Precision Machining
CNC-controlled multi-axis machining centers operating to tolerances of ±0.002mm across all structural and powertrain components.
SOI Automotive Manufacturing sets the global standard for engineered excellence — from stamped steel to final assembly, every component reflects our uncompromising legacy.
Founded in 1987 in the heart of North Holland, SOI has grown from a precision machining workshop into one of Europe's most respected full-cycle automotive manufacturers. Our Haarlem facility spans over 140,000 m² of advanced production space.
From chassis architecture and powertrain integration to final quality validation, every stage of our process is executed with ISO-certified precision and a relentless commitment to innovation.
