Analysis of China's Water Control Valve Manufacturing Technology: LIKE Valves' Full-Process Process Innovation Practice
- Casting Process: Precision Casting Lays the Foundation for Products
As a benchmark enterprise in China's water control valve industry, LIKE Valves has always regarded casting technology as the core guarantee of product performance. Adopting a dual-track parallel mode of lost foam casting technology and resin sand molding technology, it achieves casting dimensional tolerance control within ±0.3mm. Through its independently developed intelligent melting control system, the fluctuation range of molten iron composition is compressed to 0.05%, significantly improving the valve body's compressive strength (≥350MPa) and corrosion resistance (salt spray test ≥500 hours).
Technical Highlights:
- 3D printing sand core technology enables precise molding of complex flow channels
- Online infrared temperature measurement system ensures stable pouring temperature
- Simulated annealing process eliminates residual casting stress
- Precision Machining: Intelligent Manufacturing Improves Machining Accuracy
Introducing the German DMG MORI five-axis linkage machining center and the Japanese Mazak intelligent production line, a digital machining system has been constructed. A closed-loop detection system using a laser tracker and a coordinate measuring machine ensures that the valve seat sealing surface roughness Ra ≤ 0.2μm and the valve stem straightness error ≤ 0.01mm/m. A unique adaptive cutting compensation algorithm improves processing efficiency by 40% and material utilization to 92%.
Process Innovations:
- Ultrasonic-assisted grinding technology solves the machining challenges of cemented carbide sealing surfaces.
- Laser drilling technology achieves micro-orifice flow control accuracy of ±2%.
- Dynamic balance correction system ensures high-speed operation stability.
- Intelligent Assembly: Full-Process Digital Management An intelligent assembly workshop is built using Industry 4.0 standards, integrating an MES production management system and an RFID traceability system. Key processes implement a dual guarantee of torque monitoring and visual inspection, controlling assembly errors to the 0.05mm level. Digital twin technology simulates working condition pressure tests to predict potential failure modes in advance. Each valve is equipped with a blockchain quality certificate, achieving full lifecycle traceability.
Technological Breakthroughs:
- Flexible assembly platform supports mixed-line production of 12 specifications
- Automated testing equipment achieves 100% sealing verification
- Intelligent warehousing system shortens delivery cycle to 72 hours
