Research and Development
We have more than 40 R&D personnel, of which 1 doctor, 8 masters and 35 bachelors. Our average annual expenditure invested in the R&D is 5 million. After years' preparation, research and development, we made breakthrough in terms of structural design, technical study, performance improvement, etc. in 2011. Consequently, we finally determined to declare more than 20 patents after several meetings related to the Intellectual Property Management in the latter half of the year 2011.
At the same time, the pilot test of our new cemented carbide products transformed from our patent achievement was carried out comprehensively. The trial production of floating bearing of drilling bits for mining and the improvement of the drilling bits with double containments both acquired periodic success.
Since 2010, we have been unremittingly exploring innovative mode of research, development and service. On the two aspects of the heat treatment and welding, we signed the Industry-University-Research Cooperation Agreement with the College of Material and Metallurgy of Wuhan University of Science and Technology. As for the issues of the piston of the DTH hammer and the heat treatment to DTH drill bits, we actively contacted experts from colleges and universities and signed cooperation agreement. In other words, we fully involve powers from society to effectively solve our problems and achieve win-win situation.
Meanwhile, we also introduce the international mode of service, work out the Mining Technology and Service Manual and allocate the wind pressure tester. Therefore, we are progressively providing professional and standard service for mining and increasing our service level domestically and internationally.
