Many manufacturers of plumbing equipment have requirements on the surface texture and flatness tolerances of their products, especially floor drains, because there are many small holes on the surface of the floor drain or a round hole in the center.
The general equipment is easy to cause collapse in the process of drawing. The surface tolerance is very different. The water mill produced by our company adopts the fine grinding processing technology and the working principle of uniform cylinder pressure, so that the product surface tolerance is controlled within 2 wires, and the texture is straight and uniform, and there is no sag The phenomenon.
