is too little, the flaps will not stick firmly. In the process of use, high speed rotation will make the flaps fall off, which is easy to hurt workers. If there is too much glue, it will spill over the surface and influence the use affect of flap discs. After many experiments, Yihong has worked out the best amount of glue and improved the quality of flap discs.

4. Quality of the backing plate

As the base of flap discs, the quality of the backing plate is directly related to the quality of flap discs. Therefore, the quality of the backing plates is also very high. Yihong provides backing plates with appropriate layers to ensure the safety. Our speed of backing plates is in line with international safety standards EN13743. Yihong backing plate international market is up to the top 1 in the world.
