Sub-assembly

A sub-assembly refers to a component of a larger assembly that is itself made up of several smaller parts. Typically, a sub-assembly is manufactured separately before being installed or combined with other components in the final assembly of a product. Sub-assemblies are common in engineering and manufacturing processes to enhance efficiency and streamline production.

Sub-assembly meaning with examples

• In the automobile industry, each engine part is considered a sub-assembly, such as the fuel injection system, which is assembled separately before being integrated into the vehicle's main assembly.
• The electronics manufacturing sector often uses sub-assemblies, where circuit boards are produced as separate units before being mounted within larger devices such as smartphones or laptops.
• In furniture manufacturing, a sub-assembly can refer to a pre-assembled cabinet section, which allows for quicker assembly of the final product on-site, reducing labor time and costs.
• During the construction of airplanes, various sections, like the tail and wing assemblies, are built as sub-assemblies, which are then transported to the assembly line for the final installation and integration.
• Toy manufacturers often create sub-assemblies for different parts of a toy, such as the wheels or figures, allowing for efficient packaging and shipping as all components are ready for final assembly.
