Wuxi JACK Technology Co., Ltd

Wuxi JACK (Wuxi JACK Technology / Wuxi AMASS Machinery)

Wuxi JACK Technology Co., Ltd (products); Wuxi AMASS Machinery Co., Ltd

Wuxi JACK Technology Co., Ltd designs, manufactures, and sells (with after-sales service) metal plate, pipe, and beam welding, cutting, and machining equipment. In March 2021, Wuxi AMASS Machinery Co., Ltd was set up specifically to handle overseas sales of JACK products and associated products, so the two names operate as a single supply chain.

The company states its engineering and management team members each have 20 to 30 years of professional experience in H-beam assembly machines, CNC pipe cutting machines, and related equipment. It reports an engineering staff of more than 10 experts who previously worked at Chinese state-owned companies, private companies, and a US company ranked in the top 100 of the Fortune Global 500. The company's Chief Designer is credited with having led the design of a large-diameter longitudinal seam submerged arc welding pipe production line built to American Petroleum Institute standard, replacing equipment previously imported from the US, and gained provincial-level recognition for design and development on that basis.

Wuxi JACK holds Quality Certification and patent certificates (shown as images on the homepage, specifics not confirmed). The company publishes detailed technical blog content covering real customer cases, including a business case on two ZHJ15-model H-beam welding machines, and a CNC-DX2040 steel box H-beam end-face milling machine delivered in 2025.
