Supplier typeThe supplier is identified as a factory and a limited company located in Kunshan, Suzhou, Jiangsu, China. It was established on March 10, 2016, and has 25 employees, indicating a relatively small manufacturing enterprise.

After-Sales capabilityThe supplier has written procedures and records for customer complaint handling, corrective and preventive actions, and service-capability assessment. However, it has no overseas warehouses, showrooms, agents or branches, has not participated in offline trade shows, and reports zero countries with overseas services.

It lists CNC lathe, machining center, and screening-machine capabilities, employs five quality inspectors, follows standardized finished-product inspection instructions, and reports lead times within 15 working days in both peak and off-season.
