Fountain pens were invented by Waterman in America in 1880. Various metals and plastics are used to make them. The most important part is the nib. For the nib, an alloy of pure gold, silver and copper is used. Scrap metal remaining after nibs have been stamped out is also used. Raw materials and scrap are put into a furnace. At this time, molten alloy at a temperature of 1000°C… … is poured into the mold. It is removed from the mold and quenched in water. The finished alloy is extruded using rollers. Gradually the roller gap is reduced, and it gets longer. It is reduced to a thickness of 0.5mm The shape of the nib is stamped out For the tip of the pen, the pen point, a different alloy is used. The pen point is a 1mm ball of extremely hard metal. The raw materials are osmium and iridium Osmium (chemical symbol Os) Iridium (chemical symbol Ir) An equal mixture of the raw materials is heaped on a little spoon. It is skimmed off using a roller… and uniform amounts are placed on a copper plate. It is instantly melted using an electric arc at more than 3000°C… and forms a ball due to surface tension. It is heated once more with the electric arc to perfect the sphere. The tipping is electric welded to the nib. The hardness of the tipping prevents wear. The imprint of the maker’s mark and the breather hole are stamped out together. Putting the curve in the nib. The nib is slit using a grinding wheel. The ink passes through this slit. The gap in the nib gradually narrows. Before processing. After processing. On the back of the nib, the feed is attached. Nib and feed. The role of the feed is to transmit ink to the nib. Feeds are mainly made of plastic. The raw materials are pressed into the mold. The middle channel is the ink channel. If the feed is dipped in ink, it flows in due to the capillary effect. When a fountain pen writes a character on paper, the ink flows into the gaps between the fibres. The barrel and cap and lots of other parts are made of plastic. Part of the cap. The metal part is put in the mold first… and the cap is molded and inlaid at the same time. Even though an adhesive is not used, the metal part wil not come off. The fountain pen is assembled. The cap is assembled. The detail parts are assembled by hand. The nib and feed are inserted into the section. Each pen is checked as it is assembled. The tip is finished by grinding on fine sandpaper to give a smooth writing feel. The finish is checked with a loupe. The final check for damage is performed during final assembly. And in this way the fountain pen can be delivered to us.
