In April 1965, the First Ministry of Machinery Industry officially issued the "Procedures on the Intermediate Test Plan for Synthetic Diamonds" approved by the State Science and Technology Commission, requiring the establishment of artificial materials in the Abrasives Grinding Research Institute (hereinafter referred to as "Sanmao"). Diamond intermediate test base. The units participating in the intermediate test are the research institutes of the First Ministry of Machinery Industry: Zhengzhou Sanmao, Jinan Casting and Forging, and Shanghai Materials Research Institute. They are fully responsible for the synthesis process, raw material processing technology and product sorting process. And research on physical and chemical inspection methods; Jinan Casting and Forging Institute is responsible for the design and trial production of six-faced ultra-high pressure synthesis equipment, Hu Enliang of General Machinery Research Institute, and designed two sets of six 6×300 tons and 6×600 tons as early as 1963. According to the instructions of the Ministry of Machinery Industry, in June 1964, Hu Enliang handed over two sets of drawings to Jinan Casting and Forging, and made a technical basis for Jinan Casting and Forging; Shanghai Materials Research Institute was responsible for the hard Development of alloy anvil.
In August 1965 , under the close cooperation of Sanma Institute of Jinan Casting and Forging, the first 6×6MN DS-023 hinged six-sided anvil ultra-high pressure and high-temperature diamond synthesis device was produced in China. Sanguang Institute Wang Guangzu, Yu Zhengmin, Yu Zhichao Li Jinbao, Shao Dehou, Yan Juwu, and Kong Lingchun conducted synthetic diamond tests in Jinan forging and forging. November 5, 1965, at 6 × 6MN DS-023 type six-sided hinged first synthesis of a diamond, which is an important sign of success hinged six of the top diamond synthesis device trial with Chinese characteristics. After six months of testing repeatability synthesis of diamond synthesis process stabilized, on June 7, 1966, that six of the top synthesizing apparatus departure from Jinan, Zhengzhou three mill to reach the 10th.
July 3, 1966, voted man-made diamond synthesis intermediate test work. In the year of production of 10,000 carats of diamonds, in October 1966, the Ministry of Machinery Industry approved the construction of China's first synthetic diamond plant, the sixth grinding wheel factory, in the suburb of Guiyang, Guizhou Province, China. The complete process design and technical information provided by Sanmao was provided. And responsible for personnel training. This is the beginning of the industrial production of synthetic diamonds in China. The hinged six-sided diamond synthesis press has laid the foundation for the industrial production of synthetic diamond in China.
When Zhengzhou Sanmao built the national superhard materials and products engineering technology research center in 1996, the press was saved as an important cultural relic of China's superhard material industry in No. 121 Huashan Road. The Ministry of Machinery Industry is super hard on the country. At the acceptance of the Materials and Products Engineering Technology Research Center, Mr. Fan Hongcai, then the chief engineer of the Ministry of Machinery Industry, wrote the “ China's first six-sided top press †for the press .
The press was commissioned in 1965. It was retired in 1995 and put into operation for 30 years. It was synthesized about 1.5 million times and was named as a meritorious press.
