The manufacturing process of fetal writing brush is mainly summarized as follows:
① Pen materials: Mainly classified according to the length, thickness, color and presence or absence of front part of fetal hair. ② Water basin: also called 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.
③ Knotting: Also called tying number, the pen tip of the semi-finished product made in the basin is sent to this process for ligation. Then drop the melted rosin on the root of the pen, so that the bristles are not easy to fall off.
4 Puton: the process of selecting pen tube. In the selection, dry, moth-eaten, old-skinned and uneven-thickness pen tubes are eliminated one by one, and according to the specifications of various kinds of pens, pen tubes with consistent color, thickness and rod length are selected by classification. ⑤ Sleeve: It includes two parts: first, sleeve the pen tip, that is, dig the selected pen tube and put the ligated pen tip in it; The second is to prepare a pen cap for the installed pen. ⑥ Mosaic: It belongs to the process of decorating the pen container of a certain brush. This kind of pen generally uses ChristianRandPhillips Zhu, Cheng Yanzhu, ivory, mahogany, sandalwood and other materials as the main shaft of the pen holder, and then uses horn (later plexiglass) to make the pen tube more beautiful. There are two kinds of embedded heads (pen ends) and embedded tails (pen ends).
⑦ Pen selection: also known as pen repair. It is a key technical link in the manufacturing process of fetal writing brush. Pen selection is the final inspection and finishing process of the semi-finished tire brush formed in the previous process. It is necessary to remove the fetal hair that affects the internal and external quality, reshape the nib, and finally achieve the quality requirements of sharp, neat, round and healthy.
8 lettering: engrave the baby's name and date of birth on the pen tube.
In addition to the above main processes, there are degreasing (mainly by sun exposure), coloring, packaging and other processes.
Every process of fetal writing brush technology pays attention to fine operation and has high technical requirements. Examples are as follows:
Water basin: also called water 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.

Fitting: It includes two parts: First, fitting the pen tip, that is, digging a hole in the selected pen tube and installing the ligated pen tip in it; The second is to prepare a pen cap for the installed pen. The technical difficulty of locksmith lies in "turning", that is, digging holes in the pen tube. The size and depth of the hole are just right for the pen cover. Quality requirements: flat head and straight navel. Lake brush has the reputation of "not taking off a hair", and this process is the key. Fetal hair pen
Pen selection: also known as pen repair. It is a key technical link in the manufacturing process of fetal writing brush. Pen selection is the final inspection and finishing process of the semi-finished tire brush formed in the previous process. It is necessary to remove the fetal hair that affects the internal and external quality, reshape the nib, and finally achieve the quality requirements of sharp, neat, round and healthy. The process of choosing a pen generally goes through the process of note, pick and wipe. Choosing to wipe is the process of twisting and forming the nib. In jargon, it is called "choose three points and wipe seven points". The "light" and "white" required by Yang Hao's nib are reflected by the skill of wiping hands. Therefore, if you choose an apprentice in the pen industry, you must first practice the basic skills hard and practice the actual operation only if your gestures are accurate. The "roundness" and "collapse" of the pen tip will also be trimmed according to the feel of the pen picker.

Carving: Carving various fonts on the pen tube, such as the baby's name and date of birth. Seal cutting is also a kind of work with deep kung fu. Various strokes are called point, stroke (horizontal), vertical (vertical), left, press, kick (pick) and hook. The stroke order of seal cutting is not in writing order, but the same stroke of each word is carved at a time, and then another stroke is carved, which requires the seal cutter to be familiar with the structure of font strokes and the arrangement of characters. It is required that lettering be arranged evenly, such as "one incense" in the longitudinal direction, that is, the overall verticality of the characters cannot exceed the deviation of one incense. Font carving requires no spelling, no deviation, no leakage, no detachment and smooth strokes.
