ッキ素材の表面を活性化させてピンホールの発生を防止
するための前処理を行っている。In general, the plating method involves spraying a coating film that imparts electrical conductivity onto the plating material, such as a spray liquid formed by mixing a paste silver lacquer and a butyl acetate solution, to impart electrical conductivity to the plating material. A pretreatment liquid made by mixing hydrochloric acid and stannous chloride in pure water is applied with a brush, etc., to activate the surface of the plating material and perform pretreatment to prevent pinholes from forming. ing.

キ素材表面上のメッキ層にピンホールが発生することを
防止するものである。The plating solution is formed by mixing a nickel sulfamino acid solution and boric acid, and then adding a small amount of lauryl sulfate (l) rum as a surface active additive, for example. This sodium lauryl sulfate prevents pinholes from forming in the plating layer on the surface of the plating material during plating.

素材の表面全体にメッキ層が付着するようにしている。After this, the plating material and the plating material gold are immersed in the plating solution stored in the plating solution tank, the plating solution is circulated, the cathode locker is activated, and the plating material is further moved in the plating solution to prevent the formation of pinholes. Plating material 100 between the plating material and the plating material while preventing
A current of 0.6 A with respect to ci is passed for 3 to 4 hours so that a plating layer adheres to the entire surface of the plating material.

メッキ素材の表面にはピンホールが発生する。After confirming that the plating layer has been deposited, change the current to 1 to 2 people per 100 d of plating material, continue plating so that the plating layer is smooth, finish it in the desired shape, and then remove the plating material. A mold 4 is formed by separating the plated layer and the plating layer. Note that if the current is made stronger than the above value, pinholes will occur on the surface of the plating material.

せる。In the above-mentioned plating method, the generation of pinholes in the mold 4 is prevented, but in this invention, the generation of pinholes is promoted by the method described below, and the pinholes are allowed to grow into the through holes 10. It is made porous. In other words, (Do not add any surface active additives such as sodium lauryl sulfate to the IJ plating solution.) (2) Do not spray a lacquer solution mixed with an insulating substance such as vinyl chloride onto the plating material before plating. Approximately 1
A layer of 5 μm is formed to reduce the electrical conductivity of the surface of the plated material.

ることができる。As shown in Figure 2.4, after the cutting of the sheet material 8 is completed, the suction pump 7 is activated 5 to suck air through the air collection pipe 6 and the air groove 5 to create a vacuum inside both 5.6. The sheet material S on the mold 4 is sucked through the through hole 10 and pressed against the upper surface of the mold 4. Since the sheet material 8 is heated and softened in advance, it deforms into a shape corresponding to the shape of the mold 4. Since the d through holes 10 are finely formed on the surface side of the mold 40, the shape of the through holes 10 is similar to that of the sheet material S.
It is never formed. In addition, if the distribution state of the through holes 10 in the mold 4 is changed and the through holes 10 are unevenly distributed in patterned parts such as grain carving υ, the sheet material S
Since it is strongly attracted, a clear pattern can be obtained on the sheet material S.
さらには、シート材料８の加工部分は均一に加熱された
