Preferably, the thickness of the resin substrate 6 is 0.5-0.6mm, and the thickness of the resin substrate 6 is 0.5 mm. The shape is selected related to the material condition, when the paper fiber is longer and the quality is better, the hand feeling acuity of the particles can be properly improved, and the depth of the die is increased;

the molding pressure is effectively controlled, when the pressure is too high, the paper extrusion area is cut off, and the mold is quickly worn or broken; when the pressure is too low, sufficient crushing deformation cannot be generated, and the sharpness of the particles is insufficient.

The edges of the female mould must have a certain vertical depth, which is the key point for the definition of the granules, and when the mould is worn, it shows that the sharpness of the mould opening is reduced and it should be replaced in time.

Under the condition of white cardboard and proper mould pressing pressure, full braille particle effect can be obtained.
