What Haimingrun Co., Ltd. does

Haimingrun Co., Ltd. (深圳市海明润超硬材料股份有限公司) is a Shenzhen-headquartered Chinese manufacturer of superhard composite materials, founded in 2000 and publicly listed on China's National Equities Exchange and Quotations (NEEQ) under stock code 874930 since October 22, 2025. The company specializes in ultra-high temperature and ultra-high pressure (UHTHP) synthesis of polycrystalline diamond (PCD) composite sheets, polycrystalline cubic boron nitride (PCBN) materials, and related diamond tooling products used in oil and gas drilling, precision machining, and mining applications.

The company operates three core product divisions: (1) Oil and Gas Drilling — diamond composite sheets and PDC drill bit cutters serving oil service companies, with PDC products having reportedly broken the monopoly of European and American suppliers in high-end applications; (2) Precision Machining — PCBN materials, PCD composite sheets, and monolithic PCD cutting tool rods for hardened steel, carbon fiber, graphite, glass, and ceramic machining in aerospace, automotive, and 3C electronics sectors; (3) Mining — diamond drill bits and tools for geological exploration, coalbed methane extraction, and road milling. Manufacturing is anchored at the Zhongshan production base (capacity: 2 million pieces/year) with an R&D Center in Shenzhen and a multi-disciplinary team including PhDs and senior engineers collaborating with universities.

Haimingrun generates revenue through direct B2B sales of industrial materials under the Haimingrun brand, using a quote-based pricing model for bulk industrial buyers, with dedicated sales divisions per business line. Distribution is conducted through wholly-owned subsidiaries (HAI MING RUN INC. in Houston for North America; Perth service center for Asia-Pacific) and direct sales teams in China, with separate product-specific brand websites for each division. The company sells in 25+ countries and has been recognized as a national-level 'Little Giant' (Specialized, Refined, and Novel) Enterprise and High-Tech Enterprise, holding 61 authorized IP rights including 44 patents.

Emerging players

• Zhengzhou New Century Superhard Materials: Chinese manufacturer of PCD, PCBN, and diamond tools for drilling and machining applications. A regional Chinese competitor with overlapping product portfolio but smaller scale than Haimingrun.

Direct peers

• SF Diamond (四方达): SF Diamond is a Chinese publicly listed manufacturer of PCD and PCBN composite materials for drilling and cutting tools. Direct domestic competitor in the same Chinese superhard materials market Haimingrun serves.
• Zhongnan Diamond / Huanghe Whirlwind (黄河旋风): Huanghe Whirlwind is one of China's largest producers of synthetic diamond and superhard materials including PCD/PCBN. Comparable as a fellow Chinese superhard materials manufacturer with overlapping product lines and customer base.
• ILJIN Diamond: ILJIN Diamond is a Korean manufacturer of superhard materials including PCD and PCBN, serving drilling and cutting tool applications. Competes directly with Haimingrun across oil/gas drilling, precision machining, and mining segments.
• Element Six (De Beers): Element Six is the global leader in synthetic diamond and superhard materials, manufacturing PCD, PCBN, and polycrystalline diamond products for oil/gas drilling, precision machining, and mining. It is the primary competitor Haimingrun is attempting to displace in the Chinese market.
• US Synthetic Corporation: US Synthetic is a leading manufacturer of polycrystalline diamond (PDC) cutters used in oil and gas drill bits and mining. Highly comparable to Haimingrun's diamond composite sheet (PDC) product line with similar end markets and customer base.

Broad incumbents

• Sandvik (Mining and Rock Solutions / Machining Solutions): Sandvik is a Swedish engineering giant offering drilling tools for mining and rock excavation, as well as metal cutting tools. While not focused on superhard materials specifically, it competes with Haimingrun's mining drill bits and cutting tool materials as part of a broader portfolio.
• Kennametal: Kennametal is a global manufacturer of metal cutting tools and wear-resistant solutions, including tungsten carbide and PCD/PCBN-based tooling. Indirectly competes with Haimingrun's precision machining cutting tool materials via its tooling business.
• Sumitomo Electric Hardmetal: Sumitomo Electric Hardmetal is a Japanese manufacturer of cutting tools and wear parts including CBN and diamond-based materials. Comparable to Haimingrun's PCBN and PCD cutting tool materials for precision machining applications.
• Mitsubishi Materials (Cutting Tools): Mitsubishi Materials is a major Japanese manufacturer of carbide and superhard cutting tools, including PCD and PCBN tooling. Comparable to Haimingrun's precision machining business as another established global player in metal cutting tooling.
