The "Zizi" sound, blue lights flashing, and a steel disc with a diameter of 1.5 meters, embedded with diamond segments about 1 cm wide—this is just one of the thousands of products manufactured by Wuhan Wanbang Laser Diamond Tools Co., Ltd. ("Wuhan Wanbang"). The company has carved out a unique position in the global market with its advanced technology and high-quality diamond tools.
According to industry reports, China's annual export of synthetic diamonds exceeds 10 billion yuan, but most of these are raw materials with low value. However, Wuhan Wanbang has managed to break through this trend by leveraging its technological edge. In just three years, it surpassed long-established U.S. competitors and captured a significant share of the European and American markets.
**Costing $80, Selling for $600 – Technology Drives High Profits**
Last week, in the Wuhan Development Zone, a reporter visited this relatively unknown Chinese company that stands out as the only one in its industry with an international brand. DTT, short for "Diamond Tool Technology," is the brand name of Wuhan Wanbang’s diamond tools in the global market. The company produces four main product lines: laser-welded diamond saw blades, stone cutting blades, diamond grinding wheels, and diamond drill bits, all widely used in construction, stone processing, and decoration industries.
It is reported that currently, there are seven deep drilling projects in China, ranging from 5,000 to 10,000 meters deep, and four of them use diamond drill bits made by Wuhan Wanbang.
Ye Hongwei, a Ph.D. in powder metallurgy from Beijing University of Science and Technology, leads the technical team at Wuhan Wanbang. They developed the “pregnancy†diamond tool, which costs $80 to produce but sells for $600 in the U.S. market. In Wuhan’s production workshop, Ye Hongjun told reporters that a diamond saw blade with a diameter of 0.76 meters can achieve an 86% profit margin.
**Only 20 Square Meters of Warehouse – Almost No Inventory**
The U.S. is the largest and most demanding market for diamond tools globally. In 2009, Wuhan Wanbang established a new subsidiary in the U.S. to develop large-sized, high-power diamond saw blades. Each blade can cut through 7.6 kilometers of concrete, and after 12 years, this capability will increase to 12 kilometers—twice the efficiency of traditional U.S. tools.
Within just three years of entering the U.S. market, Wuhan Wanbang captured 5% of the market share, becoming the first Asian company to successfully penetrate the U.S. diamond tool sector.
During the visit, the reporter noticed that the finished goods warehouse is less than 20 square meters. This is because 90% of the products are exported directly, resulting in almost zero inventory.
Wuhan Wanbang’s sales have expanded beyond Europe and North America to include the Middle East, Australia, South America, and Russia. By 2012, the company’s annual sales reached 400 million yuan, showcasing its rapid growth and global influence.
