Fetal loading brush bar
The eight manufacturing processes of fetal writing brush are summarized as follows:
1, pen material: mainly classify fetal hair according to length, thickness, color and presence or absence of front part.
2. Water basin: also known as hydraulic engineering. The pen maker tidies up the fetal hair soaked in the basin, and removes foreign hair, fluff and hairlessness. It is not suitable for writing, and it is arranged as a semi-finished pen tip. 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.
4. Puton: The process of choosing a 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. Fitting: It includes two parts: first, fitting the pen tip, that is, digging the selected pen tube and installing 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, blessing words, etc. on the pen.
