本発明は、インクジエットノヅル等の微小ノヅルの製造
方法に関する事であり、特に電鋳法によるものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing micro nodules such as inkjet nozzles, particularly by electroforming.
従来よりノヅルは、いろいろな方法で作られており、電

その代表例を第1図及び第2図に示す。Representative examples are shown in FIGS. 1 and 2.

と同様に電鋳法によりてノヅルAを得る方法である。First, to explain Fig. 1, a hole is made at the tip of a mold 1 with a sharp tip and an insulating rod or vibrator 2 made of plastic or glass is inserted into the mold, and then the mold is molded using the usual electroforming method and peeled off. After pretreatment such as
After electrodepositing metal A such as nickel, it is peeled off from the mold to obtain nozzle A. The method shown in Figure 2 is a method in which an insulator is applied to the tip of the mold.
This method uses a mold in which the tip of the nozzle is immersed and the insulator 3 is formed, and the nozzle A is obtained by electroforming in the same manner as above.

事を要求されるが、上記従来の方法では、孔の周囲は、
逆に厚くなってしまう欠点がある。In the method shown in FIG. 1, the hole diameter can be guaranteed, but it is difficult to fit the mold 1 and the insulating rod 2 without a gap, and electrodeposition occurs even in this gap, often making it impossible to peel it off. Also, using this method to fake a nozzle with a pore diameter of several tens of microns,
Almost impossible in terms of mass production. Furthermore, the method shown in FIG. 2 has the drawback that it is difficult to uniformly apply the insulator, and the pore diameter changes due to the overhang of the electrodeposited insulator. Generally, when the hole diameter of the nozzle is small, the thickness of the plate at the nozzle exit is also required to be thin, but in the above conventional method, the area around the hole is
On the other hand, it has the disadvantage of becoming thicker.
本発明の方法は、型1は単に先のとがった単純な形状の

孔径の微小ノヅルを電鋳によって、製作する方法である
。In the method of the present invention, a mold 1 with a simple, pointed shape is used, and a minute nozzle with a thin plate at the nozzle outlet and a highly accurate hole diameter is manufactured by electroforming.

鋳では、バーテングラインが出来容易に分離する。First, referring to FIG. 3, electroforming is performed with a mold 1 having a sharp tip inserted into a soft metal substrate 4 under a constant pressure. At this time, since the electrodeposition B is also applied to the substrate 4, the area near the exit of the tip nozzle becomes thin. Electrodeposition A and electrodeposition B meet at an acute angle, so in electroforming, a bartending line is created and they are easily separated.

ある。To explain FIG. 4, a hard metal substrate 5 and a soft metal 4 are connected to each other.
By forming it to a thickness of
This is a method for adjusting the depth of penetration by adjusting the thickness of the soft metal 4, thereby making the hole diameter more accurate.
第5図はフォトファプリケージlン等により孔7をもっ

同様電鋳して作るものである。In FIG. 5, a metal plate 6 with a hole 7 is manufactured by photofabrication or the like, and the tip of the mold 1 is fitted into the hole and similarly electroformed.
尚第6図に示す様に、型1は、必ずしも完全に尖った形
でなくとも良く、先端に微小の平面8をもたしても良い
。As shown in FIG. 6, the mold 1 does not necessarily have to have a completely pointed shape, and may have a minute flat surface 8 at the tip.

A metal plate 6 with holes 7 was made. After crimping a mold 1 with a conical tip onto this, electroforming nickel A to a predetermined thickness, 1. When peeled from the metal plate 6 and the mold 1, a product having holes having the same diameter as the aforementioned holes was obtained.
