In the broad and profound Chinese culture, we are constantly looking for new presentation methods that can use historical thinking and modern technology to make innovative breakthroughs. In the thousands of years of Chinese culture, there are so many themes that can be worshiped and admired by future generations. It is difficult to imagine that from chopsticks to stamp, the correlation is very low, but as far as we are concerned, it is not that different. Big, there is still cultural connection. This time TIGT has officially moved into the second new cultural field, touching on the "seal culture" that combines calligraphy and sculpture, and officially launched the "TIGT-titanium metal stamp" that has been in preparation for a long time. Returning to the topic of the origin of stamp, the oldest carved characters in history include oracle bone inscriptions from the Yin Dynasty, bell and tripod inscriptions from the Zhou Dynasty, Stone from the Qin Dynasty, etc. Any characters carved on gold, copper, jade and other materials are generally called "goldstones". The seal is included in the "gold and stone". The origin of the seal is said to be the Shang Dynasty or the Yin Dynasty, but there is no conclusion yet. According to relics and historical records, it appeared at least during the Spring and Autumn Period and the Warring States Period. In the middle of the Warring States Period, it was widely used by the world. At first, it was only used as a voucher for commercial exchange of goods. After Qin Shihuang unified China, the scope of stamp expanded to legal objects proving the rights and interests of those in power. They were held by those in power as a tool to rule the people. During the Warring States Period, Su Qin, the famous prime minister who advocated unification, wore the seal of the Six Kingdoms. In recent years, unearthed cultural relics have pushed the history of stamp forward for hundreds of years, that is to say, stamp existed in the Zhou Dynasty. Most of the ancient seals handed down from ancient times come from the ruins of ancient cities, rivers and ancient tombs. Some were abandoned by the defeated in the war when they were in exile, and some were abandoned on the battlefield by those who died in the war. According to the practice at the time, all stamp captured or snatched on the battlefield must be handed over, and officials must also be handed over after their transfer or death. Take off the seal and ribbon and hand it in. There are many others, such as those with names attached to official positions, as well as auspicious language seals, Xiao-shaped seals, etc., which are generally objects buried in sacrifices, rather than real products. Tang Xuanzong has a rectangular seal with the word "Gongyuan". Although these two seals are not marked with identification, Tibetan characters, but it is of an identification nature, and it is the earliest identification of Tibetan seals. After the Song Dynasty, the content of appreciating Tibetan seals became richer, and the seal cutting and materials used were very exquisite. Secondly, the connoisseurs' seals can also be used to test the spread of ancient precious paintings and calligraphy. TIGT titanium pole stamp-titanium alloy version Before 1954, titanium metal was mostly used for special purposes, mainly for military purposes. The use of titanium metal for stamp engraving first appeared in Japan. A titanium stamp must be made exquisitely. In terms of process requirements, in addition to the requirements for the material of the seal body, the engraving method also has many differences from wood and wood. Jade techniques are of course different from metal seals such as Bronze. The stamp body is a solid columnar titanium metal. First of all, in addition to finding a suitable method for cutting the titanium metal raw material, we also need to consider how to polish the surface of the titanium metal. Only when everything is ready can we proceed. The next stage: engraving the stamp. When it comes to engraving titanium metal, for Taiwan's stamp industry, engraving masters have rarely been exposed to this material, and it is difficult to master the technology. And we need to find masters who are willing to cooperate and have the ability to engrave titanium seals to assist us, and is a difficult problem. In the early days, we used the techniques we were familiar with and used laser engraving to slowly cut the surface of the titanium metal layer by layer to form the concave and convex surfaces required for the stamp, thereby showing the depth of the font. But then some problems arose. The metal has been burned by laser for a long time, not to mention scorched black, the surroundings of the characters cannot be sharpened, and the edges of the stamped imprints cannot be inked, and the characters are also deformed. Therefore, we gave up using lasers to engrave prints because we cannot present beautiful and practical products. Stamp engraving is inherently a science. To make titanium stamp, a professional engraving master is indispensable. After several searches, the dust finally settled. Then we worked hard to try various tools and materials to complete the engraving of titanium stamp. After six months, it is finally available. Titanium stamp currently only provide one specification, a personal medal with a diameter of "18mm". The medal is generally used for account opening and financial-related liquid assets. The body of the medal is round, symbolizing "wealth is coming", so The specifications are more commonly used for financial purposes, so the round stamp is the single choice for titanium stamp. The operation procedure of the titanium alloy used this time is very cumbersome and difficult When the hardness of titanium alloy is greater than HB350, it is particularly difficult to cut. When it is less than HB300, it is easy to stick to the tool and is difficult to cut. However, the hardness of titanium alloy is only one aspect that makes it difficult to machine. The key lies in the comprehensive impact of the chemical, physical and mechanical properties of the titanium alloy itself on its machinability. Titanium alloy has the following cutting characteristics: (1) Small deformation coefficient: This is a remarkable feature of titanium alloy cutting, and the deformation coefficient is less than or close to 1. The distance of sliding friction of chips on the rake face is greatly increased, which accelerates tool wear. (2) High cutting temperature: Since the thermal conductivity of titanium alloy is very small (equivalent to only 1/5 to 1/7 of No. 45 steel), the contact length between the chip and the rake face is extremely short, and the heat generated during cutting is not easily transmitted. It is concentrated in a small range near the cutting zone and cutting edge, and the cutting temperature is very high. Under the same cutting conditions, the cutting temperature can be more than double that of cutting No. 45 steel. (3) The cutting force per unit area is large: the main cutting force is about 20% smaller than when cutting steel. Since the contact length between the chip and the rake face is extremely short, the cutting force per unit contact area is greatly increased, which can easily cause chipping. At the same time, due to the small elastic modulus of titanium alloy, it is prone to bending deformation under the action of radial force during processing, causing vibration, increasing tool wear and affecting the accuracy of parts. Therefore, it is required that the process system should have better rigidity. (4) The cold hardening phenomenon is serious: Due to the high chemical activity of titanium, at high cutting temperatures, it can easily absorb oxygen and nitrogen in the air to form a hard and brittle outer skin; at the same time, plastic deformation during the cutting process can also cause surface hardening. . The chilling phenomenon not only reduces the fatigue strength of parts, but also increases tool wear, which is a very important feature when cutting titanium alloys. (5) Tools are easy to wear: After the blank is processed by stamping, forging, hot rolling and other methods, a hard and brittle uneven skin is formed, which can easily cause chipping, making the removal of the hard skin the most difficult process in titanium alloy processing. In addition, due to the strong chemical affinity of titanium alloys to tool materials, tools are prone to adhesive wear under conditions of high cutting temperatures and large cutting forces per unit area. When turning titanium alloy, sometimes the wear of the rake face is even more serious than that of the flank face; when the feed rate f<0.1 mm/r, the wear mainly occurs on the flank face; when f>0.2 mm/r, the wear of the front face is even more serious than that of the flank face. There will be wear on the knife face; when using carbide tools for finishing and semi-finishing turning, the wear of the flank surface should be VBmax<0.4 mm. In milling processing, due to the low thermal conductivity of titanium alloy materials and the extremely short contact length between the chip and the rake face, the heat generated during cutting is not easily transmitted and is concentrated in the cutting deformation zone and a small range near the cutting edge. During machining, extremely high cutting temperature will be generated at the edge of the cutting edge, which will greatly shorten the tool life. For titanium alloys, as long as the tool strength and machine tool power allow, the cutting temperature is the key factor affecting tool life, not the cutting force. **Advantages of the TIGT Titanium Stamp** In addition to inheriting many advantages of titanium metal, The most important points are the following: **1. Hard texture:** The feel of the stamp is unmatched by that of ordinary wood. The handwriting is clear and durable, It will not be deformed due to long-term pressing and use. **2. Moisture proof and mildew proof:** Stamp are often contaminated with inkpad and other materials, Wooden stamp are prone to problems such as moisture, affect durability. **3. Will not oxidize and rust:** The ink pad remains or is contaminated with moisture. On stamps such as steel Bronze and copper stamps, There will be problems with rust and oxidation. Titanium stamp are easy to store and don't have this problem. **4.Easy to clean:** Seals are often stained with stamp, Wiping with toilet paper often leaves paper scraps stuck on the printed body. If the method of washing with water is not only troublesome but also afraid of damage to the print, Titanium stamp can be wiped with alcohol, burned, washed with water, etc. Way to remove ink pad oil stains without fear of damage. (PS. But fire will change the oxide layer on the surface of the stamp body. The thickness will cause the color to change! ) **5. No metal allergy problem:** A few people are allergic to metals. In particular, there are often hand sweat and oil stains on the stamp, Make skin more sensitive and uncomfortable, titanium imprint body is biocompatible High, and no allergic reactions have been documented in humans , can be used with confidence. **6. Diverse hair color printing:** They are all using the same TIGT titanium Tianqi products. Made with hair color technology, completely non-toxic, Don't worry about hurting your hands. **7. The price is lower than that in the Japanese market:** If the 18mm diameter titanium stamp with the same specification as TIGT, The engraving price in the Japanese market will fall to Between NTD.6,000 and NTD.10,100, The material is made of pure titanium and has no polishing or coloring effects. There is no titanium alloy version. It is also impossible to make such stable and smooth deep carvings. Not to mention font differences and difficulty in communication. **Stamp specifications** Material: Solid titanium alloy (90% titanium content) Size: diameter 18mm, length 59-60mm Condition: solid raw material Surface treatment: hand polishing + multiple voltage color forming technology
