**Abstract**
From November 15 to 17, the 2nd China (Zhengzhou) International Abrasives and Grinding Exhibition, commonly known as the "China Sanmao Exhibition," took place at the Zhengzhou International Convention and Exhibition Center. This year’s event attracted nearly 40 equipment manufacturers and raw material suppliers from the superhard materials industry, showcasing the latest innovations and technologies in the field.
The exhibition has seen a steady increase in international recognition, with notable participation from global players such as Germany’s Feiyu and Malvern. Local companies also made strong showings, including Zhengzhou Jinhaiwei, Beijing Ninghua, Shanghai Maitong, Zhengzhou Machinery Research Institute, and Huijin Powder. Their exhibits drew significant attention, with many visitors placing orders on-site.
Among the highlights were Zhengzhou Jinhaiwei’s “automatic constant volume cold press,†Beijing Ninghua’s “super hard material EDM cutting machine,†and Huijin Powder’s new products like “pre-alloyed powder†and “reinforced iron powder.†These innovations received high praise from attendees, reinforcing the growing importance of this event in the global superhard materials sector.
Additionally, Zhengzhou Ruijun Electromechanical Co., Ltd. showcased its “six-sided diamond press double-acting reciprocating supercharger,†while Xi’an Yulang introduced its “thermosetting ceramic bond,†breaking the gap in domestic alternatives and capturing widespread interest.
This event not only provided a platform for industry leaders but also fostered valuable networking opportunities, highlighting the dynamic growth of the abrasives and grinding industry in China.
