AI-Powered supplier vetting
SummaryThe supplier is presented as a diamond core bit, diamond blade, and TCT blade manufacturer that also provides OEM and ODM services. It reports exports to more than 27 countries and participation in the FEICON BATIMAT trade show, but has no overseas agents, branches, warehouse, or showroom. Its management certifications include ISO 9001, ISO 14001, ISO 45001:2018, and ISO 9001:2015, with CE product certification capability. Service procedures for complaints and corrective actions are documented and followed. However, the supplier lacks raw-material traceability, has no valid manufacturing contract with related subcontractors, and lacks outsourcing procedures and ongoing production quantity reconciliation. Innovation evidence is limited: no SDK, no new products in the past year, and no 3D software design service, although ODM and flexible customization are available. Financial evidence is insufficient because the provided entries contain years rather than financial results.
Supplier typeThe supplier is identified as a manufacturer of diamond core bits, diamond blades, TCT blades, and related drilling/cutting products. It provides OEM and ODM services, exports to more than 27 countries, and offers flexible customization, but has no overseas agents, branches, warehouse, or showroom.
CertificationsThe supplier reports ISO 14001, ISO 45001:2018, ISO 9001:2015, ISO 9001, and CE certification capability. These entries provide explicit evidence of multiple management-system certifications and CE-related product certification capability.
After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaint handling, and reports quality assurance in quality control. However, it lacks raw-material traceability and identification, which is a control weakness relevant to service resolution and product follow-up.
R&D capabilityThe supplier offers ODM and customization from designs, but explicitly has no available SDK, no 3D software design service, and no new product developed in the past year. The evidence indicates limited demonstrated innovation capability despite design-related service offerings.
Production capacityThe supplier reports two production lines and equipment including a saw blade press machine, shot blasting machine, and spray painting production line, with one-month average lead times in both peak and off-season. However, it lacks a valid manufacturing contract with related subcontractors, does not perform ongoing production quantity reconciliation, and has no outsourcing SOP.
Customization capabilityThe supplier explicitly provides OEM services for well-known brands, ODM services, customization from customer designs, and flexible customization. These statements directly support a positive assessment of customization capability.
