The eight manufacturing processes of how to make tire brushes are summarized as follows: 1. Pen material: fetal hair is mainly classified according to length, thickness, color, front or back.
2. Water basin: also known as hydraulic engineering. The pen maker tidies up the fetal hair soaked in the basin and removes the miscellaneous hair, fluff and hairlessness. , not suitable for making pens, finishing into semi-finished nib. It is one of the most complicated and critical processes of fetal writing brush technology. There is also a process of wool degreasing in the basin method. Firstly, the root of fetal hair is degreased with limewater, while the degreasing of brush hair tip is carried out by "sun exposure and night dew" for a long time, so as not to damage the tip of fetal hair due to drastic changes, which is also the unique feature of fetal brush technology. 3, knot: also known as tying number, send the pen made of semi-finished products from the basin to this process for ligation. Then drop the melted rosin on the root of the pen, so that the bristles will not fall off easily.

There are two kinds of embedded heads (pen ends) and embedded tails (pen ends). 7, pen selection: also known as pen repair.
