Since June of this year, on the SCJX Precision Titanium Alloy Technology Group's production line, 6 sets of machines have been running continuously to produce slender precision titanium alloy tubes. This kind of titanium alloy tube is called "titanium capillary tube", as the name suggests is only the size of our human blood vessels. It seems ordinary, but this kind of "titanium capillary" can save people's lives, such as the raw materials for organ bypass in the human body, including stents in blood vessel bypass and heart bypass. Panzhihua is known as "China's Vanadium and Titanium Capital" and is China's largest production base of vanadium and titanium products and China's only full-process titanium industry base. Recently, Hay Think employees walked into the provincial high-tech industrial park to visit the transformation and upgrading of Sichuan's titanium alloy industry.
More than 10 processes are required to produce a high-end "titanium capillary"
SCJX technical engineer Chen Long told us that from raw materials to products, the production process requires more than 10 procedures, and each link must be improved, which is related to the quality of the "titanium capillary". "According to the different requirements of customers, we produce precision titanium tubes of different specifications. The outer diameter of this ‘titanium capillary’ is only 0.5 mm and its wall thickness is only 0.02 mm."
In the company's product exhibition hall, Hay Think saw the "titanium capillary" used in medical operations, which looked only the size of an embroidery needle. According to reports, this "titanium capillary" is widely used in the medical field, such as the raw materials for organ bypass in the human body, including stents in blood vessel bypass and heart bypass.
According to the person in charge of the company, SCJX mainly provides non-ferrous metal materials and precision processed products based on titanium and titanium alloys. The products are widely used in petrochemical, medical equipment, aerospace, shipbuilding, seawater desalination and other fields. It is China's leading A high-end titanium alloy pipe production technology enterprise. At present, the first phase of production mainly produces various high-end micro-caliber "titanium capillary tubes". Currently, the construction of the second phase of the project is being planned. After completion, the full range of 0.8-8mm titanium pipes can be mass-produced in Panzhihua, with an annual output value of over 100 million yuan.
Titanium has a high melting point, low density, high alloy strength, and corrosion resistance. Modern medicine has also found that it has good compatibility with the human body. Therefore, special alloys are generally used in aircraft, ship, automobile manufacturing and various industrial equipment, and can also be used as artificial bone for medical treatment. Titanium has a wide range of applications in the medical field. Titanium is close to human bones and has good biocompatibility to human tissues without toxic side effects. In the past, "titanium capillary" production technology was monopolized by foreign companies, and China gradually broke the blockade through technology research and development.
At present, hundreds of metal parts such as femoral heads, hip joints, humerus, skulls, knee joints, elbow joints, shoulder joints, metacarpophalangeal joints, jaws, and vasodilators made of titanium and titanium alloys have been transplanted into the human body. A good result.
The first phase of the 100,000-meter titanium capillary production line project for medical and aviation industries invested and constructed by SCJX started production.
