Promax Engineering

What Promax Engineering does

Promax Engineering, LLC is a privately held, Michigan-based industrial sourcing and manufacturing intermediary founded in 2003 by Jun Zheng. The company supplies a broad range of metal components and assemblies — aluminum extrusions, die/gravity/investment castings, cold forming, forging, powder metal, stamping, machined parts, and full product assemblies — to North American customers in the automotive, appliance, and special vehicle industries. Its primary credential is ISO/TS 16949 automotive quality certification, supplemented by ISO 9001 certification achieved on February 24, 2006.

The company's operating model is dual-shore: a small North American headquarters team in Westland, MI handles engineering, quality assurance, program management, and logistics for customer-facing program launches, while production is executed at a manufacturing plant in Kunshan/Changzhou, China, supplemented by specialized Chinese partners. This structure allows Promax to offer cost-competitive Asian manufacturing with local program management support — a model explicitly marketed through its corporate website and a customer logo roster that includes ABB and approximately 11 other enterprise clients.

Promax generates revenue through direct B2B hardware sales of manufactured components and assembled products on a quote-based pricing model tailored to customer specifications and order volumes. The GTM motion is enterprise field sales targeting OEM and Tier 1 buyers. The company is independently owned, has no disclosed institutional investors, has not raised outside funding, and has no disclosed M&A or partnership activity in the source material. The most recent publicly documented product expansion was the addition of a Deburring Machine line in April 2017.
