A round dowel pin, also known as a parallel pin (straight pin or cylindrical pin)

It is designed for use in molds or assemblies consisting of two or more parts. Its primary function is to ensure precise alignment when the mold closes, allowing for the production of high-quality products. These pins help accurately position adjacent sections of the mold, ensuring proper alignment between the upper and lower halves.

Applications：

Positioning in Fitting Components : Used to align two mating parts accurately. Examples include piston pins in automobiles and motorcycles, as well as positioning pins in molds.

※Dowel pins can be precision-engineered to meet specific requirements, offering flexibility in both diameter and length to suit diverse applications.
