Heavy Automotive Valve Couplers

High-Vibration Stress Targets

Heavy duty trucks demand robust hydraulic components. An automotive client required custom spline shaft adapters and heavy flanges capable of withstanding extreme mechanical torque without metal fatigue.

Forging and CNC Turning Operations

We utilized heavy-forged 40Cr alloy steel profiles directly sourced from Tianjin industrial zones. The blanks were turned on high-rigidity CNC lathe machining stations to generate dense, tight threads. To protect against the corrosive effects of highway road salts, we provided a custom high-thickness zinc electroplating finishing layer.

B2B Commercial Success

The parts successfully withstood extensive destructive torsion stress testing. Our localized raw material advantage in Daqiuzhuang CNC factory enabled us to offer direct factory-level pricing with a 25% logistic cost reduction for the buyer.
