Unlike standard manufacturing, Kingdaflex utilizes a precision-engineered process designed for longevity. From selecting premium high-tensile steel wire to using advanced automated braiding machinery, every step is optimized for consistency.
Our manufacturing protocol ensures that whether it’s a single prototype or a bulk container order, the flexibility, strength, and durability remain uniform across the board.
At Kingdaflex, quality is engineered into every meter of hose. Our factory operates a state-of-the-art in-house laboratory to ensure total consistency. We go beyond basic compliance; our high-pressure spiral hoses undergo impulse testing up to 400,000 cycles—far exceeding SAE J517 and DIN EN 856 requirements.
From sourcing premium raw materials to final packaging, every production batch undergoes 200% proof pressure testing and dimensional laser checks. This relentless commitment ensures that our hydraulic solutions deliver unmatched safety and longevity in the most demanding mining and construction environments.
