Custom Hydraulic Manifold Valve Block – Precision CNC Machined

Core Strengths

1. Tight Position Tolerance

   All circuit & thread holes held within ±0.02mm to avoid stacking leakage and valve spool jamming.

2. High-Grade Sealing Surfaces

   Ground mating faces: Ra ≤0.4μm, flatness ≤0.02mm/100mm for reliable high-pressure sealing.

3. Anti-Deformation Processing

   HT300 cast iron / 6061 aluminum blanks with 24h stress relief after rough machining to stop dimensional shift.

4. Complete Internal Deburring

   Abrasive flow polishing clears cross-channel micro burrs to prevent seal damage and system failure.

Standard Production Process

• Unified machining datum + 22±2℃ constant temperature workshop to cut thermal errors

• Multi-pass light grinding to avoid thermal deformation

• Full cleaning flow: brushing → abrasive polishing → ultrasonic wash → air blow; 100% endoscopic channel inspection

• Surface options: blackening for cast iron, food-grade hard anodizing for aluminum (no flaking paint)

• Mandatory 25MPa 5-minute pressure leak test before shipment
