basic information
【Content】 ■Point 1: Characteristics of Base Materials The important point in aluminumizing connecting rods is the base material. It is necessary to select the base material considering the required strength, production lot size, cost, and the characteristics of each base material. ■Point 2: Shape and Names of Each Part The characteristics of aluminum connecting rods include the ability to directly slide with the piston pin and crankshaft. Compared to iron-based materials, not only does it reduce weight, but it also allows for cost reduction by decreasing the number of parts such as half-shell metals and bushes. ■Point 3: Positioning of Cap and Rod There are various methods for positioning (combining) the Cap and Rod. The main methods include in-lay, reamer, serration bolts, dowel pins (knock pins), spring pins (dowel bushes), and flat methods. ■Point 4: Accessory Parts ■Point 5: Tolerances of Representative Parts □For other functions and details, please refer to the catalog.

Company information
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.
