SummaryAnhui Wannan Electric Machine Co., Ltd. is a China-based limited company established in 1995, with 1,149 employees and a business scope covering motors, generators, pumps, electronic instruments, mechanical processing, and mold manufacturing. It demonstrates established quality and product certification credentials, including ISO9001, ISO14001, ISO18000, TS16949, CE, CCC, CECP, NEMA-related safety and energy certification, and DOE recognition. The supplier supports flexible customization, ODM, OEM for popular brands, documented R&D activities, standardized finished-product inspection, and production-related technical support. It has inventory capacity, export experience of 19 years, and exports comprising 31%–40% of total sales. However, it has no valid manufacturing-capacity contract with associated subcontractors, no overseas warehouse, showroom, agent, branch, or offline trade-show participation, and no SDK availability. Financial records are identified for 2021–2023, but no financial results are...

Supplier typeThe supplier is identified as a combined-type limited company based in Anhui, China, established in 1995. Its stated scope covers manufacturing and sales of motors, generators, chemical pumps, electronic instruments, mechanical products, and molds, indicating a broad manufacturing-oriented business profile.

CertificationsThe supplier reports ISO9001 certification since 1996, ISO14001 and ISO18000 since 2005, and TS16949 since 2015. Its IE2 and IE3 motors also hold CE, CCC, and CECP certifications, while NEMA motors have safety and energy certification and DOE recognition, providing explicit evidence of substantial quality, environmental, and product-compliance credentials.

After-Sales capabilityTechnology engineers provide technical support for production and after-sales service, and the supplier has inventory capacity, written service-capability procedures, and service quotation terms including FOB, CIF, CFR, and EXW. However, it has no overseas warehouse, showroom, agents, branches, or overseas service countries, so its documented support exists but its overseas service infrastructure is limited.

R&D capabilityThe supplier confirms customer requirements, designs new products, provides technical support, and maintains design input, output, review, verification, and validation documents for audit. It also provides ODM services, but has no available SDK, so the evidence supports product-development capability while not demonstrating SDK-based innovation support.

Production capacityThe supplier has a broad manufacturing scope, 1,149 employees, inventory capacity, standardized finished-product inspection instructions, written service-capability procedures with records, and a stated average lead time of within 15 workdays off-season and one month during peak season. A deficiency is explicitly present because the factory and associated subcontractors lack a valid manufacturing-capacity contract.

Customization capabilityThe supplier explicitly offers flexible customization, ODM services, and new-product design based on customer requests. R&D documentation covering design inputs, outputs, reviews, verification, and validation further supports a structured customization and development process.
