Injection/Overmolding

Injection or overmolding techniques in composites involve the process of injecting or molding a composite material over a pre-existing structure or component, enhancing its functionalities or adding protective layers. This method allows for the combination of different materials, such as polymers or composite resins, to create a cohesive and integrated final product. It's commonly used to reinforce or encapsulate parts, providing improved strength, durability, and resistance to environmental factors.
