Production Process
Raw Material Selection: High-grade alloy steel (such as 40Cr/4140) is selected to ensure high strength and good elasticity.
Forging and Forming: Integral forging and precision lathe machining are employed to ensure lever straightness and dimensional accuracy, minimizing deviations.
Heat Treatment: Quenching and tempering processes improve the tensile strength and toughness of the steel, ensuring no deformation during long-term use.
Knurling: High-precision knurling is performed using CNC knurling equipment to ensure uniform texture and consistent feel.
Surface Treatment: Chrome plating/oxidation/spraying treatments are applied as needed to enhance corrosion resistance and appearance.
Assembly and Debugging: Bearings or copper bushing systems are installed, and rotation tests are conducted to ensure smooth operation without jamming.
Quality Inspection: Straightness tests, rotation tests, and load tests (up to 1000lbs+) are performed to ensure compliance with export standards.
