Overview
About Van Hoof Groep
Who we are
Van Hoof Groep is a Dutch manufacturing group specialised in precision metalworking and the production of customer-specific components and assemblies. Our capabilities include CNC milling and turning, gear manufacturing, grinding, sheet metal processing, laser cutting, punching, bending, welding, assembly and quality inspection. By combining these disciplines within one organisation, we can supply both individual components and complete welded or assembled products. A key specialism is the production of customer-specific gears and transmission components, including spur gears, helical gears, internal gears, splines and related precision-machined parts. We support customers with manufacturability, material selection, heat treatment and inspection requirements. Van Hoof Groep supplies recurring small and medium-sized series to customers in sectors such as defence, machinery, industrial automation, transportation and high-tech equipment. We are experienced in working with demanding tolerances, controlled documentation, revision management, traceability and customer-specific quality requirements. Our strength lies in combining multiple production technologies, reliable project coordination and long-term supply capability from a single manufacturing partner.
