During the brushing process, the manual brushing method uses a brush to dip the coating in the small bucket, and the time of brushing after one dipping is very short, and many brush marks are easily generated in the later brushing period due to the lack of coating, which seriously affects the appearance quality of the sand mould and the casting; 3. The coating on the brush will drip on the ground, causing waste; 4. Because the coating is flammable, the coating dripping on the ground may be ignited at the same time when the coating on the surface of the sand mould is ignited, which has a great safety hazard.
