On the morning of September 17, 2013, the opening ceremony and unveiling event of China Machinery Industry Group Seiko Co., Ltd. took place in the lecture hall of the Zhengzhou Abrasives Grinding Research Institute, located within the Zhengzhou High-tech Zone. Liu Dagong, Deputy General Manager of SINOMACH, represented the company at the event and delivered a speech expressing his warm congratulations on the establishment of the new subsidiary.
The occasion was attended by distinguished guests, officials, and industry partners. The event marked an important milestone for SINOMACH as it continued to expand its footprint and strengthen its presence in key industrial sectors.
SINOMACH, a leading state-owned enterprise in China’s machinery industry, has consistently demonstrated strong growth over the years. With a wide range of business operations spanning science, industry, trade, and gold, the group reported impressive financial results in 2012, achieving an operating revenue of 214.2 billion yuan and a profit of 8.6 billion yuan. This performance highlights its position as one of the top-performing enterprises in the sector.
Zhengzhou, known as a major city in the Central Plains region, plays a vital role in China’s industrial landscape. It is a key transportation hub and holds a strong position in industries such as textiles, machinery, and especially abrasive materials. The city is also home to significant resources in talent, education, research, and manufacturing, making it an ideal location for industrial development.
The collaboration between SINOMACH and Zhengzhou City, based on mutual benefit and shared goals, has led to strategic initiatives aimed at integrating grinding industry resources and building new material clusters. This partnership is expected to enhance the city’s industrial capabilities and support the growth of local enterprises.
The establishment of SINOMACH Seiko marks a significant step in the company's strategy to strengthen internal and external resource integration. By focusing on the “two major fields and three main businesses,†the company aims to optimize resource allocation and drive sustainable growth. This initiative not only supports the development of the abrasive industry but also contributes to the broader advancement of China’s machinery industry.
Looking ahead, SINOMACH aims to build a world-class enterprise by leveraging its strengths in R&D, manufacturing, and trade. The company seeks to enhance its global competitiveness while supporting the development of local industries in Zhengzhou. Through continuous innovation and strategic partnerships, SINOMACH is committed to becoming a leader in the global abrasives market.
Finally, I extend my sincere wishes for continued success and growth for SINOMACH and all its affiliated companies. May this new chapter bring even greater achievements and opportunities. I also express my gratitude to all the guests for their presence and support. Thank you.
