AI-Powered supplier vetting

SummaryHangzhou Hongtong Wire&Cable Co., Ltd. is a China-based limited manufacturing company established in 2004, with 88 employees and two major production facilities. It specializes in enameled magnet wire and related winding-system products, including applications in new energy vehicles, medical equipment, and 5G communications. The supplier reports IATF16949 and ISO9001 certifications, plus UL, RoHS, and REACH compliance. Production and quality-control indicators include expanded capacity, 21–30 quality-control staff, and an SGS audit record valid from March 5, 2025 to March 4, 2026. Its 2023 new-energy wire division and composite insulated wire development indicate some innovation activity. However, outsourcing procedures, contracts, inventory services, overseas warehousing, showroom services, R&D/ODM/OEM/SDK capabilities, Fortune 500 collaboration, raw-material traceability, and customer cases are not sufficiently documented. Financial information is excluded.

Supplier typeThe supplier is identified as a limited company and factory based in Hangzhou, Zhejiang, China, with 88 employees. It has specialized in enameled magnet wire manufacturing since 2004 and operates two major production facilities, indicating a direct manufacturing profile rather than a purely trading business.

CertificationsThe supplier reports IATF16949 automotive-grade certification, ISO9001 quality-management certification, UL certification, and RoHS and REACH compliance. An SGS audit record is also provided with validity from March 5, 2025 to March 4, 2026, although the supplied audit result is represented only by the value "0" and is not explained.

R&D capabilityInnovation evidence includes a dedicated New Energy Wire Business Division established in 2023, composite insulated wire development, and three years of total R&D engineer experience as recorded in the data. However, new-product output, ODM capability, SDK availability, and broader R&D indicators remain unknown.

Production capacityThe supplier has manufactured enameled magnet wire since 2004, expanded production capacity, operates two major facilities, and employs 88 people, with 21–30 quality-control staff. Its primary products are enameled round copper wire and magnet wire, supporting a conclusion of established production capability.

Product Q&A

Q:How to optimize wire selection for high-frequency transformers?

For skin effect, use Litz wire constructions to reduce AC losses >85% @100kHz. For dielectric loss, use polyesterimide coating to minimize capacitance drift. For process efficiency, use self-bonding wires to eliminate the varnish process. Contact us for application-specific simulation reports.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 500 kg.

Q:What is the average lead time for delivery?

The average lead time is within 15 workdays for both peak season and off-season.

Q:What payment terms do you accept?

We accept LC, T/T, D/P, Western Union, Small-amount payment, and PayPal.

Q:Is customization available for this product?

Yes, customization is available for wire diameter, structure, product model, and thermal class. We offer customization from samples, designs, full customization, minor customization, and flexible customization.
