Core Foundation of Technical Adaptability: Dual-Driven by Patent Matrix and Manufacturing Capabilities
Ningbo Flag-up’s technical adaptability stems from the dual advantages of “core patents as the foundation + precision manufacturing as the underpinning,” forming a deep alignment with the needs of main engine manufacturers.
(I) Patent Technology Matrix: Targeting Key Pain Points in Excavator Hydraulic Control
Since its establishment in 2010, the company has continuously built targeted technical barriers. Its core patents cover three key areas: operational precision, system safety, and structural optimization.
Operational Precision Enhancement Technology: The buffered foot valve patent developed in 2015 adopts a dual-damping valve design, fundamentally eliminating operational jitter in small excavators and improving work precision by over 30%. This precisely matches Shanxi TZ’s performance positioning of “high-precision operations” for intelligent excavators.
This technological breakthrough resolves control deviations caused by lagging mechanical feedback in traditional hydraulic valves, becoming the core technical touchpoint for collaboration with TZ.
(II) Precision Manufacturing Capabilities: Hardware Support for Meeting Verification Indicators
High precision and stability in manufacturing are crucial guarantees for the practical application of patent technologies.
Processing Precision Control: Advanced equipment such as multi-axis honing machines is adopted to achieve strict control of key dimensional tolerances within ±0.02mm. This precision level is 40% higher than the industry’s conventional standards, laying the foundation for the consistency of hydraulic components.
Taking deep-hole processing as an example, optimization through damping shock-absorbing tool holder technology solves the vibration problem in traditional processing, resulting in a hole wall roughness of Ra≤0.8μm and ensuring smooth spool sliding.
Relying on precision processing capabilities, the after-sales PPM (parts per million) rate is below 500, fully meeting the performance requirements of TZ’s 6T and 8T models.
(III) Achievements
After two years of single-piece sample installation and small-batch supporting, the company now fully provides supporting components for 6T and 8T models. Leveraging TZ’s bulk orders, Flag-up has realized production capacity ramp-up (with 3 sets of pilot valves required per 6T excavator, the annual supporting volume can reach 10,000 sets). It has also enhanced its brand premium by virtue of TZ’s industry status.
