Within the vast and profound Chinese culture, we continuously seek new avenues for innovation, drawing from historical perspectives and applying modern technology. Chinese culture, over thousands of years, offers an abundance of subjects worthy of reverence. It might seem a leap from chopsticks to seals, with little apparent connection, but for us, the transition is not so drastic; there remains a cultural linkage. With TIGT now officially entering a second cultural domain, touching upon the art of calligraphy and engraving – the "seal culture" – we are formally launching the long-prepared "TIGT Titanium Alloy Seal." Returning to the topic of the origin of seals, the earliest forms of carved text include the Oracle Bone Script of the Yin Dynasty, the Bronze inscriptions of the Zhou Dynasty, and the stone inscriptions of the Qin Dynasty. Texts carved on materials like metal, bronze, jade, and stone are collectively known as "Jin Shi" (metal and stone inscriptions), and seals are included within this category. The origin of the seal is attributed by some to the Shang Dynasty, or by others to the Yin Dynasty, with no definitive consensus yet. Based on archaeological finds and historical records, seals appeared at least by the Spring and Autumn and Warring States periods, becoming widely used by the mid-Warring States period. Initially, they served as proof of commercial exchange. After Qin Shi Huang unified China, the scope of seals expanded, becoming legal instruments to prove the rights of those in power, controlled by the ruling elite as tools for governance. During the Warring States period, the renowned minister Su Qin, who advocated for the "Vertical Alliance" strategy, famously wore the seals of the six states. In recent years, excavated artifacts have pushed back the history of seals by several hundred years, suggesting their existence even during the Zhou Dynasty. Surviving ancient seals are often found in ancient city ruins, riverbeds, and tombs. Some were abandoned by defeated warriors in flight, while others were left on the battlefield by those who perished. According to the customs of the time, seals captured or seized in battle had to be submitted. Officials were also required to relinquish their seals and their accompanying tassels upon changing positions or after death. Many others, such as those bearing official titles and surnames, auspicious phrases, or pictorial designs, were likely intended as burial items rather than actual usage seals. Emperor Xuanzong of Tang possessed a rectangular seal inscribed with "Gong Yuan," which, though not explicitly marked as a collector's seal, served an authentication purpose and represents one of the earliest known collector's seals. After the Song Dynasty, collector's seals became more diverse in content, with exquisite carving and materials, rivaling later developments and gaining favor among collectors. Furthermore, collector's seals provide valuable insights into the provenance of ancient treasured calligraphy and paintings. TIGT Titanium Pro Engraving - Titanium Alloy Version Prior to 1954, titanium was predominantly used for specialized purposes, primarily military. The earliest application of titanium for seal engraving appeared in Japan. Crafting a refined titanium seal requires not only high-quality material but also engraving techniques that differ significantly from those used for wood or jade, and certainly from metal seals made of copper or iron. The seal body is a solid cylindrical piece of titanium. Firstly, when cutting the raw titanium material, we not only find suitable methods but also consider how to polish the titanium surface. Once everything is prepared, we can proceed to the next stage: engraving the seal. Engraving titanium is a challenging task for most seal artisans in Taiwan, as they have had little experience with this material. Finding artisans willing to collaborate and possessing the expertise for titanium seal engraving presented another hurdle. Initially, we attempted laser engraving, using our familiar techniques to gradually ablate the titanium surface layer by layer, creating the necessary relief for the characters and their depth. However, this led to problems: prolonged laser exposure caused blackening, the edges of the characters lacked sharpness, and when stamped, the impression had blurred edges and distorted characters. Consequently, unable to produce a aesthetically pleasing and functional product, we abandoned laser engraving for the seal body. Seal engraving is an art form in itself, and for titanium seals, skilled artisans are indispensable. After much searching, we finally found suitable collaborators. The next step involved diligently experimenting with various tools and materials to achieve the titanium seal engraving. After six months of effort, the product was finally ready for market. Currently, titanium seals are offered in one specification: a personal round seal with a diameter of 18mm. Round seals are typically used for opening bank accounts and managing liquid assets. The circular shape of the seal symbolizes "wealth rolling in," making this size commonly used for financial purposes, hence the single round seal option for titanium seals. The titanium alloy used in this product involves a highly complex and challenging manufacturing process. Machining titanium alloy becomes particularly difficult when its hardness exceeds HB350. If the hardness is below HB300, it tends to cause "chatter" and is difficult to machine. However, hardness is only one aspect of machining difficulty; the key lies in the combined influence of titanium alloy's chemical, physical, and mechanical properties on its machinability. Titanium alloy exhibits the following machining characteristics: (1) Low strain ratio: This is a significant characteristic of titanium alloy machining, with a strain ratio less than or close to 1. The chip slides and rubs against the rake face over a greatly increased distance, accelerating tool wear. (2) High cutting temperature: Due to titanium alloy's low thermal conductivity (only about 1/5 to 1/7 that of 45# steel), the contact length between the chip and the rake face is extremely short. Heat generated during cutting is not easily dissipated, concentrating in a small area around the cutting zone and cutting edge, resulting in very high cutting temperatures. Under the same cutting conditions, the cutting temperature can be more than double that of cutting 45# steel. (3) High cutting force per unit area: The main cutting force is approximately 20% less than when cutting steel. However, due to the extremely short contact length between the chip and the rake face, the cutting force per unit contact area greatly increases, making it prone to chipping. Furthermore, because titanium alloy has a low elastic modulus, it easily deforms and vibrates under radial forces during machining, increasing tool wear and affecting part accuracy. Therefore, the process system requires good rigidity. (4) Severe "cold hardening" phenomenon: Due to titanium's high chemical reactivity, at high cutting temperatures, it readily absorbs oxygen and nitrogen from the air, forming a hard and brittle outer layer. Simultaneously, plastic deformation during the cutting process can lead to surface hardening. This "cold hardening" not only reduces the fatigue strength of the part but also exacerbates tool wear, making it a crucial characteristic when cutting titanium alloy. (5) Tool wear: The raw material, after being processed by stamping, forging, and hot rolling, forms a hard, brittle, and uneven outer skin, which is highly prone to chipping, making the removal of this hard skin one of the most difficult steps in titanium alloy processing. Additionally, due to titanium alloy's strong chemical affinity with tool materials, at high cutting temperatures and with high cutting forces per unit area, the tool easily experiences adhesion and wear. During turning of titanium alloy, wear on the rake face can sometimes be more severe than on the flank face. When feed rate f < 0.1 mm/r, wear primarily occurs on the flank face. When f > 0.2 mm/r, the rake face will show wear. When using cemented carbide tools for finishing and semi-finishing, flank wear VBmax < 0.4 mm is considered appropriate. In milling operations, due to titanium alloy's low thermal conductivity and the extremely short contact length between the chip and the rake face, heat generated during cutting is not easily dissipated and concentrates in a small area around the cutting deformation zone and cutting edge. This results in extremely high cutting temperatures at the cutting edge, significantly shortening tool life. For titanium alloy, within the limits of tool strength and machine power, cutting temperature is a key factor affecting tool life, rather than the magnitude of the cutting force. **Advantages of TIGT Titanium Seals:** In addition to inheriting the many benefits of titanium metal, the most important points are as follows: **1. High Hardness:** The feel when stamping is incomparable to ordinary wood, the characters are clear and durable, and will not deform from prolonged pressure and use. **2. Moisture and Mildew Resistant:** Seals often come into contact with ink pads and other materials. Wooden seals are prone to moisture damage, affecting their longevity. **3. No Oxidation or Rusting:** Ink residue or moisture contamination on steel or bronze seals can lead to rusting and oxidation. Titanium seals are easy to preserve and do not have this problem. **4. Easy to Clean:** Seals often get stained with ink pads. Wiping with tissue paper can leave paper fibers stuck to the seal. Cleaning with water is troublesome and risks damaging the seal. Titanium seals can be cleaned with alcohol, burned, or washed with water to remove ink and oil stains, without fear of damage. (PS. However, burning will alter the thickness of the oxide layer on the seal's surface, which will cause a color change!) **5. No Metal Allergy Issues:** A small number of people are allergic to metals, especially since seals often come into contact with sweat and oil from hands, which can cause discomfort to sensitive skin. Titanium seals have high biocompatibility and there are no documented cases of human allergic reactions to titanium, so they can be used with confidence. **6. Diverse Color-Treated Surfaces:** These are produced using the same color-treatment technology as TIGT Titanium Sky Chopsticks products, completely non-toxic. There's no need to worry about harming your hands. **7. Lower Price Compared to the Japanese Market:** If you compare titanium seals of the same specification (18mm diameter) as TIGT, the engraving prices in the Japanese market, when converted, range from NTD.6,000 to NTD.10,100. These are made of pure titanium, lack polishing or color treatment, do not offer titanium alloy versions, and cannot achieve such stable and smooth depth engraving. Furthermore, there are differences in fonts and communication difficulties. **Seal Specifications** Material: Solid Titanium Alloy (90% Titanium Content) Size: Diameter 18mm, Length 59-60mm Condition: Solid Raw Material Surface Treatment: Hand Polished + Multi-voltage Color Treatment Technology
