Custom 5-Axis Machined Aluminum Automotive Valve Body with 100 Percent Leak Tested CNC Machining

Valve bodies are machined on 5-axis centers so spool bores, cross-drilled galleries and port faces are produced against a single datum, then honed to Ra0.4 µm. Every body passes a 1.5 MPa leak test before packing, and the serialised test log travels with the shipment so your incoming inspection can trace each unit back to its machining batch.

• Single-Datum 5-Axis Work — Spool bore and port positions machined in one setup for correct flow alignment.
• Honed Spool Bore — Ra0.4 µm bore finish reduces spool sticking and internal leakage.
• 100% Leak Tested — Every body pressure tested at 1.5 MPa with a serialised test log.
• Clean Internal Galleries — High-pressure deburring and washing remove chips from cross drillings.
• Custom Port Configuration — Thread types, O-ring grooves and mounting faces built to your hydraulic schematic.

Send a 3D model or 2D drawing and our engineering team returns a machining quotation within 24 hours, together with material and finish recommendations. OEM and ODM are both supported: geometry, tolerance band, thread class, surface treatment and laser marking are all adjusted to your specification, then locked in with a first-article sample before mass production.

Parts are bagged in PE film with shock-proof foam inserts inside export-grade corrugated cartons, keeping machined surfaces free of nicks in transit. Barcode labels, desiccant bags and palletized packing are available on request.
