Supplier typeThe supplier is explicitly identified as a trading company and limited company, established in 2016 in Shanxi, China, with 10 employees and no stated larger-company affiliation. Its listed activities include manufacturing and selling fans, processing and selling mechanical parts, equipment repair, and installation services, indicating a trading-led business with some stated production and service activities.
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.
R&D capabilityThe supplier states that it launched new products during the past year, providing direct evidence of some product-development activity. However, it explicitly has no available SDK, and no further R&D resources, personnel, patents, or technical-development evidence are provided.
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.
