However, rubber and plastics are soft and lack durability, so if they are used for a long period of time, the letters, designs, etc. on the page will become deformed or worn out, making them unusable. Another drawback is that when exposed to high temperatures or pressure applied for a long period of time, the pores in the printing surface collapse and the ink does not bleed out smoothly.

Fill with easily water-soluble salt powder within the range of 10-150μ. The mold at this time does not necessarily need to be made of metal, but may be made of a fireproof material having the required strength, such as graphite. Further, as the shape of this type, any shape such as a prismatic shape, a cylindrical shape, a truncated pyramid shape, a truncated cone shape, a cubic shape, etc. can be selected.

因となる。 Next, the easily water-soluble salt powder to be filled into this mold is
There is no particular restriction as long as it is a non-thermally decomposable metal salt powder that can be easily dissolved in room temperature or heated water.
Those with high melting points are advantageous. Examples of such easily water-soluble salts include stannous chloride, zinc chloride, cupric chloride, magnesium chloride, potassium chloride, sodium chloride, barium chloride, magnesium sulfate, potassium phosphate, and the like.
This easily water-soluble salt powder needs to have a particle size in the range of 10 to 150 microns. If the particle size of the powder is smaller than this, it will be difficult to form a porous structure with completely continuous pores, and the ink will not ooze out smoothly from the surface of the resulting printed material. On the other hand, if the particle size is too large, the strength of the resulting print will be insufficient, and a large amount of ink will ooze out, contaminating the stamped area.
この金型に易水溶性塩粉末を充填する場合、最
終的に得られる多孔質金属の気孔率が60〜80％程
度になるように充填するのが望ましい。このため

で選択するのがよい。 When filling this mold with easily water-soluble salt powder, it is desirable to fill the mold so that the porous metal finally obtained has a porosity of about 60 to 80%. For this purpose, the filling rate of the easily water-soluble salt powder is preferably selected in the range of 50 to 70%.

字部分には粒径10〜150μの粉末を充填し、イン
キ吸蔵部分にはさらに大きい粒径のもの、例えば
100〜1000μのものを充填することもできる。 When filling this mold with easily water-soluble salt powder, the printing area is filled with powder with a particle size of 10 to 150μ, and the ink storage area is filled with powder with a larger particle size, e.g.
It can also be filled with 100-1000μ.

が有利である。 Next, in the (b) step, the easily water-soluble salt powder is sintered, and the mold filled with the easily water-soluble salt powder is placed in a heating device such as an electric furnace as it is, and the temperature is 650 to 800°C in the case of sodium chloride. This is done by heating to. The time required for this sintering is usually 2 to 10
It takes about an hour. Through this sintering process, the powder particles, which were in point contact before sintering, now come into surface contact, and after molten metal is injected and easily water-soluble salts are washed away, almost completely continuous pores are formed. That will happen. At this time, the longer the heating time, the more the contact area ratio between each particle increases, but if the heating time is too long, a state where independent voids begin to form, a so-called oversintered state, will occur, and molten metal will be press-fitted in the subsequent process. This is not desirable because it makes it impossible to do so. In order to prevent this oversintered state from occurring, it is advantageous to control the porosity of the easily water-soluble salt sintered body within a range of 15 to 50%.
次いで、(ハ)工程においては、(ロ)工程で得た易水

要な処理であり、この予熱が不十分であると、品
質のよい多孔質金属とすることができない。 Next, in step (c), the easily water-soluble salt sintered body obtained in step (b) is preheated, and molten metal is press-fitted into the sintered body. This preheating is a necessary process to facilitate the press-in of molten metal and to obtain a printed body with homogeneous and completely continuous pores.If this preheating is insufficient, the porous metal may not be of good quality. Can not.
この予熱温度としては、溶融金属の凝固点より

As the molten metal in this case, any metal or alloy can be used as long as it has a melting point lower than that of the easily water-soluble salt. Examples of such materials include tin, lead, zinc, aluminum, iron, copper, silver, gold, and alloys thereof.
本発明においては、これらの金属又は合金を使
用するに当つて、その融点よりも高い融点をもつ
易水溶性塩を選択するように配慮する必要があ
る。 In the present invention, when using these metals or alloys, care must be taken to select an easily water-soluble salt having a melting point higher than the melting point of the metal or alloy.
この溶融金属の圧入圧力は、焼結体の空隙を流

秒ないし数分の範囲である。 The press-in pressure of the molten metal needs to be greater than the fluid resistance of the molten metal flowing through the pores of the sintered body, and usually a pressure of 30 kg/cm 2 or more is used. Further, the time required for this press-fitting varies depending on the size of the intended print body, but is usually in the range of several seconds to several minutes.

えば彫刻機がドリルなどを用いて行われる。 Next, in step (d), this composite is cut into a predetermined shape, and the required letters, designs, etc. are engraved on the surface. In this case, if a metal oxide film is formed on the surface, the hardness will increase and it will be difficult to engrave, so if necessary, this can be removed in advance by polishing or the like. The engraving is carried out using conventional means, such as an engraving machine or a drill.
