On March 6, 2013, General Manager Liu Jinchang of China Superhard Materials Network, together with Zhang Liang, a reporter from the website, walked into the Polycrystalline Diamond Division of the Science, Technology and Trade Department of Zhengzhou Abrasives Grinding Research Institute. Director Liu Yuzhou, Wang Nianzhou technician, Wang Jing engineer, and Guo Xingxing assistant engineer received warm reception. The two sides talked about the research and development, production and operation of polycrystalline diamond. 
Zhengzhou Abrasives Grinding Research Institute of Science, Technology and Trade is one of the earliest specializing in R&D and production of polycrystalline diamond products in China. It has more than 40 years of experience in research and development of polycrystalline diamond (PCD). The produced polycrystalline diamond (PCD) has higher strength, wear resistance, heat resistance, stable quality and high durability. Polycrystalline diamond and related products have an unparalleled alternative to traditional materials. The following polycrystalline diamond products are now available:
1. Silicon-based and cobalt-based polycrystalline diamond wire drawing core: (The size of diamond raw material ranges from W5-W50), widely used in high-tech fields such as copper clad steel, wire and cable, and aerospace. Product specifications are as follows (unit: mm):
Φ2×2;Φ4×1.5;Φ4×2;Φ5×2.5;Φ5×3;Φ6×4;Φ7×3.5;Φ8×4;Φ8×5;Φ8×6;Φ9×5;Φ10×5;
Φ10×6; Φ10×8; Φ12×6; Φ12×8; Φ14×8;
Φ14×10;Φ16×10;Φ16×12;Φ18×10;Φ18×12;Φ20×12;Φ22×14;Φ24×14;Φ26×14;Φ26×16;Φ28×16;Φ30×18;Φ30× 20 and so on.
2. Thermally stable polycrystalline diamond (TSP): widely used in petroleum, natural gas, geological drilling and mining, etc., with high temperature resistance and high strength. According to product strength, it can be divided into A: general quality class; B: high strength class; can be divided into cylinder according to product shape (product specifications such as Φ6.35×3.4; Φ8×4, etc.); cube (product specifications such as 3×3) ×3; 4 × 4 × 4, etc.): hexagonal body (product specifications such as 8 × 3.5); prism (product specifications such as 3 × 3; 5 × 5;); cube and other specifications.
3. Diamond sprays for the magnetic materials industry;
4. Polycrystalline diamond nozzles for the cutting and construction industries;
The above products can be customized according to user requirements. "Working with heart, cooperation and win-win" is the business philosophy adhered to by the Science, Technology and Trade Department of Zhengzhou Abrasives Grinding Research Institute. Through continuous innovation and perseverance, we will work together with customers and friends to create greater value.
