Zi Machine President, Steve Zeldag

For over 30 years, Zi Machine has proven its dedication and craftsmanship in the machining trade. 

Zi Machine was founded in 1983 in the San Francisco Bay area of California. With almost no marketing or sales effort, the small company attracted constant work from several Tier 1 defense companies due to its expertise in machining critical missile components and discrete parts from refractory alloys.  Soon customers in the semiconductor, oil/gas and industrial valve industries developed long-term partnerships with Zi Machine. The work ethic, integrity, sense of accountability and demand for quality attracted many like minded individuals to the ZI Machine Team.Today, 23 employees at Zi Machine offer dedication and craftsmanship in the machining trade.
