Hansong adds U.S., Nanjing and Vietnam manufacturing capacity

Hansong Technology says it has expanded its global manufacturing and support network with a new U.S. facility, a new factory in Nanjing and an upgraded Vietnam site. The move is meant to boost OEM and EMS capacity, shorten support cycles and give customers more supply-chain flexibility.

Why it matters: - Hansong’s expansion adds production and support capacity across North America and Asia for brands that need more flexible manufacturing options. - The new footprint is aimed at higher-volume programs, complex electronics builds and supply-chain diversification. - The U.S. facility also moves some post-sale support and inventory functions closer to North American customers.

What happened: - Hansong Group expanded its global infrastructure with a new U.S. facility, an all-new factory in Nanjing and an upgraded production site in Vietnam. - The U.S. facility is at 27136 Burbank in Foothill Ranch, California, in Southern California’s logistics corridor near major freight routes and the Port of Long Beach. - Hansong says the facility can host product demonstrations, support third-party logistics, manage regional inventory and handle rework and customer support domestically. - The new Nanjing facility is described as the company’s most advanced production site to date and is built for high-complexity electronics programs. - The Vietnam facility has been comprehensively upgraded and continues to serve as a production hub for U.S. and European markets.

The details: - Hansong’s global network now includes four major manufacturing sites of purpose-built production space. - Fully integrated SMT lines operate in Nanjing and Vietnam for high-mix, high-volume output. - Acoustic testing labs and anechoic chambers are in the Nanjing and Denmark facilities for audio product validation. - Advanced automation is built into the production flow to improve consistency and reduce cycle times. - The Nanjing facility includes world-class certifications and cleanroom specifications. - Hansong says the network can support production runs from 100 pieces to millions. - The Vietnam site has vertically integrated manufacturing and warehouse space. - Vietnam supports both high-volume and low-volume, high-mix production. - The Vietnam operation focuses on wireless audio, smart home and connectivity devices. - The site maintains ISO 9001, RoHS and retailer compliance audits. - Full Country of Origin documentation is supported for U.S. customs compliance. - Hansong says the expanded OEM and EMS capacity includes more SMT, final assembly and packaging capacity. - Parallel production runs are available across Hansong’s China, Nanjing and Vietnam facilities. - Flexible minimum order quantities are available for scaling brands and established volume programs. - The company’s EMS offering covers BOM sourcing, PCBA, finished goods and fulfillment. - Dedicated program management teams are assigned to each partner account.

Between the lines: - The expansion tracks a broader industry push to reduce concentration in one geography and give customers more sourcing optionality. - The U.S. site appears designed to improve speed and service rather than replace offshore manufacturing. - The combination of China, Vietnam and U.S. support suggests Hansong is positioning itself for both scale and supply-chain resilience.

What's next: - Hansong is using the new footprint to support existing product lines and new launches at larger run rates. - The company is signaling that partner programs can now move across multiple sites depending on volume, complexity and origin requirements. - The expanded infrastructure is intended to support manufacturing programs at scale over the long term.

The bottom line: - Hansong is widening its global manufacturing reach to offer more capacity, faster support and more diversified production options for OEM and EMS customers.
