What is the difference between HPHT and CVD diamonds?

Our rough diamonds are grown using the HPHT (High Pressure High Temperature) method, which mimics natural earth conditions to create diamonds with the same properties as natural ones.

AI-Powered supplier vetting

SummaryChenguang Machinery & Electric Equipment Co., Ltd. is a China-based limited trading company located in Changsha, Hunan, with its factory reported in Furong District. Its stated business covers development, production, and marketing of ultra-hard materials, including synthetic diamond, diamond drill bits, diamond cutting discs, and PDC cutters. The supplier reports ISO 9001 and GMP certifications, more than 10 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. It has self-operated import/export rights and has exported since 2010, with exports representing 31%–40% of total sales. Recent trade records show transactions involving synthetic diamonds and inserts with a buyer in Mexico, but the limited number of disclosed transactions does not establish a broad customer base. Evidence is insufficient to assess after-sales service, customization, and financial credibility.

Supplier typeThe supplier is identified as a trading company in Changsha and as both a trading company and manufacturer/factory in the company profile. Its stated business includes development, production, and marketing of ultra-hard materials, indicating a hybrid trading-and-manufacturing profile.

CertificationsThe supplier reports holding ISO 9001 and GMP management-system certifications. These certifications provide explicit evidence of formal quality and manufacturing management systems, although the slices do not provide certificate numbers, validity dates, or scope.

R&D capabilityThe company describes itself as specialized in the development of ultra-hard materials and reports 6–10 R&D engineers. Its product keywords include synthetic diamond and PDC cutters, supporting an identifiable R&D orientation, but no patents, new-product records, or technical performance data are provided.

Production capacityThe supplier states that it develops and produces ultra-hard materials, operates more than 10 production lines, and has annual output information listing 10,000,000 units for lab diamond and other products. The reported manufacturing infrastructure and output data explicitly support production capability, although the exact product allocation and capacity verification are not provided.

Client casesTrade records show three recent product categories—Inserts, Synthetic Diamond, and Synthetic Diamonds—with transactions involving Mexico and the same named buyer; the disclosed transaction counts are 2, 3, and 2 respectively. These records evidence some recent commercial activity, but the limited buyer and country coverage does not establish a broad or diversified customer portfolio.
