Modular assembly is a manufacturing process where products are built using standardized units or modules. These modules can be easily combined or rearranged to create different configurations, allowing for flexibility in design and production. This approach simplifies the assembly process and can reduce production time and costs. In industries like automotive and electronics, modular assembly enables manufacturers to quickly adapt to changing market demands. By using interchangeable parts, companies can efficiently produce a variety of products without needing to redesign the entire system. This method also facilitates easier repairs and upgrades, enhancing overall product longevity.
