From an ordinary cutting workshop a few years ago to today's superhard material grinding, composite molding and laser cutting, Harbin Haimingrun Superhard Materials Co., Ltd. located in Niujia Industrial Park has realized the industrialization of “diamond composite sheetâ€. It is estimated that the capacity of its "diamond composite sheet" will increase from the current 100,000 to 2 million in three to five years, and it will become one of the largest diamond composite production bases in China.
With the development of geological exploration and mining, the performance of geological drilling tools has also been continuously improved. More than 10 years ago, Shenzhen Haimingrun Industrial Co., Ltd. was involved in the research and development of new materials for geological drilling tools. It focused on the synthesis and precision machining of diamond composite sheets for oil and gas drilling and quickly became the industry leader. At present, the company's diamond composite sheet for oil and gas drilling has reached a production scale of one million pieces, accounting for more than 50% of the domestic market, and exported to the mining industry powers such as the United Kingdom, the United States and Russia.
The reporter saw in the factory of Harbin Haimingrun that six “six-sided top presses†were half-lying in the ground. The computer controller showed that the temperature inside the press had reached more than 1400 degrees Celsius and the pressure was 60,000 atmospheres. According to the person in charge of the company, oil and gas drilling faces complex geological rock formations and must be drilled through super hard drill bits. At present, diamond drill bits with hardness much greater than boron carbide have become the industry's first choice, and it is not easy to put diamond on the drill bit. On the basis of introducing and absorbing the advanced technology of the United States, Haimingrun further researches and develops and innovates, and integrates the diamond powder with cobalt-nickel alloy materials through ultra-high temperature and high pressure, so that the diamond particles are directly bonded to the skeleton of cobalt-nickel alloy materials. This kind of diamond composite sheet has the super-rigid performance of the “rigid and soft†that the drill must have.
According to reports, Shenzhen Haiming Run established Harbin Haiming Run Branch in Niujia Industrial Park five years ago. The first-stage cutting workshop has 200 digital laser cutting machines. With the market demand and product structure adjustment, it was decided last year to build a super-hard material industrial park in Niujia, and transfer all its diamond composite sheet production and processing business to the cattle home. Before the end of last year, six “six-sided top presses†were put into production, marking that Harbin Haimingrun has realized the industrial production of diamond composite sheets. According to the design, in the next few years, Harbin Haimingrun will build 40 sets of “six-sided top pressesâ€, and produce 2 million pieces of diamond composite sheets annually, becoming one of the largest diamond composite sheet production bases in China, achieving sales revenue of nearly 600 million yuan. .
