Lightweight Power: A Leap in Performance
We are Taizhou Liuhuan Machinery Co., Ltd., based in Yuhuan, a key auto parts hub in China. We have a strong hot forging line and extensive capabilities in aluminum alloy forged rocker arm machining. Our aluminum alloy forged rocker arms are high-performance chassis components for cars and machinery. We use aerospace-grade aluminum such as 6061 and 7075 for precision die forging, achieving optimal metal grain flow for a strong, durable product.
The Weight Advantage: Lighter and Stronger
In comparison tests, our aluminum rocker arm is up to 60% lighter than a traditional steel version, while its dynamic strength and fatigue life are significantly higher. This advantage comes from our careful material selection and advanced forging process. The reduced weight lowers the moving mass in the engine, helping it reach higher speeds more quickly-a critical factor for high-RPM, high-power engines.
Material and Process: Precision You Can Rely On
We use pre-stretched aluminum that meets AMS or GB standards. Precision forging with a high-tonnage press ensures dense, defect-free material. All subsequent CNC machining steps are performed with strict control, keeping mounting hole positions within 0.1 mm. We are IATF16949 certified, so every step is under stringent quality control.
Custom Design: We Work with You
We do more than produce parts from your drawings. Our engineering team can help optimize your design using finite element analysis to improve the rocker arm's shape. We can further reduce weight while maintaining stiffness, support various shapes, hole positions, and hollow designs, and add sintered bushings, so the part is ready for installation.
