As a top manufacturer of connecting rods, we aim to exceed our customers' required levels in processing accuracy, which contributes to enhancing the added value of our products, such as low vibration and low noise. Currently, in response to market demands for environmental considerations through aluminum connecting rods, we are advancing the adoption of aluminum alloys with excellent mechanical properties (strength, wear resistance, etc.) and the development of new processing methods. In recent years, leveraging the know-how we have cultivated in the cutting processing of aluminum connecting rods, we have consistently proposed high-quality, high-precision raw materials, as well as cutting processing and surface treatment for other metal components.
