Insert molding is a manufacturing process that can be considered a form of modularization. In insert molding, plastic or other materials are injected or molded around pre-inserted components or inserts, creating a single integrated part. This process allows for the combination of different materials and components into a single unit or a modular providing enhanced functionality and ease of assembly.

By using insert molding, manufacturers can achieve several benefits, including:

1. Enhanced product functionality: Insert molding allows for the integration of different materials and components into a single part, providing added functionality and features. For example, electrical connectors can be integrated into plastic parts, reducing assembly steps and improving overall product performance.
2. Improved assembly efficiency: Since multiple components are integrated into a single part through insert molding, the overall assembly process becomes more streamlined. This reduces the number of separate parts that need to be handled and assembled, resulting in improved efficiency and cost savings.
3. Increased design flexibility: Insert molding enables designers to create complex shapes and structures by combining different materials and components. This flexibility opens up possibilities for innovative product designs and improved aesthetics.
4. Enhanced product durability: The bonding between the insert and the molded material in insert molding results in a strong and reliable connection. This improves the overall durability and longevity of the product.
