After-Sales capabilityThe stated business scope includes repair of general and special equipment, household-appliance repair, and installation services for general mechanical equipment. These activities support some service capability, but there is no explicit evidence regarding warranty terms, response times, spare-parts support, or actual after-sales performance.

Production capacityThe business scopes include manufacturing and sales of fans, power-facility equipment, dust-removal technology equipment, and mechanical parts, while the primary products are tunnel axial fans and tunnel ventilation duct cloth.
