preface:
2024 is the 75th anniversary of the founding of new china.
after 75 years of continuous progress, the town, as the most basic administrative and economic unit, has described the texture and background of high-quality development. although small towns are small, they are tens of thousands of administrative units covering 9.6 million square kilometers. they are windows showing the development and changes of the times, poetic connections between cities and villages, and important pivots to promote the integrated development of urban and rural areas. some have become global some of the "hidden champions" of basic necessities, food, housing and transportation are lighting up the dream voyage of chasing the stars and the sea.
enter "magic town" to see the high-quality development of a large country.
“diamonds are forever, one will last forever.” natural diamonds are very luxurious jewelry. but zhecheng, a small town with no mountains and few mines, relies on the secret of "growing" diamonds to bring cultivated diamonds into the homes of ordinary people. here, realizing "carat freedom" no longer seems far away.
diamond is also the common name for diamond. there is also a saying circulating in the industry: for the world’s diamonds, look to china, for chinese diamonds, look to henan, and for henan’s diamonds, look to zhecheng. zhecheng's annual output and export volume of diamond powder account for more than 90% of the national market share; its annual output of large single crystals and export volume of cultivated diamonds both account for 60% of the national market share.
from the “hometown of diamond powder” to the “city of diamonds”, zhecheng has transformed step by step and developed hard-core industries.

a diamond can grow up to 50 carats in an "artificial mine"
a diamond makes zhecheng shine in the world.
on october 19, 2020, the "china group standard for lab-grown diamonds" was reviewed and passed in zhecheng. it not only fills the gap in china's lab-grown diamond product standards, but is also the world's first lab-grown diamond product standard. in 2021, the global production of cultivated diamonds will be 9 million carats, and zhecheng will exclusively own 4 million carats, becoming the global base for the production of cultivated diamonds.
lab-grown diamond products
"as for the product of cultivated diamonds, we can now achieve mass production of 0.1-30 carats, and the laboratory can produce 50 carats." chen yanan, director of the project department of henan power diamond co., ltd., said.
in june 2023, at the jewelry expo held in las vegas, the united states, power diamond exhibited a 50-carat diamond product, which attracted world attention and became a shining business card for henan province's diamond product manufacturing industry to go overseas.
in fact, cultured diamonds are artificial diamonds that have reached gem quality, and their dazzling light also reflects the development history of zhecheng and even my country's superhard materials industry.
the "meritorious press" that witnesses the development of my country's superhard materials industry
in 1963, my country's first artificial diamond was born at the zhengzhou abrasives and grinding tools and grinding research institute (third grinding institute). in 1965, my country's first artificial diamond six-sided press was successfully developed. after this "meritorious press" came out, it was settled in zhengzhou no. 3 grinding institute. the third grinding institute is known as the "whampoa military academy" of china's superhard materials industry and has also sown the seeds for the development of the diamond industry in zhecheng.
polishing “the sharpest industrial teeth” from scratch
in the early 1980s, feng jinzhang, then a polycrystalline diamond research engineer at the third grinding institute, was invited to return to his hometown and participate in the establishment of the shaoyuan diamond factory, the first diamond factory in zhecheng. from here, the first batch of diamond technology backbones in zhecheng emerged, triggering a "fission" effect.
products of zhecheng county diamond tool factory
wang zhanxi was one of the first "crab eaters" that year. he founded the zhecheng county diamond tool factory in 1985 and has been operating it ever since. "i first started producing wire drawing dies, and started producing micro powder in 1990."
"throughout the 1980s and 1990s, every household seemed to be making micro-powder products. we at power diamond were actually the first to start by making micro-powder." chen yanan mentioned that zhecheng was first known as the "hometown of diamond micro-powder", which is also a benefit. here it is.
micropowder is a branch product under diamond. as a superhard material, diamond is widely used in precision manufacturing, construction stone, electronic information, aerospace and other fields. it is indispensable for processing and grinding various difficult materials, and is vividly known as the "industrial tooth".
with diamonds and the courage to take over the porcelain work, zhecheng's superhard materials industry has grown step by step. today, there are more than 120 diamond industry companies in zhecheng, and the entire chain is integrated into the upstream and downstream of diamond products. behind strengthening the industrial chain is the determination and long-term planning to develop the diamond industry. in 2006, an industrial park was established in zhecheng; in 2009, the industrial park was upgraded to an industrial cluster; in 2022, the construction of a diamond industrial park was launched.
wang chenchen and his father wang zhanxi
"after thirty or forty years, our diamond industry has grown from scratch, from small to large, and it has been accumulated bit by bit. it is inseparable from the joint efforts of the government, enterprises and other parties." wang chenchen is the daughter of wang zhanxi , she has taken over the baton of business management from her father.
"i studied international trade in college, and my father's wish is that i can better promote our products to the world." in late september, wang chenchen took the company's products to italy for an exhibition. as the second generation engaged in the diamond industry in zhecheng, she is contributing her own strength to the development of the industry.
technological innovation drives the use of "hard" power to show "innovative power"
"in the future, the application prospects of functionalization are very broad." chen yanan said that diamond is not only an "industrial tooth", but also has excellent properties in sound, light, electricity, magnetism, heat, etc., and is used in high-performance heat dissipation materials, diamond ultra-wide bandgap semiconductor materials, nanodiamond, optical window materials and other fields have great application potential.
diamond application prospects
to seize opportunities and create new advantages in the development of the diamond industry, technological innovation is indispensable. zhecheng strongly supports enterprises in technological innovation to enhance industrial competitiveness and influence.
currently, zhecheng owns 1,359 diamond core technology intellectual property rights and has won 1 national science and technology progress award and 4 provincial and ministerial science and technology progress awards. for example, the special special-shaped octahedral diamond developed and produced by power diamond for ultra-finishing processing of ic chips has independent intellectual property rights, breaking foreign monopolies, filling a number of domestic technology gaps, and has positive significance in solving the "stuck neck" of my country's chip processing.
invention patent certificate owned by a company in zhecheng
in addition, zhecheng has cultivated 21 high-tech enterprises in the diamond superhard industry, built 18 provincial engineering technology research centers, 1 academician workstation, and 1 provincial key laboratory.
technological innovation makes diamonds shine, and "hard-core" industries create the golden name of zhecheng as the "diamond capital". from a diamond to a chain, the sparkling diamond dream projects the development of china's superhard materials industry. extending and strengthening the chain, becoming more refined and stronger, this is always the direction zhecheng aims at. moving forward, zhecheng will continue to use its “hard” strength to show its “strength towards innovation”.
