Why are common parts known as standard components useful in assembly lines?

Common parts, often referred to as standard components, are essential in assembly lines primarily because they are easy to obtain and inexpensive. Utilizing standard components streamlines the manufacturing process, as they are widely produced and available from numerous suppliers. This availability reduces lead times and increases efficiency, allowing manufacturers to avoid delays caused by sourcing custom parts.

Moreover, standard components typically have established designs and specifications, ensuring compatibility with various systems and reducing the need for extensive modifications during assembly. This not only helps in minimizing costs but also enables easier replacement and repairs in the production process, contributing to overall operational efficiency.

In contrast, complex processing and costly production associated with custom-designed parts can slow down the assembly process and increase production costs. Therefore, the use of standard components is a strategic choice in manufacturing that enhances productivity and reduces expenses.
