In 2012, with the approval of Shandong Science and Technology Department and Shandong Changrun Diamond Co., Ltd. as the supporting unit, Changrun Diamond Company established the “Shandong Diamond and Product Engineering Technology Research Center”.

The Technology Center has a high-level R&D team consisting of doctors, masters and senior engineers, covering superhard materials and products, inorganic non-metallic materials, materials science and applications, material chemistry, polymer materials, composite materials, industrial automation. , mechanical design and manufacturing, industrial engineering, etc. The knowledge structure of talents is well matched, forming an elite team led by senior engineers and professional engineers, doctors and masters.

The technology center has an independent research and development site, with raw material laboratory, process laboratory, cutting laboratory and testing center. It has large high temperature and high pressure equipment, laser particle size distribution instrument, laser cutting machine, ultrasonic C scanner and topographic analyzer. 94 sets of precision instruments such as impact toughness tester and static pressure strength tester, and annual R&D investment accounts for more than 5% of the main business income. Adequate scientific research investment has provided a strong guarantee for the development of the center, so that the center's research and development level has maintained the technological superiority position of the domestic superhard materials industry.

The technology center combines its own technological research and development advantages, and is committed to the development of new products and the development of individual products for super-hard materials. It is committed to the forward-looking and basic research of raw and auxiliary materials and production processes, and is committed to high-efficiency and low-cost high-end. Research and construction of super-hard materials, with advanced information exchange and technology exchange platform, high-temperature and high-pressure development platform, advanced measurement and control technology platform. At the same time, focusing on the combination of production, education and research, we have established cooperative relationships with well-known domestic universities to achieve resource sharing and complementary advantages.

In recent years, the Technology Center has actively undertaken national, provincial and municipal scientific research projects, and has obtained a number of scientific and technological achievements with complete independent intellectual property rights, high technology content, high competitiveness, and popularization and application, and has formed an efficient research and development system. It has always maintained its technological advantages in the industry, and its research and development capabilities are at the forefront of the industry, making a significant contribution to the technological advancement of domestic superhard materials.

Raw material laboratory

The raw material laboratory integrates scientific research and production, and mainly tests and tests various raw materials used in diamond production, and researches, develops and produces new materials. High-quality, high-level research teams provide reliable material assurance for product quality.

Process laboratory


The process laboratory mainly researches and tests the production process, production process and new product technology of synthetic diamonds, etc. It has a relatively complete product research and development strength, advanced technology, and a professional scientific research team to provide quality for the products. Reliable guarantee.

Performance laboratory


The performance laboratory mainly conducts research and testing tests on the relationship between diamond products and diamond properties. By studying the different effects of different grades of diamonds in the use of diamond tools, it provides guiding reference for the production direction to meet the different levels of customer needs. .

Testing Center


The testing center is equipped with German automatic static pressure meter, German VDiamant high temperature furnace, Taiwan shape detector, laser particle distribution measuring instrument, C scanning detector and other advanced testing and testing equipment, which can carry out diamond crystal shape, cold impact toughness, Thermal shock toughness, static pressure strength, morphology analysis, bulk density, magnetic susceptibility, fine particle size, internal quality inspection of composite sheets, and other testing items. In addition to the inspection and quality control of the products before storage, the testing center is mainly responsible for tracking and testing the test results, and testing and grading the indicators of the daily production of the workshop, so as to promptly guide the workshop to grasp the test and production direction.
