Titanium forging is a manufacturing process that involves shaping titanium or titanium alloys using compressive forces to achieve desired shapes and properties. It is a widely used technique in industries where high strength, lightweight materials are required, such as aerospace, automotive, and medical.
During the titanium forging process, a solid billet or ingot of titanium is heated to a specific temperature to increase its malleability. It is then placed between two dies and subjected to compressive forces through mechanical or hydraulic presses. The application of pressure causes the titanium to deform and take on the shape of the dies, resulting in a forged part with improved mechanical properties.
One of the key advantages of titanium forging is the enhanced strength of the final product. The forging process aligns the grain structure of the titanium, resulting in a more uniform and refined microstructure. This leads to improved mechanical properties, including higher tensile and yield strength, as well as increased fatigue resistance.
Titanium forging also allows for precise control over the shape and dimensions of the final part. Complex geometries, such as turbine blades, aerospace components, and medical implants, can be achieved through forging, ensuring tight tolerances and excellent dimensional accuracy.

Recently, a massive cargo ship with a capacity of 23,000 tons was carefully launched from the dock in Ningbo, Zhejiang. This impressive vessel was constructed by Shishi, a well-known private shipping company, and is set to be named “Shishi Lion.†It marks the largest cargo ship ever built in Quanzhou so far. What makes this development even more remarkable is that the ship has successfully passed rigorous inspections conducted by the Fujian Classification Society’s branch, earning it a class certification. This means it is approved for both domestic and international trade routes.
According to reports, Shishi Shipping currently operates several vessels with a carrying capacity exceeding 10,000 tons, but most of them are not classified ships. Building a classified ship with a 23,000-ton capacity comes at a significantly higher cost—tens of millions more than constructing a non-classified vessel of similar size. A representative from the City Shipowners Association explained that Shishi's decision to invest in such a high-standard ship reflects strong confidence in the future of the shipping industry. It also shows that local shipbuilding companies are adopting more forward-thinking business strategies.
“The municipal government has always been supportive of maritime development,†the representative added. “In 2005, a series of policies were introduced to promote the industry, and their implementation has been effective. Although there have been some fluctuations in recent years, the overall situation remains stable. Especially over the past year, the maritime sector has seen significant growth.†In the second half of last year, freight rates hit a peak not seen in years. While they have slightly dropped after the Spring Festival, they remain at a high level. The booming market has led to increased contributions from the maritime industry to the local economy.
In 2007, Shishi-based shipping companies paid over 12 million yuan in taxes for the entire year—an increase of more than one million compared to 2006. The new 23,000-ton cargo ship will undergo a series of strict tests before its official launch. It is expected to begin operations as the "Shishi Lion" within the next two months. This milestone highlights not only the growing strength of Shishi’s shipping industry but also the broader momentum in China’s maritime sector.
