Modern solenoid valve production lines integrate precision manufacturing, automation and intelligent control, aiming at high efficiency, precision and quality. Advanced lines usually include automated assembly, precision machining and online inspection modules.

1. Highly Automated Assembly Core

As the core of the production line, the fully automated assembly line transfers valve bodies, spools and other components between stations via jig chains or tracks. Key stations use servo presses and high-precision displacement sensors (GT) to achieve 0.01mm-level press-fitting accuracy. Leading lines can reach 4 seconds per valve with an annual output of millions of units.

2. Key Processes & Intelligent Inspection

Key processes ensure product consistency and reliability: servo presses monitor force and displacement during dynamic core riveting, while laser welding controls parameters precisely. Full-process inspection, including 100% airtightness testing (low and high pressure), guarantees qualified key indicators like leakage rate.

3. Precision Machining & Flexible Customization

High-end lines adopt CNC honing, achieving valve hole accuracy ≤0.001mm and cylindricity ≤0.002mm. Rapid changeover technology supports multi-model production; customized products go through 3D design, strict material selection (e.g., 316L stainless steel), dust-free assembly and 72-hour aging testing.

4. Intelligent & Green Manufacturing Trends

MES systems realize real-time production monitoring and full quality traceability to reduce defect rates. Water-based cleaning agents replace oil-based solvents to cut VOC emissions.
