Tight-tolerance port networks and sealing faces held to ±0.0005″ for leak-free pressure control.
High-pressure manifold blocks machined for consistent port alignment, leak-tight sealing, and repeatable production releases. We quote quickly, hold bores and faces within ±0.0005″, and eliminate cracked blocks, mis-drilled passages, and last-minute line-down emergencies.
Precision CNC Machining for High-Pressure Manifolds
We machine high-pressure manifolds that manage dense port layouts, intersecting passages, and demanding sealing requirements in hydraulic power, motion control, and test systems. Blocks are typically billet steel, aluminum, stainless, or ductile iron with tightly controlled port locations, bore finishes, and mounting geometry to keep pressure ratings and leak performance predictable in production.

How We Deliver Consistent, High-Accuracy Results
Critical port-to-port and bore relationships held together, preventing misalignment that causes leaks and valve timing issues.
Process plans minimize setups, reducing stack-up error across intersecting passages, sealing faces, and threaded connection patterns.
Documented programs and inspection plans repeat results across batches so production releases match the PPAP or first-article build.
Standardized setups and scheduling give predictable lead times, reducing expedite requests and emergency air-freight for rushed builds.
