Custom Manufacturing Capabilities
We manufacture CNC machined hydraulic components from your drawings, samples, or design concepts. Our engineering team works closely with you to optimize designs for manufacturability, reduce production costs, and ensure reliable performance in demanding hydraulic applications.
Drawing-Based Manufacturing
Produce hydraulic components directly from your 2D drawings, 3D CAD files, or physical samples. We support all major file formats including STEP, IGES, DWG, DXF, and SolidWorks. Our engineers review every drawing for manufacturability and provide feedback on design optimization, material selection, and cost reduction opportunities before production begins.
CNC Machined Hydraulic Manifold
Precision CNC machined hydraulic manifold blocks with complex internal cross-drilled passages, cartridge valve cavities, and mounting surfaces. Our multi-axis CNC machining centers produce manifolds with precise hole positioning, smooth surface finishes, and strict dimensional tolerances. We manufacture manifolds for mobile hydraulics, industrial machinery, and fluid power systems.
CNC Machined Hydraulic Valve Block
Custom CNC machined hydraulic valve block components including directional control valve bodies, pressure relief valve housings, flow control valve bodies, and proportional valve components. We machine valve blocks from carbon steel, stainless steel, ductile iron, and aluminum with precision bore finishing, lapping, and honing for optimal spool fit and sealing.
Hydraulic Spool Manufacturing
Precision hydraulic spool machining with tight diametrical tolerances, fine surface finishes, and precise land geometry. Our turning and grinding processes produce spools with excellent wear resistance and accurate metering edges. We manufacture spools for directional control valves, proportional valves, servo valves, and pressure control valves in various sizes and configurations.
