SummarySigni Abrasive & Diamond Tools Co., Ltd., founded in 1996 in Shanghai, produces resin- and vitrified-bonded abrasives and super-hard diamond tools. It reports ISO 9001, ISO 14001, and ISO 14000 certifications, five production lines, 11–20 years of combined R&D engineer experience, and exports to a broad range of global markets. The supplier offers extensive customization and ODM services and reports OEM service for popular brands. However, it reports no overseas showrooms, agents or branches, or offline trade-show participation, and service procedures lack written records. No new products were reported during the past year, and no SDK is available. Quality assurance is stated, but the quality-control staff count is fewer than five. Financial information is present but is not sufficient here to establish a clear credibility assessment.
