Pragmatism·Innovation·Excellence

Diamond is known as the "industrial tooth" and can almost "gnaw" on any material. Whether it is mechanical processing, geological exploration, metallurgy, or various material processing problems in the fields of aerospace, national defense, military industry, and electronic information, they can be easily solved in front of it. Henan ShiLi Diamond Products Co., Ltd. (referred to as Henan Shili) has been established for 19 years, continuously strengthening this niche industry and gradually growing into a leader in the industry.

The reporter learned that Henan ShiLi is a company that integrates the research and production of four major products: diamond dressing tools, grinding tools, cutting tools, and measuring tools. Its scale is above medium-sized in the same industry in China. Its products are mainly used in batch forming processing of automotive manufacturing, aviation industry, grinding and mold industry, precision screw and guide rail, non-ferrous metal precision processing, as well as bearing industry, textile machinery equipment, petroleum machinery, electric vehicles, cutting tools and other industries.

Although the superhard material industry is not large in scale, it belongs to the high value-added industry of 'specialization, refinement, novelty'. Since the shareholding reform in 2014, the company has continuously carried out technological innovation, and the products currently developed belong to a relatively complete category in China. "Wang Xiangjing, director of Henan Strength Office, said that the company has more than 200 specialized instruments and equipment, and the accuracy of many products has reached the international advanced level, which can replace imported products. At present, the annual production capacity of Henan Strength reaches one million pieces (sets).

Due to the good reputation of the product, more than 1000 enterprises have established cooperative relationships with Henan Strength, including state-owned enterprises, Sino foreign joint ventures, and wholly foreign-owned enterprises.

In a spacious and tidy workshop, dozens of devices are working. Technicians use computers to control products online, transforming them into widely used tools that can withstand tens of thousands of grinding cycles in high temperatures.

We also have the only three imported professional equipment in China - a five axis linkage CNC diamond roller tool grinder. It can be applied to industries that require particularly high precision, such as the field of aircraft engine blades. "Wang Xiangjing proudly said that with these three devices, online measurement and monitoring can be achieved, and processing efficiency has been doubled.

Henan ShiLi has invested over 10% of its sales revenue in research and development in recent years. In 2012, Henan ShiLi established the Diamond Cutting Tool Engineering Technology Research Center. In 2017, it was approved to build a provincial-level engineering research center and passed the acceptance inspection in early 2019. In recent years, Henan ShiLi has successively developed new products such as diamond aviation engine blade rollers and imported machine tool grinding machine specialized rollers. Among them, the diamond dressing roller was recognized as a 2016 independent innovation product by Henan Province. The diamond surface forming unit project has been included in the first batch of "Robot" Ten Hundred Thousand Demonstration Application Doubling Project in Henan Province in 2019. The company has also undertaken national Torch Plan industrial demonstration projects and has been rated as an innovative enterprise in Henan Province and a national level technology-based small and medium-sized enterprise.

As the technology leader of the company's R&D center, Xiao Yongjun, the general manager of Henan Strength, has been dealing with diamonds for nearly 30 years. He led technicians to devote themselves to scientific research and obtained multiple national patents. In the past three years, he has transformed nearly 30 scientific and technological achievements, obtained 32 utility model patents and 10 invention patents.

For many years, Henan Strength has maintained the good tradition of teachers leading apprentices and passing down skills from generation to generation. Xiao Yongjun imparted all the skills and professional knowledge he had mastered, cultivating a large number of technical backbones.

During the entrepreneurial process, I did practical things within my ability to revitalize the national industry. This is what I consider the most proud thing, "said Xiao Yongjun. One thing that left a particularly deep impression was that many years ago, the company undertook the task of developing diamond milling cutters for the cooling system of China's first aircraft carrier, and independently developed them for a full seven months. The scene of him shuttling back and forth between Luohe and Harbin for experiments is still vivid in my memory.

The reason why the company has developed so quickly is due to two aspects, one is innovation, and the other is the government's support for the enterprise in terms of policies and funds. When it comes to the future development of Henan Shili, Xiao Yongjun is full of confidence. He will continue to carry forward the spirit of craftsmanship and explore new fields.
